    Posted: 09 February 2021 at 20:22
I recently acquired an A77 and out of curiosity I checked the shutter count. From one image to the next the shutter count increased by two. I find this some what odd.
I searched through all of the camera settings and couldn't find one that might cause this.
Then I did an initialization. The same thing happed after initialization. Any thoughts?

Set electronic first shutter to on. Otherwise the shutter moves twice per shot - once before exposure starts and second time after exposure ends.

Thank you. That did it. Hard to tell how many exposures this camera has made. Guess it doesn't really matter.

But you know how many times the shutter moved. It seems the A77 shutter is designed for about 150.000 exposures/movements. Tells you nothing about anything else that happened to the camera. Enjoy it - it seems a lot of people recently got a "new to them" A77

I will share some pics as soon as I learn this camera. The controls are some what different from my other cameras.

The first few shots I took with the 77 were disappointing. I was using a Sony 10-250mm. Then I switched to a Tammy 18-270mm (I'm a slow learner). Finally I popped on a Sony 16-50mm f2.8 SSM. A world of difference.

Should have been Sony 18-250mm. Sorry about that.

That would be something, a 10-250mm

Ha yes, me too. I've just been reading up on electronic first curtains to try and understand under what conditions I should switch it off.

For me it's always off unless I'm shooting from a tripod or macro shots which is usually with flash and it should always be off when doing flash work.

With the A77 I almost always kept the EFCS on, only a few limited situations when it could have an effect on images.
1: Any HSS flash shooting can, likely will, cause banding.
2: High shutter speeds. Least mine started underexposing at high shutter speeds. In extreme situation could also introduce banding even under natural light.
3: Fast lenses shot wide open. EFCS can affect how bokeh in foreground or background is rendered.

Why does a tripod make a difference for you?

or macro shots which is usually with flash

So you're saying you do use it with flash?

and it should always be off when doing flash work.

Or you're saying you don't use it with flash?

There should be no problem using EFCS with normal flash at normal sync speeds.

EFCS sould be turned off when using the Minolta MFC-1000 or the similar Sony MT24AM flash controller.
For non-macro flash work it is often not necessary to turn off EFCS.
