Interesting, why this is good option?

Because if you use digital zoom/crop you lose most of the AF modes, but with APS-C crop (and the panorama modes) you don't. Plus the Rii has enough pixels to give you good res in the smaller format, so you get two primes for the price of one, as Addy said.

It's also interesting that with A-mount lenses on the LA-EA4 you get lock on AF which works despite the poor number of PDAF sites, whereas on the LA-EA1 that is not allowed. Can't figure out why not.

Thank you!

That's a good idea and I've decided to do that. Though on the A7Rii you cannot set a custom button to do that and have to go into the camera menu each time.
Hmmm, to my surprise you are right. I can do it on my A99m2 and I thought I had it set as well on my A7r2... You can set so many things the way you like that it is always surprising that there is something you cannot set...

I don't see a reason to want an APS-C crop unless it is the full size of the sensor. It is more crop than is needed for most APS-C lenses. I miss a root 2 crop and would prefer a more granular crop control.

The A7R cameras do have their best video capture in Super 35 mode.

Well, I decided to go for a s/h Samyang 35mm f2.8 for <<£200 for the moment. Not macro, but I'll give it a go and see how I get on with it. It looks small enough to be a good choice on the Nex-6 too, if I want AF instead of the Meike 35mm f1.7 MF lens I currently use.
I can still keep a lookout for a Tamron or Sony later if I feel the need.

Good choice, I once bought this lens together with another Samyang 24 f2,8 for about 350.

Quite light, quite sharp, fit to purpose.

Well, if you have a 35mm lens on your camera and there is a 50mm scene, the 1.5 crop is nice. I do not understand why that is difficult to understand. For some people photography is an experience, not a scientific exercise.

Anyway, the Samyang 35/2.8 is a good choice! Cheap but good. Enjoy it.

Hi
I hope you like your Samyang, I bought a s/h one from Nandbytes here on Dyxum and it's been fine on my A7m2 except for occasional focussing hesitation - there is a software update available which sounds as though it will cure it but the adaptor to do so costs £50 - I just missed a sale price a lot lower after Xmas and am too mean to pay that much !
Also sits well on the a6000, but gives approx 50mm FL which is not a favorite of mine.
Good luck

The Sony lenses get updated via the came4ra, but the Samyang need an adapter? What about Sigma and Tamron?

Sigma and Tamron have licenses so they update through the camera. Viltrox and Yongnuo have USB ports on their lenses. The Zeiss Touits require shipping to Zeiss, but I believe the Batis line get updates through the camera. It sounds like Tokina requires shipping their lenses to them.

I have an extra Samyang dock.

How do you find the lens firmware version?

Just go to the "version" in the menu (7Rii: toolbox, page 6 bottom of the list), it will give the firmware version data for the camera as well as the lens attached.

Btw, my Samyang 35/2.8 says version 3, need to check if that's the latest

EDIT: latest version is 6, but you need a dock to update it , so I guess it needs to wait.

I haven't noticed any performance differences with any of the updates.

Thanks Matthew, even more reason to avoid spending 65 , don't think it's worth it for me, I only have one Samyang lens.

Just bought the 35f2.8 to add to the 18f2.8, but it sounds like their's no urgency in getting a dock.

The one thing I do notice with both lenses is that the AF flutters quickly (cycles several times) every time I request focus (eg by half-pressing the shutter), even if there is no actual change in focus, suggesting they are using only CDAF and not PDAF.

Not at all impressed by this on a camera with hybrid AF - A-mount lenses on the LA-EA4 are much better this way, just moving a tiny amount once.
