Infrared and alt lenses (on A7)


So sorry for the long delay. A7 only back from Kolari Vision 2 weeks ago, (with the \"thin\" 850nm AR filter)
and I\'m also struggling with a spate of migraines which photography doesn\'t help.

My very first look, and I really haven\'t \"peeped\" yet. (Contrast enhanced in Lr)
Lenses by row:
1. OM Z 21/3.5 sc F/3.5-16
2. OM Z 21/3.5 mc F/3.5-16
3. CV 20/3.5 F/3.5-22
4. Nik 20/3.5 F/3.5-22
5. P M 20/4 F/4-22
6. Tok 17/3.5 F/3.5-16

Oh dear, those don\'t look good for reflections/hot spots. Only the OM 21/3.5 sc looking useable,(first row), which is as it was before with the Protech 830nm 2mm(?) filter.
I don\'t really think the AR coating has done very much, though I need to get back to compare with the previous series to see just how great the difference really is...I\'d certainly hoped they\'d be a lot better.

I DO hope the corner sharpness is much improved or the amount I\'ve spent will have been a rather pointless waste of money...except of course for anyone following this thread and considering getting an A7 converted

What is now needed is the F/8 version of each, full size, to compare.

[EDIT] A quick preliminary look at the corners, shows they have actually been made worse by the Kolari mod, now even the OMs and the CV 20, that were sharp before, look poor! I can only conclude that something must have gone wrong with the conversion, as the corners should very definitely have improved. If it wasn\'t that I am in the UK, I\'d send it straight back to be re-checked, but as it is, postal fees and customs duties have exceeded the cost of the conversion! &
