After seeing some really nice atmospheric shots with the Voigtlander 17.5mm f0.95, I decided that I'd look around for a used copy (they're around 700 new) to see what I made of it. So, I found one on eBay at a reasonable price and received it today. I won't repeat what lots of reviews on the internet have said already, but thought a few test shots wouldn't go amiss. All from raw on the E-M1. Aside from some CA and defringing, the shots are using LR defaults (so no additional sharpening). The crops are 100%.

1) Portrait - 1/30s f0.95, ISO 200

The DOF is very thin, but the bits that are in focus are reasonably sharp:

The vignetting that's apparent is not as bad as it seems since the lighting was a ceiling spot that naturally falls off at the edges of the image.

Remember, this is f0.95 and the lighting was very poor. Stopping down to just f1.2 brings the sharpness up quite a lot and in better light the contrast is better which apparently improves sharpness too.

2) "Landscape" (not much of a landscape) - 1/60s f0.95, ISO 200

Centre crop:

Edge crop:

The poor sharpness at the edge is field curvature since if I focus on an edge feature, it's almost as sharp as the centre.

Here's the same crop at f4:

As you'll see, there's still softness there.

So - not a landscape lens, but absolutely great for people shots. The DOF separation at f0.95 is quite spectacular:

The light was very poor - 1/8th sec (thanks IBIS!!) at ISO 200.

A crop of the above (remember this is at f0.95), but with a teeny bit of extra sharpening added (40 on the LR slider):

The young girls pupil is matching your lens. :cool:

Certainly be interesting to see what you can get out of it, when you have got used to how best to work with it.

They all look fairly soft to me, very reminiscent of 35mm film lenses, which, after all, is what Voightlander is famous for. I like the images, but I am looking forward as you will get more used to the lens.

How can you conclude it is not a landscape lens on the basis of testing it at f0.95?

One of the shots is at f4 Harold. I haven't tried it at f8 yet though, so maybe I should reserved judgement - it's just that staring at f0.95, f4 is already lots of clicks away from wide open!

Hard to conclude from a handful of shots taken in quite challenging circumstances. I'm sure it will find it's use, especially wide as the designer's envisaged.

f0.95 is just shy of f2 in terms of DoF when normalised for 35mm photography. Just imagine how challenging a FF 50/f1.4 or a 50/f0.95 would be!

Interesting as a test but it would be unusual to user wider than f8, more likely f11 for landscape. So I suggest that you have not tested the lens for "landscape use" but have seen what it will do on distant trees, etc. at some of the wider apertures. There is a difference in context.

Yes, I know - I had the Canon 50/1.4 back in the day. Nice lens, but focus accuracy wasn't its strongest point.

With my summilux 50 I can't blame the camera or the lens, only the operator!

I would have expected more blurring of the background at f0.95? Especially in your daughter's portrait, the window seems to be at least a few feet away.
