70-200GMII is way better than 35GM when using extension tubes: no field curvature, very good image quality, low focus breathing (35GM's focusing breathing is kinda insane like a zoom lens) and the AF is still very snappy.
Interesting data from lensrental... Sony users rented a shxt load of batteries per body compared to Canikon, even though Sony is the indisputable king of battery life. I guess video guys are all using Sony.
They always say Canon system design this good that good far better than Sony but there are shits so retarded that I just couldn't wrap my head around it. When Sony's buffer is full the burst rate slows down. When Canon's buffer is full the camera just stops until it's cleared.
Been watching reviews of the new 100-400GM and holy shxt this thing is a beast. Performs exceptionally well with 2x TC, very good stabilization and bokeh, practically no weakness.
Also tested the Sigma 70-200. Even though the burst rate is only 15FPS you still got 30FPS for view finding which is crucial.
If you can get 10FPS hit rate with 3rd party lenses then I guess at the end it's not that bad
Had some fun with A7V today
Unlike my A7C, A7V's recall function can also change the shutter type (mech/e) and some other stuff. The new speed boost function is also great.
So I guess A7R6's 12bit boost mode is not a big issue since you can switch the mode easily...
Good chance that A7R6 has more ADCs for each column compared to those partially stacked sensors. The ADC is working at slower speed hence lower noise, but this approach needs much more chip area and is significantly more expensive.
I have only one concern left... A7V's long exposure just sucks and I guess it's the same for all partially stacked sensors. Hopefully A7R6 doesn't have the same issue...
good news is even in E-shutter (not 12bit though) A7R6 still looks very decent just as I suspected. They probably use fully stacked sensor instead partially stacked to make sure it's both fast and clean
