No surprises ... still a great lens in the APS-C scope as well.

Added some macro sample images here (which are not really suitable for a bokeh analysis due to the extreme focus spread).

Nice, thanks for the extra samples, Klaus. While your bokeh test shot showed the OS version to be less "creamy" than the great former version, it seems that anyway the bokeh is still quite pleasant. Very nice to know!

Yea but that is on a 8 mp camera <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='Smile' /> surely the special quality fade with higher density.

There's already an APS-C review of it here ...

This (and other threads at the site) have a lot of pictures and comparison to other 'alternative' 100 macros (mostly leica and zeiss)

Good technical question!

However the stunning images that I have seen are made either with

1. Sigma 150 + 1.4 TC

2. Sigma 150

3. canon 180

4. Sigma 180

5. Sigma 180 + 1.4TC



This is the list in canon land.





Honestly I have not seen stunning images from voigtlander 125. I wonder why it is not popular by top photographers. Please let me know, if you have some links with good macro shoots with voigtlander 125. I’m sure that they exist.

Send me an F-mount adapter and I'll take care of it. Just don't tell Klaus that I'm planning to review another exotic lens <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Wink' />

You can check out my review on the D700 here :

;-)



regarding the bokeh fringing greatness in the review of the Sigma, I would guess the Voigtlander 180mm f4 SL1 would preform well too in this dept, but with smoother bokeh than the Sigma.

Nice little "review", One niggle:

"It is also probably slightly more effective a lens to use for portraits, due to it’s combination of shorter focal length, and larger aperture resulting in less blurred shots."



It is not due to the combination of shorter focal length AND larger aperture... the larger aperture counters the shorter focal length instead. So... only the shorter focal length can be attributed for what you have found, not in combination with the larger aperture.



However, your (nice) article lacks images showing this difference, are you really sure it is there?

125 / f2.5 = 50mm aperture

100 / f2 = 50mm aperture

This suggests that the blurring of the background, for both lenses being used wide open, and with similar framing, would have an equal amount of blurring, as both apertures have the same size. So... any differences could then only be in the quality of the blur, the smoothness of it (bokeh) or the slightly wider field of view from the Zeiss making the background possibly a tiny bit more "busy".

I think you've got the wrong end of the stick here...

Typically a longer focal length requires a faster shutter speed for less blurred shots. When I say blurred I'm not talking about background blur, I'm talking about reducing the effect of camera shake.

I'm this regard the Zeiss seems to win on both fronts having both a larger aperture, and a shorter focal length. Obviously the difference is small in both aspects, but it is there.



Regarding background blur, the optical design (shape of glass elements etc) of these two lenses is undoubtedly more important than their focal length/max aperture ratio, but with my calculations I did back in the day, the 125mm focal length trumps the f2.0 aperture... They are so close in the aspect though I considered it not worth mentioning.



Cross sections of the lens designs would perhaps of been a more interesting feature to add to the review.

Well, I still have mine but I'm going to sell it. Regarding the scarce availability it is not really worth to do another review of it.

May I ask why you're selling this rarity?
