So the on-sensor PDAF systems have trouble finding the subject when the lens is extremely defocused...I forgot the reason why..something to do with the spacing of the phase detect sensors with an on sensor system. With native lenses it appears that the a7rII in hybrid AF is able to use contrast detect to mitigate this and its a non-issue, but since hybrid AF is disabled with adapted lenses, the PDAF system has nothing to fall back on when its struggles to find the subject at telephoto focal lengths. If the image is not extremely defocused the adapted 70-200II actually focuses pretty quickly, so the work-around I found was to manually pre-focus the lens when the lens needs to move from one extreme focus distance to another....this has worked pretty well, but its been so much of a bother to me that when I was pack my bag for a shoot I often hesitate to pack the 70-200 2.8II because of the risk of missing a key moment.

To answer about how the GM's AF performance.....neithe​r the 70-200GM or the 70-300 have issues focusing at their longest focal lengths. The 70-200GM in particularly focuses very quickly....as in DSLR lens fast. I'd say its the fastest FE lens I've used. I actually went home on my lunch break and tested this out on my daughter. Ugly light so don't judge the IQ, but you can tell she was twirling around by her posture, and eye focus had no issue getting the shot.

I'll have lots of chances to put the GM through its paces this weekend and will keep you guys posted

Cute little girl. Looks like the 70-200GM is a winner

just wanted to inform that the Sigma MC-11 has a software update

i installed it

it seems to work better with the Tamron 45 & 85 (these really didn't work before) - still not perfect with the 85 - but it works

i experimented with the Canon 70-200 II IS at 200mm, both with the 1.4xIII on and off, and seemed to work very well in AFC mode

quick question,does that mc11 work as native on sigma lenses but only as a reg adapter on your canon lenses,do u get eye focus and af tracking on say canon or your tamron lenses. i have 2 af adapters already and both are ok but not great. neither does af tracking or any other native feature.

This explains a lot...and has been my workaround but now it makes sense. Thanks.

Off topic:

My internet is really slow but i have a fast comcast internet connection.

My suspect is my Apple airport extreme wifi router. It's more than 5 years old. Now it won't stay green, blinking orange only and really hot. Do you think it's time to replace it? I'm thinking it might not up to todays tech already.

It's still giving me net but really slow.

Any recommendation? Thank you.

Comcast now by default provides Integrated Modem+Router (single device) and signal strength is pretty good.
I can stream movies from almost 50ft distance between TV and router. You may ask comcast to give you a newer modem.
I think that costs $10 a month.

I actually bought my own modem to remove 10bucks from my bill and i'm sure it's new and compatible. That's why my suspect is the apple airport router because it's more than 5yo already.

have you try resetting your network? modem... router...

if it's the same, yeah maybe.. 5 years old is getting old for tech these days :P

id also check the modem. Not sure if yours is rented or you got your own. The ones given by the provider usually stinks. old routers may not have the high speed support that your isp/package is capable of. After few years I found out that I wasn't using the full speed of what I had because the router they provided was only at 25mps max wireless. After switching to a better router that was purchased, I got the 50 mbps that I should according to the plan I pay for. I now change isp and have 100 mbps.


I like to use http://www.speedtest.n​et/ (external link) to test the speed, both wired and wireless.

I replaced my old Apple Airport with an Asus dual band wireless gigabit router about a year ago. It really sped things up.

I have routers at my mom's house that are much older, wireless G.... Stupid reliable, I have them located in the attic, so resetting would be a pain. Havent needed to reset them once, which is pretty darn crazy.

I'm extracting about 60 images from a backdrop. I'll be a master of refine edge after this. I have to install the PS CC14 for the refine edge. the new select and mask sucks big time. 40 images done now, 20 more. I'm paid $7.50 per image and I can finish about 10pics/hour.

Superman having some Jello. Eye AF is definitely awesome to have. This was shot with the FE 55.

I'm not a portrait shooter so my WB may be off. All natural light; well natural as in no strobes or speedlights. The lights in the kitchen were on.
