 Re: Techart PRO FAQ | |
Some lenses like the 35 Cron v2 and 4 that have bad reps on Sony are OK if you stop them down to mid apertures. The Kolari mod just gives you 1 or 2 wider apertures that you can use. And because WATE and MATE are retrofocus lenses, Kolari mod makes only a small difference that you can see at 100%. They work perfectly well without it.
Re: Monochrom fantasies: I also found that the original A7R and the original Monochrom didn't differ noticeably in image quality when printing up to 17x22. So I'm assuming the A7RII and newer Monochrom are also about the same – except with Sony you can use the LR/PS sliders to change the underlying tones in BW files, which IMO is a substantial advantage. For this reason I've never wanted to go back to Monochrom.
But we're wandering away from the TAP, except to say there are lots of options with it.

You're using a Kolari-modified A7R II, right? That's why the M-Hexanon 28/2.8 performs well. I got my hopes up for a moment because I mistakenly assumed that you were talking about a stock A7R II. The M-Hexanon 28/2.8 and 35/2 performed so poorly on the A7R that I've never bothered to try them on an A7R II. Neither the Kolari nor the front-end filter modifications are practical for me so occasionally I think (gasp!) about a used M Monochrom. Then I reconnect with reality.

I have no wobble yet, but this thread has convinced me to use a regular adapter and manual focus most of the time, and the TAP only when I really need AF. That way I can get my money's worth of use out of it and put off the arrival of wobble.
As above, I too found the 35 2.8 and 55 FE to be rather unpleasant lenses. All they can do well is resolve detail. Last week I tested a number of 50mm lenses to see which would be best in the corners for stitching, and the 55 FE wasn't even the sharpest, and seemed too contrasty. It didn't really block up the highlights, it just didn't seem to offer as much differentiation of highlight tones.
The outcome of testing was that with the Kolari mod, I can use Leica lenses at middle apertures for stitching without any noticeable difficulty in the corners. So I'll be using MATE and WATE for landscapes, and other Leica lenses in TAP when I need AF.
Besides Leica, a C/Y Planar f1.4 and a C/Y f3.4 35-70 also gave more pleasing results than the FE 55, from the standpoint of being sharp enough and also rendering nice tonal gradations.
I rather liked the 28 f2 for street shooting, but sold it when I got TAP. 28 Summicron doesn't play well with Sony, but 28 Hexanon-M is good with TAP. Because 35mm is better for me, I use 35 Cron v4 in TAP, plus RX1rII, not Q. When I use RX with a Metro grip and Thumbs Up and a wrist strap, it feels like an autofocus M4.
