Really liking the pics with 135/1.4 ! May pick one up to use with my Z8 with megadap. Anyone know if there will be a z version ?


You're adapting E if you want it on Z

Fine, I'll adapt the Sony version I use some e mount gems that way (ZA 50/1.4 and Loxias - love those) Ideally if they ever produce an ef version I will take that as I can use it on z and also gfx (should be nuts on a gfx). I dont think its going to happen though..

Yes, that would be good, but this is something easy to avoid to as a photographer. If I am shooting handheld, which is fine with the shutter speeds that cause problems then I shoot in full manual shutter or electronic shutter on a stacked sensor camera. There is really no reason to be using EFCS when you are handholding the camera and especially anywhere near the shutter speeds that cause problems.

EFCS is for shooting on a tripod at slower shutter speeds. We all mess up settings from time to time, but this isn't a hard one to avoid at

Okay....maybe I'm not a photographer then. Or maybe I should not be shooting fast lenses, or maybe I shouldn't be shooting fast lenses with certain Sony cameras. Or maybe there should be a warning label on non-stacked Sony cameras.

So under the assumption that I can "loosely" be called a photographer, and I have a Sony a7R V, and I have fast lenses. How is it easy for me? I was shooting sunflowers using electronic shutter on Sunday, because I was switching between wide open and stopped down shots with the 50-150. An amazing hummingbird moth comes by briefly. I can quickly change back to mechanical, and if I had this extra "feature" available I'd be done. But my default for mechanical is EFCS on. So now I have to fiddle with that. I do have a custom setting for birding, I should have switched to that. I have that set to full mechanical.

So I ended up with some jello shots before I could get my settings more appropriate. I should have just switched to EFCS and lived with consequences I guess. I did end up with a keeper or two.

It's hard for me to buy an A1/A1 II just because occasionally I shoot with a fast lens at wide apertures. Not every situation is perfectly planned. When it is, it can be avoided more easily.

I would argue it would be easier, for me personally, if Sony would just provide this setting. The a9 series isn't really up my alley, and basically that leaves the A1s.

Sorry, not feeling well today. I should lock away my laptop on days like this. Please just ignore me (hopefully not permanently.)

My frustration isn't really with your post, more with me reliving the occasional situations where this drives me crazy. For your camera it makes sense.

When I had A7III, I tried to be very diligent about it and I still ended up with some failed shots.
Though, maybe my mistake was that I never ruled out EFCS completely...

I don't visibly see what folks talk about with EFCS bokeh. Can someone school me? Is this a thing I need to pay attention to? I've almost exclusively used EFCS on my Canons, and now on my Sony as well unless I'm using flash.

Well, you can't unsee it once you see it.
So, careful what you wish for .

You need to shoot at large aperture with very high shutter speed, to see it best (e.g. 1.2/1.4 at 1/4000+s).

No worries, Tim. I always appreciate both your work and your thoughtful comments. For me I only use EFCS on a tripod and I have a custom setting for tripod use. So, for me this doesn't come up. Not saying that is right, but that is my experience. I don't see shutter shock when I hand hold, so I just use manual shutter on my A7r V all the time for that. I hate switching shutter modes and when I used to do that I would often forget which mode I was in. So, I simplified things. Hand holding, manual shutter; tripod, EFCS and I almost never use full electronic. Doing it this way may not be optimal, but it is easy and for me it works. I hope you feel better soon.

Even if Sony gave you the choice of Electronic Shutter, EFCS, Mechanical.....I could quickly switch between the 3. But the options are Electronic and Mechanical.....and there is another setting for the type of mechanical.

Maybe I would be better served to have the default but full mechanical and then selectively switch into EFCS.

Just frustrating as this is not like putting a man on the moon in terms of complexity to implement. My GFX100S II has it, although it's less of an issue there for me.

Anyway, sorry to clutter up this thread.

That’s an old video and Manny STILL hasn’t changed the title of the video even after about 100 people asked him to in the comments. He totally confuses people because he is saying “electronic shutter” when he should be saying “efcs”. They are totally different things!

It’s very easy. When shooting at 1/1,000 and faster with a large aperture, just switch to silent mode and that’s it. Perfect backgrounds for portraits.

Indeed my very first video 8 years ago was about this and then 5 years ago I made one to clarify that Manny video as it is indeed wrong and confusing to viewers

The reason why EFCS has effect on bokeh is because two shutter curtains that are used are at different distances from the sensor.

I have investigated it and described it here in visual way: https://jtra.cz/stuff/essays/bokeh/index.html#efcs

So full electronic shutter does have this problem and full mechanic does not have it either. Why EFCS is used at all? It is cheaper and smaller as there is only one curtain (so a7C line has only this one). It may be also faster. In mirrorless cameras full mechanical shutter means that live view feed before taking shot needs both curtains open, then when taking picture the first mechanical curtain needs to close and that could take longer time than just resetting the sensor. AF for moving subjects needs to be more predictive because of that longer time between last AF sensors seeing light and picture taking.

EFCS also has problems with HSS modes of flashes. I had some colored banding in past with a7iii and Godox ad200 outdoors in bright light, probably 1/4000s or faster. Full mechanical shutter fixes that. Or use ND filters to get to slower speeds or even to avoid HSS (with this ad200 it is also more power efficient by about 1.7EV IIRC in non-HSS mode even when accounting loss from ND).
