Really looking forward to the Voigtlander 20/3.5 coming back now, just phoned the repairers and they say it was out by quite a bit!

It should be back with me early next week, I hope it looks a LOT better. If it does, I will be keeping it.

I'll post some results as soon as I have it back and the weather is reasonable.

There is one in local store in EOS mount. Will go and test tomorrow...although I am planning for a 28mm lens, I can't help but be attracted to the Voigt...

Comparisons of re-colimated Voigtlander 20/3.5 with Canon 20/2.8 USM

Test scene as before, (sadly the horse box had been taken out). Colour change from earlier results is called Autumn. However these are taken in VERY dull flat conditions.

Focus on green pot at 5', F16 to see depth of field. Pity I can't put them next to each other. The Voigtlander is more colourful.

Near centre of image, 100%, very little has changed, both reasonably sharp.

In the distance, again very similar results to before, The Canon having greater resolution and the Voigtlander smudging the leaves of the distant tree. (Possibly slightly less difference than before?)

However at close distance I can see a marked improvement in the Voigtlander from my earlier results. (Thank goodness, I was beginning to think the £50 re-collimation fee was wasted!)
Exposure exactly the same in centre, so the Voigtlander has darker corners than the Canon.

I don't think the difference is enough to keep the Voigtlander, but at least I can now sell it knowing it is working as it should be.
