Voigtlander 15MM

Go to last post
Hi Mark,

Not sure if you mean the 15 or the 21. They have a 21 listed, almost same price as I paid. I think so far that this is the best bang for buck lens I've ever purchased!

Go on... you know it makes sense..

Hi Jono. Tim and others
This lens looks really good, especially for the money I noticed
that ffordes have one S/H
copy and paste this link and follow S/H store link
https://secure.ffordes.com/shop/Store/index.htm
at that price.... even I'm tempted!

That's not what his conclusion was though- on the link you posted:

"So while the Voigtlander wins the resolution race, it really does suffer from pronounced vignetting at this aperture. In sky, I like vignetting. Vignetting helps. Vignetting is good. Vignetting works. But I don't want to see it in brickwork, thanks.
Vignetting one stop down is forgiveable, but at f8 it's out of order".

Not exactly a ringing endorsement, vignetting at F8!!! even a 1930's WA Hektor doesn't have that sort of performance, and the CV 15 is certainly better on the M8, though to be fair the lens was never designed to fit on a SLR, so the terrible results are to be expected.

It sounds to me like you have your logic the wrong way around. The 15mm SL Heliar was designed to fit an SLR (this version comes in Nikon F mount), but the 5D was never designed to handle non-retrofocus wide angles. This does not only affect it's mechanical design (it has a mirror), but also it's sensor design.

The M8 was (by using offset microlenses), which causes it to perform better with the 15mm.

So don't blame the Heliar! I wouldn't be surprised if the 1930's Hektor would also vignette if you could mount it on the 5D, for the exact same reason.

No you misunderstand my point, I don't suggest that at all!!!!!

Exactly my point, the post was suggesting that the Heliar on a Canon was somehow a usable option I quote him here:

I was simply pointing out the article did not suggest that mounting a Heliar on the FF Canon gave satisfactory results, in fact vignetting was poor even at F8.

I in no way meant to suggest that the Heliar was a bad lens, in fact on a FF film camera it is a great performer especially at its price point.

But it's hardly surprising that it is a poor performer on the Canon as the 5D/Heliar combination is not one that was originally perceived for either product, whereas the offset micro-lenses on the M8 will give far superior results with this lens than the 5D
Understand now?

Did you read the review to the last page? Why did you pluck sentences out of page 2 and 3 of the review instead of looking for the 'end verdict' where the end verdict should be--on the last page?

You can't miss the vignetting at all apertures, which according to some reports is also a feature of its performance on the rangefinder cameras for which it was designed.

It should be noted that correcting for this vignetting is a piece of (non-deleterious) cake. A five second Quick Mask/Gradient/Curves action on each image would harmlessly fix the problem and give a better result than the Sigma every time. The Voigtlander at least gets enough information to the sensor to allow corrections to be made, like this:

(cut to uncorrected/corrected A-B comparison, where the corrected corner isn't all that brighter than the uncorrected corner anyway)

So, end verdict , he did find vignetting at all apertures (like you so like to emphasize), but he did NOT find it to be a problem--not only did he find it 'usable with some vignetting correction', he found the image quality better than the Sigma 'every time'!

I'm obviously reading a different conclusion to you:

http://www.16-9.net/lens_tests/15mm_test1f.html

What he says that although the lens is sharper than the Sigma (but remember it's a zoom) it has to have vignetting correction on all shots at all apertures, has to have the mirror locked up etc etc

So it's possible to mount a range-finder lens on a FF SLR and get all round worse performance than that lens mounted on a RF camera (surprise surprise)

So it works with all the caveats and if thats acceptable to you then fine, but for me it's far from an optimal situation.

...except for having a true 15mm FOV vs a 20mm effective FOV as on the M8, and making a 77% larger picture out of the same lens. No wonder it shows more vignetting!

I just posted this as interesting extra information about this lens, nothing more. I have no vested interest in either Leica or Canon.
 
It is a great lens... This was shot handheld at 1 second wide open..... This Heliar is just one of those lens deals you can't go wrong with.



Best of the season to all.....

Yes but it does not when mounted on a film FF RF, so we can conclude that there is a problem with the way light falls on the sensor, or the micro lenses, tele-centric ratio etc etc

Sure thanks; but I don't think that the 5D with a WA or pancake lens is really a viable alternative to a RF interesting though in a freak-show type of way.

Do I see purple fringing? Other than that, it is rather impressive.

A few days ago I barely resisted buying 1.2/35 Nokton and went with an old 2/35 Summicron instead. Just treied it on M8 and boy... I am not trading this bokeh for 1.5 stops of lens speed!

I hate to be the negative one, but the shot doesn't thrill me - I'm rather put off by the excessive fringing. I think the Luminous Landscape test on the RD-1 showed the 12mm to be far superior for digital.

I'll be attending a Leica rep event tomorrow, and I plan to test out my CV Nokton 40/1.4 Single Coated lens on the M8 (I am assuming they'll have the camera there). It is a pretty stellar lens, and with the 1.2x FOV multiplier should produce a nice 48mm FOV on the M8.

With film at least, I have never seen a hint of distortion, softness or CA anywhere in the frame. Even wide open.
