Still trying to figure out this camera, but when shooting video, I assumed/hoped that the camera would automatically focus and/or track people's eyes; but I find I have to touch the person on the LCD first and then it works brilliantly—and I see the square over the eye until I hit the center button. Otherwise, I don't see the square over the eye, so not sure what it's focusing on. Is it focusing but not showing the square or do I have some setting wrong?

      A7RV memory card confusion

      By FunWithCameras · Posted

      You will see approximately NO difference when shooting stills - if you shoot lossy compressed RAW at full speed you might start to build a buffer backlog, and that will clear a little faster with CFeA cards like the Lexar Gold or Sony Tough. But it is marginal. You WILL see a difference if your shoot 1000+ images and download them with a fast reader to a local SSD - they will download much faster than even the fastest SDs. But that’s a marginal reason to get them (unless you are in the habit of shooting thousands of images - I do that more on the A1 for obvious reasons) The CFeA cards are pretty tough - I have some Sony and some Lexar, all 160GB - but I mainly got them for the A1 - I use them in the A7RV because I already have them. I don’t think you really need CFeA cards (buy them if you want, though). I’d be tempted to get a couple of 128GB or 256GB Sony Tough G SD cards instead. The G cards are worth it because they enable things like high frame rate 4k, and they download faster. Basically, I’d recommend fast UHS-2 SD cards (300 read / 299 write is good) over slower UHS-1 cards. Whatever you do, don’t buy 90MB/s cards! I like the Tough cards, but like you said the Lexar Gold are much cheaper in CFeA - I bought a couple to try them, and to encourage Sony to drop their price!

      A7RV memory card confusion

      I have been shooting Sony for 5 years (A7r3,  A73, A6400).  Taking delivery of the A7r5 in a few weeks.  I will NEVER (never say never!), shoot 8k and am primarily a still pro shooter.   I plan to get 2, Lexar Professional 160GB CFexpress Type A Gold Series cards Up to 900MB/s.  The Sony tough cards with the same spec are close to $200 more for a pair.  IS THIS speed spec overkill considering I'm shooting primarily still, and occasional 4K videos?  Thanks in-advance for any replies.

      Firmware upgrade for non Sony lenses

      By JCCabin · Posted

      The Sigma 105mm macro lens DG DN Art is on Ver.02 2023.01.26. Though I haven't upgraded that lens, I have upgraded a couple of other recent Sigma lenses and it is quite simple using the Sony camera and detailed on the Sigma website. Do a quick Google search and you will find the information you seek. Link: https://www.sigma-global.com/en/lenses/a020_105_28/?tab=support&local=firmware
