| p.1 #2 · Calibrating Leitax chips? |
I've found that Leitax consistently provides the most precise adapters for Alt lenses on my EOS bodies. Well, Leitax isn't an adapter, but that's moot. Anyway, I don't use focus confirm (FC) chips on my Leitax or any other mount adapters, and so I can't comment on the settings, but I can say that I expect the Leitax 'fit' should be about right. I guess this implies that the required Auto Focus Microadjustment (AFMA) setting should be close to zero. OTOH, I've never dealt with a FC chip that has AFMA 'smarts'. I guess the Dandelion has grown up. Damn weeds!
The Oly 50/1.2 is my second-most favourite 50/1.2 (after the EF 50/1.2L). I used it to great effect on my 1DsIII with the stock focus screen for shooting helicopters hovering over a ship flight deck, at night - that's pretty dark.
Have you asked Leitax about this?
P.S. IMO, AFMA is for AF lenses. I'm quite content to use manual focus with my manual focus lenses (plus a bit of LiveView helper, when appropriate).
