Another of those "Isn't m4/3 really good" posts.

A couple of bits of news today made me put my Voigtlander 28mm f/2 Ultron lens onto my Panasonic GX1 and shoot a few test pictures. 

Firstly Dpreview announced that some Australian photograohers have posted some Fuji X-Pro 1 shots. Unfortunately this seems to have crashed their (the aussies) website. This is one of the reasons I use a Google blog and flickr for the majority of my picture hosting, since they have the servers to cope with heavy amounts of traffic.

Secondly, Andrea at 4/3rumors has got a very strong indication that the sensor for the new Olympus OM-D or E-M5 as its apparently going to be called, is the same as the GX1. There seems to be an air of disappointment over that, but thats not a feeling I share, as I think the GX1 sensor is very good indeed, particularly at low ISO's. In terms of sharpness, the ability to show what lenses are capable of and overall "pop", its a sensor that works really well. The test shots I took with the Voigtlander lens are sharper than using the same lens on either of my Sony's (NEX-5n and NEX-7) and are pretty close to what I got from the lens on my Leica M9. 

In fact the files were surprisingly good. This is the first time I've tried the lens on this camera and I was expecting it to produce good results, but in fact the images have exceeded my expectations. Here's a few 100% blowups.









So all nice and sharp, good resolution, virtually no CA. 

I don't know whether its because of all my film scanning or just general overkill with the constant discussion of small differences between cameras, but I'm becoming less and less concerned with the "next big thing" and starting to think that I may go back a bit and work with the cameras I liked working with, irrespective of whether they are "state of the art" or not. I'm actually considering an Olympus Pen again (There's a surprise! Not!) and maybe even a GF1. I've said on numerous occasions, if I used the cameras I really want to rather than what I think I should for my work, it would be m4/3 all the way. 

Tests like the one above make the decision (if I ever get round to making it) a little easier.

A Sony fanboys rubbishing of the Fuji X-Pro 1. (That should get a few hits!)

At their press conference the other day, Fuji went through the somewhat undignified process of putting up a chart and placing all other cameras in inferior positions. The Fuji X-Pro 1, was of course at the pinnacle of style and quality. The only problem with doing this is that you have to be pretty sure that you can deliver the goods. From what I was reading as this "rubbishing" chart was unveiled, it seems as if m4/3 and NEX were relegated to a pretty lowly position.

My reaction yesterday was to actively want to use both m4/3 and NEX cameras. It is somewhat disappointing when companies feel the need to emphasise the negatives of their rivals rather than their own positives. Fuji aren't alone in doing this, but it was a cheap shot, and of course complete BS. 

So yesterday afternoon I went out with what I consider to be the best all-round CSC you can buy, the Sony NEX-5n, just to see what it can do. Unlike the Fuji, not a lookaleica, however to get into the spirit I decided to use two metal Voigtlander lenses, the 28mm f/2 Ultron, and 75mm f/2.5 Heliar. The camera and lenses looked rather nice with leather case, strap and add-on viewfinder. No-one would mistake it for a Leica, but hey you can't have everything.

I was particularly interested in seeing how the NEX-5n performed as a general all-round camera, and I did what I virtually never do, which was fire off a series of continuous shots. Its a fairly modest 2.3 fps, but I held down my finger on the shutter button and it starting firing and then it just kept going and going and going..... eventually I stopped as it was getting tedious. I got up to 25 shots in total of which I've put together 16 below. It would have done more, and while these were jpgs only, there was no buffer lockup whatsoever.

I wonder how the "Pro" Fuji will do at something like that?

In the place I was in I've always wanted to take a particular shot. There is a main railway line behind a canal basin and I've always wanted a picture of an express train with canal boats in the foreground. I've had several go's at it and haven't actually managed to get what I wanted usually due to AF hunting and shutter lag. Using manual focusing to pre-focus I waited for a train and one duly thundered along at about 60mph.

As you can see I managed to get both ends of the train frozen and pin sharp in exactly the right position. Since the shutter button on the NEX-5n is instantaneous, it was a question of my reactions, fortunately even with freezing cold fingers I got what I wanted. If you think I was there for hours trying to get this I wasn't, this was my first and only attempt.

I wonder how the "Pro" Fuji will do at something like that?

Fuji have made a lot of fuss about their new sensor array. Lots of diagrams of coloured squares. More is better, right? This apparently gives full-frame quality in terms of high ISO performance, image quality and dynamic range. Though why they want to duplicate the DR of something like a Leica M9, which is pretty poor, I'm not sure. However since they had felt the need to relegate the Sony NEX system to the status of an also-ran in their "chart of merit" here's a few examples of what the NEX-5n can do.

Fuji's previous lookaleica, the X100 (The Professionals choice), wasn't known as being particularly particularly good at either auto or manual focus. Since I was using manual focus lenses, I had no opportunity to use AF, but I would mention that I could probably have shot off half of the images in the top montage before the X100 had even locked on to something. In terms of manual focusing, the NEX systems focus peaking feature takes this to new levels.

I decided to give it a reasonable test by attempting to focus on some swans using an aperture of f/2. OK, this isn't a cheetah racing across the Serengeti national park, but those swans can swim pretty quick... really.

_DSC1437

_DSC1445

I will admit they aren't that quick on land, but the object of the exercise was to see how quickly I could follow something around, continually altering manual focus at a very wide aperture. As it happens I could do that very successfully. Not all my pictures were perfectly composed but of the 20 or so shots I took, every single one was perfectly focused.

I wonder how the "Pro" Fuji will do at something like that?

On the subject of wide apertures Fuji make a great thing of how their camera / lens combinations can do all this fancy depth of field stuff (as if other cameras can't) Heres a couple of examples of the NEX-5n / Voigtlander combination in action.

Finally an example of how the NEX-5n copes with dramatic, contrasty lighting and the colour depth its capable of producing.

The shot above is a multi-image panoramic stitch, which is a 100MB file that looks simply breathtaking on my screen.

So, all of this probably reads like some Sony fanboy having a pop at Fuji. Well, yes it is and it isn't. Its my reaction to the nonsense that gets talked by camera manufacturers, internet pundits and your everyday internet forum contributor. As with the X100 there is the usual nonsense about how the Fuji X-Pro 1 (Couldn't they come up with a name without the Pro AND the now obligatory X) is going to change photography as we know it. I've seen "reviews" that are proclaiming that the new Fuji has better image quality than the Leica M9 and the Sony NEX-7 amongst others. This incidentally on the basis of a few, somewhat underwhelming, jpg samples on the Fuji website.

I'm still smitten by the look of the FPX1 (my new name for it) and though I'm telling myself that I'm going to wait and see what its capable of, the chances are that I will probably slap a pre-order in as soon as I can and wait impatiently for it to arrive. Even though I've been describing it as a lookaleica, I LIKE lookaleicas, and anyone who reads here on a regular basis will know that I go weak at the knees whenever I see anything with a hint of retro.

I do however feel my blood pressure rising when I read the nonsense that passes for serious comment on this thing. The almost religious faith that people put in the camera brand of their choice is amusing but at the same time unnerving in its ferocity.

I've been "bothered" recently by someone who seems to be trying to carve out a career as an internet stalker. An avowed NEX hater, he (I presume its a he) swoops on any of my posts when I dare to suggest that Sony make quite decent cameras and maybe we should actually wait to see if new wonder cameras such as the Fuji actually live up to what their manufacturers say about them. One particular set of snide comments to an innocuous post from me, pointing out that the FXP1 was actually quite heavy and how I personally was more concerned with weight rather than size, caused me to flip, with the result that I have now left a forum that I have enjoyed contributing to. However its either that or steam coming out of my ears on a permanent basis.

As I'm you sure you are all aware, I do make it very clear that what I write is personal opinion. I constantly write phrases such as "In my opinion" "It seems to me" "For me personally" etc. etc. I may, on the odd occasion leave one of these out, but if I do its because I'm not concentrating, and anyone who has read anything I write knows that I always endeavour to NOT present my personal point of view as a statement of fact.

However, I'll survive. I've been spending far too much time recently on forums anyway.

Returning from my rambles to the point of this piece, it may seem mundane and blindingly obvious to state that its perfectly possible to see the virtues of a particular piece of photographic equipment and also see its faults. It is also possible to see that one piece of equipment is good at one thing and not at another. It is also possible to point out that camera manufacturers may be prone to occasionally, possibly, be the teeniest bit biased when it comes to comparing their product to a rivals. They also, god forbid, may indulge in a bit of selective informing and exaggeration when it comes to describing the virtues of their new offering. And finally we can actually like something without signing away our souls to some multi-national and promising to proclaim them as the one true god of camera manufacture from now on and for ever more. OK, this is a bit over the top, but how often have you read and seen things that approach that level of nonsense?

In my opinion, to my mind, in my experience, from what I have seen and used, with regard to my personal use etc. etc. The Sony NEX-5n is a decent, capable, versatile high quality camera. It doesn't have as many coloured squares on its sensor as the Fuji, it doesn't look like a hand made German rangefinder, it doesn't (to my knowledge) have a soft core porn website but it works really well and does everything (and more) that I could ever want it to. I would also mention that you can buy a NEX-5n body and a couple of lenses for about half the price of the FXP1 body only, and if you want to investigate the wonderful world of m-mount lenses there are loads of S/H Voigtlanders, Zeiss's and even Leicas out there at prices within the range of virtually every serious photographer.

And last but not least, you can actually make an assessment of how it works for you since there are countless samples, reviews and user experiences to sift through. It may not be the second coming, but its here, you can buy it, and more importantly you can check out for yourself what its capable of.

Sony NEX-7 - Voigtlander lenses in use

Sony NEX-7 Voigtlander 35mm f/1.2 Nokton

Until yesterday, I'd only done some indoor tests with the Voigtlander 35mm f/1.2 Nokton and 75mm f/2.5 Heliar lenses on the NEX-7. Though these were very impressive, I needed to try them out in a real world situation.

Sony NEX-7 Voigtlander 75mm f/2.5 Heliar

I'm pleased to say that the promise of the testing was confirmed by this excursion. Very sharp results, with I'm pleased to say, very little CA and fringing once the lenses are stopped down from their widest apertures, plus excellent colour and contrast.

I seem to be whittling down the number of lenses I actually want to keep for the NEX-7, and its proving more difficult than I thought. The NEX-7 seems to throw more challenges at lenses than the NEX-5n. Not in terms of sharpness, as everything I've put on it so far has performed well or adequately in that regard (with one exception I'll come to later*) but in terms of CA, fringing and vignetting. 

These two Voigtlanders, however, are the equal of the Zeiss 24mm f/1.8 in terms of resolution, and apart from their fine performance, I really enjoyed using them. With the excellent focus peaking feature, they were a pleasure to use, and this Sony innovation really does open up the possibility of being able to use manual focus lenses with speed and accuracy. I'm sure something similar will start turning up soon in other CSC's, and I wouldn't be at all surprised if Leica are having a look at it, not neccesarily for their m-series cameras, but for this interchangeable mirrorless system they are apparently working on.

THE PROBLEM LENS
Sony NEX-5n Voigtlander 28mm f/2 Ultron
Sony NEX-5n Voigtlander 28mm f/2 Ultron

*The third of my Voigtlanders, the 28mm f/2 Ultron, however doesn't work very well at all. Apart from the vignetting and colour cast, its just not that sharp. In contrast to its performance on the NEX-5n, when it was very good indeed.

The problem seems to be that this Voigtlander is a symmetrical design (as opposed to retrofocus) There's a link here to a piece by Carl Zeiss on the difference. Not only is there a tendency to the vignetting and colour cast problem illustrated in an earlier post, but with certain types of sensors, there can be a reduction in sharpness also. 

Apparently this is the reason that Ricoh designed their m-mount module for the GXR system in the way that they did. According to my internet research on this, the NEX-7 sensor is configured in such a way as to make symmetrical lenses perform less well than on the NEX-5n, which is a different design. I'm not going to explain why this is, as I simply don't know enough about it to enlighten you, but I've most definitely seen it in operation, and what was a very good lens on the NEX-5n has suddenly become a quite poor one on the NEX-7. 

There are 28mm Leica lenses which apparently work fine on the NEX-7. Unfortunately they are substantially more expensive than my humble little Voigtlander, which seems to have accepted its fate and realised its destined for a new home anytime soon!!

So, the NEX-7 seems to be a demanding beast! In order to squeeze out the best value from those 24MP, it gets very picky about what works with it and what doesn't. I am prepared to continue trying to sort out my best options however, since when it gets it right the results are spectacular. Now can I really afford £4000 for that Leica 16-18-21mm Tri-Elmar, because apparently that works brilliantly with the NEX-7? No I can't. That was easy!!

Sony NEX-7 - Voigtlander 28mm f/2 Ultron

Following on from my piece on the m-mount problem, it seemed sensible to start my NEX-7 + lenses posts with the Voigtlander 28mm f/2 Ultron. The sun even came out for 10 minutes.

All of these images are uncorrected, and as you can see, in a real world situation its not that much of a problem. In fact there are many shots where it just won't be noticeable. Shots with lots of sky are more of a problem, as you can see above.

The 28mm performed very well. I was able to get very sharp results. I'm using the somewhat radical sharpening parameters that I developed for the Panasonic GX1, and they work rather well for NEX-7.


A few more observations on the camera. I said with regard to the NEX-5n, that the peaking function for focusing is the best method I've ever used for manually focused lenses. Since its in the NEX-7 also, it does make using MF lenses a breeze. Its better than the Leica rangefinder system, as far as I'm concerned, and of course allows a greater variety of lenses to be used. The Leica system is impossible for macro lenses, without adding on custom viewfinders and certainly lenses longer than 90mm are difficult, to put it mildly.

I can see an awful people who use m-mount lenses using the NEX-7 as either an additional or even replacement camera to a Leica M series, even allowing for the crop factor. Certainly its further confirmation that my decision to sell the M9 was a good one. I often miss it for what it is, but in actual use, the NEX-7 is going to be a far more useful camera, of that I'm sure.

I would also mention again the build quality of the NEX. Though small and light, it has a lovely metallic body. Somewhat in contrast to the somewhat plastic fragile feel of Panasonic m4/3 for example. However this isn't to say that its more sturdy, and certainly I've never had any problem with any m4/3 camera, it just seems that way. 

My trip out with it was very short-lived, as the dull weather descended again, but it was, as I imagined, a pleasure to use. Having the 5n's has certainly prepared me well, and I'm pretty comfortable with the Sony menu system now. I'm still not a great fan of it, but I've got all the buttons and dials set up as I want them and this will take care of the vast majority of setting alteration that I want to do.

Finally, in terms of the 28mm Voigtlander, I'm not sure about its future. The Zeiss 24mm is very close in terms of focal length and is a faster, auto focusing lens. The Voigtlander is a bit of a duplication and though it works very well on the 5n's. I'm not sure that its going to get used that much.

I've been so impressed with the Sony NEX-5n, that I've bought a second (silver) one as a backup. A couple of days ago I went out with it plus 16mm f/2.8 and 55-210mm lenses.

We don't have "Black Friday" in the UK, but certain retailers have a one or two day pre-christmas sale. One such was selling the NEX-5n + 18-55mm zoom for £20 less than the body only price, so with the intention of selling the zoom on ebay (I don't need two) I bought it. 

I also got myself the dedicated leather half case, which can be fitted without using a strap and it does wonders to improve the grip of the camera. I also tried the Voigtlander 28mm f/2 Ultron lens on the camera with the lens hood from my Olympus 12mm f/2 lens, which fits perfectly. It almost makes the NEX-5n look pretty. (Almost!)
