What is the native ISO for the a7rII?
Like I know certain isos perform better and have less noise because of how they work (from what I've read)

I heard 100 and 640 are the two to mess with

Any thoughts? Obviously lower has less noise but ya

Yep 100 and 640.

Guess I'll stick with those.

Do native lenses have better luck with focusing in lower light?
I know sometimes if I'm like 100 shutter 1.4 and 640 ISO the sigma art 50 hunts a bit. Seems odd to me but is the mirrorless system really this bad in "lowlight"?

Yes, native lenses are far better in low light than adapted lenses. Thats one of the main reason why I ended up fully switching to native for my AF lenses

With regards to ISO unless im shooting landscapes I have my camera set to Av mode and auto ISO and dont even worry about it. I have NR switched off in lightroom 99% of the time. The ISO performance is just that good. 100 and 640 are supposed to be the best ISO values so theoretically for everything below ISO 640 you can shoot at 100 and raise the exposure in post and end up with a cleaner image than if you had shot at the correct ISO. Same applies to values over 640 if you shoot at 640 and underexpose then raise the exposure in post it should be cleaner and have better dynamic range than shooting at the correct ISO.

I generally dont do this though and just shoot at whatever the required ISO is. There was a thread on FM forum about the technicalities of this a while back.

So mirrorless PDAF can only see half the light hitting the sensor. The hybrid AF systems that mirrorless systems employ are able to bridge the sensitivity gap by utilizing contrast detect AF. The MC-11 adapter enables hybrid AF with adapted lenses (most adapted lenses are PDAF only and don’t work too well in low light)….the downside the the mc-11 is that the AF motors in DSLR lenses are not made for contrast detect, they are designed for phase detect. Contrast detect involves really high speed hunting at the end of the AF cycle. The AF motors of native lenses are driven by electromagnets that can change direction so quickly that the hunting is basically imperceptible. DSLR lenses in contrast are designed to move to a specific distance in one motion and are not optimized for the hunting that is a normal part of contrast detect AF. It works, but not with nearly the finesse of a truly native lens.

Another review Sony FE 85mm 1.8 vs GMaster 85mm 1.4




I literally just clicked on this to see the Jedi Snow White. :-D Not gonna let go of my 85L, but Jedi Snow white was awesome.

Another shot from Barker Dam in Joshua Tree. I wasn't even going to process the image due to some bizarre magenta banding in the clouds, but then I realized a square crop would get rid of them. ;)

check out this Manny Ortiz test with the 100mm F2.8 STF

it's weird because.. i know the t-stop value is 5.6, it's showing as F5.6 in camera as the fastest you can go or open although the rendering looks like an F2 to me.

Background blur of an f2 lens...DOF (subject focus) of an f2.8+ lens. Really interesting lens

Hi Sony users, I'm a Canon guy exploring possible options of a move to Sony, I skimmed through some of the 2120 pages of this thread and I see a lot of great photos posted and talk mostly about the Sony A7RII, but not a lot about the A7SII, is the A7RII the overwhelming choice of most Sony users? I don't quite know if I can tell what the difference is in them? Who does the A7RII fit more and who does the A7SII work better for? I'm looking for a smaller camera than my 5D Mark II, that would give me good photos and good video too. I want to start documenting things like my sons baseball games and team, with photos and video, making some creative video with small short clips strung together, then add some nice photos too. I'm guessing one of these two cameras might work for my needs?

I know Sony won't beat Canon when it comes to "sports" photography, but not sure I want it for that part, sure take some shots here and there, but mainly portrait type photos, vacation type, street walking, etc...and then video.
I really am just wanting to find out more about the Sony brand from you users who use it everyday. I don't have a lot invested in my Canon gear, I have the 5DMKII, 24-70MKI and 70-200MKI oh and a 50 1.4. I could really go anyway with my change, Nikon, Sony, whatever or stay Canon and go 5DMKIV. I don't know how deep into video I'd go, maybe I'd take it more beyond what I do with stills, not sure.

So really just wondering if you all can help me figure out of those two Sony's or is there another, that would be a good fit and what the major differences are?

Yeah, the a7R II is the better/best all-around FF mirrorless camera. If you're really into video - if that was your main reason for buying the camera (which you've said it isn't) - then the a7S II can be better suited for capturing fullframe 4K video. Video is the whole reason the a7S II exists. But even videographer Dave Dougdale explains that though he's more of a video guy, and owns both a7R II and a7S II, he still prefers using the a7R II 95% of the time. Watch him explain here; it might help you:

this is another video that shows, very clearly, that it seems to be a magical lens when you shoot near MTF (a head or head and shoulder shot) - i.e. it gives the image a 200F2 look, but as you step back, for a full body portrait, it renders like you are shooting F5.6

this lens definitely has a place in the bag of portrait photogs when used for head and shoulder shots

for wedding photogs, who primarily shoot the 70-200, this is probably a better choice than a fast 85 for these types of specialty portrait shots


Hockey and wedding photographer. Favourite camera / lens combos: a 1DX II with a Tamron 45 1.8 VC, an A7Rii with a Canon 24-70F2.8L II, and a 5DSR with a Tamron 85 1.8 VC. Every lens I own I strongly recommend [Canon (35Lii, 100L Macro, 24-70F2.8ii, 70-200F2.8ii, 100-400Lii), Tamron (45 1.8, 85 1.8), Sigma 24-105]. If there are better lenses out there let me know because I haven't found them.

A 7S is more geared towards video. But the a7rII can also shoot 4K in about 25 FPS I believe?
As you can read from my most recent post I also just switched from Canon myself and regret nothing besides not doing it sooner. Kanon is phenomenal, they always have been and they always will be but the technology you get with Sony on top of the portability is unbeatable. Especially if you want to take it traveling you can get a small a 6300 with the kit was basically fit it in a little fanny pack.
There are plenty of videos out there that can compare the cameras and let you know all the super awesome features of sony but until you put your hands on one and compare the photos of something like the a7r Mark III you won't really know how truly great they are. I tell everybody it's the first time I feel like I got my $3100 worth. And I have honed the Canon 5D Mark III and I've shot with a few of their high-end series as well for weddings and stuff

The a7R II can do 4K in both fullframe and super35 (aps-c) mode at either 24fps or 30fps. Plenty capable. However, the a7S II does fullframe 4K without any pixel binning, so theoretically sharper than a7R II in FF.

I was shooting some kid portraits this morning before school (heavy backlit), about an hour after sunrise, using the FE 85 and hood, couldn't replicate the flare issues. Whatever issue on flare is not very apparent when using the hood
