NEX-5 and... Voigtlander 25/0.95

Hello from long time reader and first time poster The story goes as follows: I never liked big and clumsy DSLRs, so when m4/3 system was introduced by Olympus, I took E-P1 and E-PL1 subsequently, and built up a pretty fleet of manual lenses. Then, NEX system appeared on shelves, with its wild (after limitations of PENs) ISO range, so I switched to double set-up with NEX-5 for standard focus-length, and portrait shots, and E-PL1 for wide (with 9-18), macro and tele.

Now, when the Voigtlander 25/0.95 for m4/3 was announced, this was obviously an instant lure, the lens that could have compensated for PENs lack of high ISO performance. But then I had a further thought - what if this lenses low-light capability could be combined with that of NEX-5. To my surprise, Ebay offered this - http://cgi.ebay.com/M4-3-MICRO-FOUR-THIRD-MOUNT-SONY-NEX-E-MOUNT-ADAPTER-/320627191346?pt=Lens_Accessories&hash=item4aa6deae32#ht_1634wt_184 - I have no idea why someone would have needed this with focus-by-wire and digitally controlled aperture m4/3 lenses, but with Voigtlander 25/0.95 it came handy.

So, the Voigtlander arrived today, and I did a bit testing, which I think may be entertaining

The adapter is not a top-quality, so the lens actually rotates a couple of degrees when in the adapter. But, it does not move perpendicular to the matrix’s plane, so focusing is not actually affected. The thing just irritates.

The whole setup looks like this: http://www.flickr.com/photos/41626753@N06/5247889760/

As I expected (but deep inside hoped not to be the case), the lens is build precisely for the 4/3 sensor, so it vignettes heavily. But the clear part of the image impresses.

All shots are made on auto-ISO setting, in the night city, in aperture priority mode. All are unedited camera JPEGs

f0.95, focus to infinity - the adapter, actually, doesn’t allow that auto-ISO to 200, auto-shutter to 1/60

f1.4, focus to infinity - already cures the focus problem somewhat. I would imagine stopping down to 8 or so would allow infinity shots. auto-ISO to 200 still, auto-shutter to 1/50

f0.95, focus on the upper rim of the right light of the car, auto-ISO to 500, auto-shutter to 1/30

f8, auto-ISO 1600, auto-shutter 1/20. The “star” of the street lamp is nice.

My first feelings - I am very happy about the lens, its the sharpest large-aperture lens I own, and I clearly see a lot of situations where I could use the NEX-5+Voigtlander combo in spite of all the inconveniences.

PS: sorry, I don't seem to get it how to post images from Flickr, rather than just links. I would be happy to updated the post if someone could enlighten me

Seens to be a great glass.

Re: NEX-5 and... Voigtlander 25/0.95

Dude, that's awesome. I like the slight vignetting. Makes it look like a large-format camera shot since a lot of those lenses vignette or have light-fall-off on the sides. Come to think of it.. I think that's what you have.. light-fall-off.

As for Flickr, you go to Share, Grab HTML/BB code, and in that little pop-up you'll see a link for a JPG... thats the one you need.

Thanks for letting us know!
Waiting for more samples, also during day, maybe some portraits

Great idea!! the lens becomes a 37.5mm & DOF similar to F1.425 in FF which is ideal for street & night shooting.

Some daylight photos, as requested - although the weather today doesn’t provide much light.

The settings are the same, those are out of camera JPEGs (not that I agree with the way NEX-5 sets the exposure and renders colors - I usually correct those in pp).

0.95, auto-ISO 200, auto-shutter 1/2000. Set to infinity, but only the bench which is about 6m away is actually in focus.

Can’t promise the portraits, though - first, I just suck at them, second, I am not sure I have the guts to shoot portraits on the streets with such a short (focal length-wise) lens

Re: NEX-5 and... Voigtlander 25/0.95

Thanks!

What about minimum distance?
Is it approx. 17mm (if I remember correctly) from sensor?

17cm is more like it. Which is about 6cm from the front element

Thanks for the feedback. I also had the secret hope of the lens being usable on the NEX. The heavy vignetting bothers me in the day shots, not so much in the night shots, but the loss of infinity focus is a deal breaker for me. Do you think it is a problem of low-quality adapter or there is just no way the lens could get any closer to the sensor?

Re: NEX-5 and... Voigtlander 25/0.95

that is absolutely the adapter issue. I would have replaced it, but there seem to be no alternative offers. Still, closed down to 4 and beyond, this is not an issue.

Re: NEX-5 and... Voigtlander 25/0.95

thanks for doing this, i was really hoping this lens would cover the NEX sensor as well, and was considering doing this myself. it looks very good except for those pesky corners.

Those of us who use this excellent Voigtländer lens in front of its intended 4/3 sensor don't have to deal with those "pesky corners" because we don't have any sensor area outside the lens' intended imaging circle.

So it's really just a matter of cropping the NEX-5 image back down to something equivalent to the area of the 4/3 sensor. To me, stopping the Nokton down to f/4 and beyond isn't what the lens is about. After all, why would you pay € 900,- for an ultra bright lens only to shy away from using it wide open?

yeah, i was excited about it's possibility as a 35mmish f/1.4 equivalent dof & fov on the NEX. cropping it down to 45mmish makes it less appealing to me, so i'll withhold my buy reflex for now.

Re: NEX-5 and... Voigtlander 25/0.95 how useless

waste of money, terrible pics

Re: NEX-5 and... Voigtlander 25/0.95

true enough. While the combo does have its uses - like, shooting in low light some stand-alone objects with extreme bokeh, like this:

There is, unfortunately, no way to use Voigtlander as a standard lens on NEX. Not at least with the currently available adapter.

But no one will stop me from using this sweet glass on my E-PL1

Voigtlander 25/0.95 - crap quality at max aperture

It's crap, but did you expect anything else for that price?
