Hi guys,

I have found this weird difference between what I see in my A7SIII and what I've heard online and on YT, in that my second base ISO seems to be 10000 ISO and not 12800 for Slog 3. I found this out by increasing the ISO in low light to reach that magical 12800 where the noise clears up brilliantly, except mine is one ISO stop earlier from what everyone else seems to be getting.

Has anyone heard of this before? I am not sure if I should be concerned or not as everything else in the camera otherwise works perfectly however, this is bugging me a little. Another question is, does this mean that my first base ISO is also one ISO lower than the base 640 for Slog3?

I have noticed the same thing for pretty much every other gamma as well, also tried switching PAL to NTSC with the same result.

I'm currently running firmware 1.01.

I know this post is a bit old, but I wanted to say I experienced the same thing. I had my old Sigma 30mm f/1.4 aps-c lens on, without aps-c mode enabled on the camera, at f/1.4 the circuit triggers at 10000. Otherwise it is 12800. Seems like a bug with some lenses.

      2 Primes or 1 Zoom?

      By XKAES · Posted

      I'd opt for a small zoom, but I must admit that there seems to be a dearth of lenses in the e-mount in the 24-50mm range -- for some reason.  I have a small 24-70mm, but that's an a-mount Tamron.  Maybe you can find something by looking at lenses slightly longer.  I have a heavy, but small 24-100mm a-mount, and Tokina made a 24-200mm a-mount.  Maybe there are similar lenses in the e-mount.  Kill three birds with one stone.

      Well this! Thank you! I have been following suggestion after suggestion for the past 3 hours with my a7CR and never thought of removing the battery. Magic!

      2 Primes or 1 Zoom?

      By bs.shoots · Posted

      I recently got an a7cii and to pair with the compact body, I thought of getting 2 of the trio compact lenses, 24mm F2.8 and 40mm F4.0. (I already have a 70-200mm) However I stumbled upon the newly released 24-50mm F2.8 G. I'm not sure which to get - I like the small factor of the prime lenses ON the body because it's discreet and helps me blend in as an average tourist / doesn't make it obvious when doing street. But if I add the dimensions of the 2 primes together, it takes up more space in the bag than the zoom lens. BUT THEN, the weight of the 2 prime lenses is 110g lesser than the zoom lens. The zoom lens has the added benefit of being more versatile.   So now I'm stumped. Each has their pros and cons and I can't decide which to get. I'd like to hear the views of you guys who are more experts at this.   Edit: I'm a bit concerned about weight because the last time I went overseas my shoulders were aching from carrying too much. Which is why I was looking for small compact primes in the first place.
