Interim Update...
Went out today to try to see how well the combination would perform for tracking. Unfortunately, it is another abysmal day with terrible light and rain/mist with an Ev around 9. The usual cast of characters are hiding, so I did my best to try to obtain some additional information. Atmospherics were predominant and few subjects were airborne so I did my best to find something which was moving to better assess tracking. Overall, as I observed yesterday the AF was speedy with evidence of "green squares" dancing across the desired subject. AF-C wide seemed to be performing a bit better with a more accurate results. AF-C flexible small spot struggled a bit more today in circumstances of extreme contrast (dark subject, strong backlighting or reflections).
Overall, the af with this combination was impressive though again I don't have any data on how it will track BIF. PDAF appeared to be active as demonstrated in Wolfram's program. Once again, animal eye focus worked in some circumstances and the results were impressive. Look at the extreme closeup of the Bison with the reflection. The combination is pretty impressive considering the combination of a high MP camera, a TC, an adapter, and competitor's lens. Until the v1.29 update I was contemplating putting the 500 IS II up for sale to help fund a Sony 600 f/4 (that and a lot of panhandling and carwashes). For now, I'll be keeping it and using the lens for further exploration while using the Sony 200-600 for travel.
Some might ask, why the extreme ISO's and why not cut back the Tv? It's a fair point and since I was looking for BIF or moving subjects, and hand holding I wanted a high Tv to minimize the possibility of camera shake at 700mm. The a7riv requires higher Tv's for pixel sharpness compared for lower MP bodies. Interestingly, and importantly, I did dial back the ISO/Tv for the bison shots and the results are pretty impressive at Tv 1/400, demonstrating that the len's IS was working great (at least I heard it whirring). If I am not mistaken, IBIS does not activate for lenses it does not recognize so I suspect that only the IS was active.
BTW, the MC-11 has no weather sealing to speak of and I was out in a steady light mist without problems. Next time, I'll probably stop and put on the lens rain jacket. EXIF is listed as well as degrees of crop, and any other information. As usual, thoughts and comments are appreciated and hopefully the trolls will stay under the bridge.
