  1. According to Gary's book, the M screen is not as bright as the G screen. Do you have the special tool for removing and inserting the screens?
  2. So, to find out which focusing screen is installed without removing the screen, take a photo of an 18% gray card with a camera you trust. Then photograph the gray card with your a900 set to G screen and with it set to M screen. The photo whose exposure matches the photo taken with the camera you trust will be the one set to the screen you have installed.
  3. If you are interested, here is the link to Gary Friedman's web site: https://www.friedmanarchives.com/Alpha900/
  4. Gary Friedman devotes three whole pages to explaining the three different focusing screens (concentrating on the M screen), explaining the history behind the M screen, and explaining how best to use it. See pages 57-60 in Chapter 2 of Gary Friedman's excellent book, "The Complete Guide to Sony's Alpha 850 & 900". Mr. Friedman has excellent books on all of Sony's still cameras.
  5. FYI, the bulb being reflected in the second photo is a clear bare incandescent bulb.
  6. I just swapped out the G screen for the M screen in my a900. Unfortunately, there is no visible difference between the two in the viewfinder. There is a difference in exposure, however, if you don't have the correct screen selected. The exposure for my test scene with the G screen was 1/40 at f/5.6. If I changed the menu to indicate the M screen instead, the exposure changed to 1/60 at f/5.6. With the M screen installed and M selected in the menu, the exposure returned to 1/40 at f/5.6. For what it's worth, I have attached two images of the two screens below -- G screen on top and M screen on the bottom. The first image clearly shows the difference in the upper tab on the right. The second image shows the difference in the reflection of my work light. The reflection in the G screen is more focused and shows a definite interference pattern. The reflection in the M screen is more diffuse and the interference pattern is much less distinct.
  7. I don't know about the G screen (is that the screen that comes with the camera?), but I have an M screen (FDA-FM1AM), and it has no markings whatsoever. It is a fully unmarked "ground glass" type focusing screen. I assume you want to know how to set the focusing screen type in the tool menu, <tool3> -> <Focusing Screen> ? Otherwise, if you assume that option is set correctly, you can just look there!
  8. 240 MB is a huge file to edit. I do the vast majority of my edits on the raw files using Lightroom.
  9. With an "average" notebook you should have no problem editing the 42.2 Mb raw A7Rii files. I have a Dell laptop "XPS 15 9560 Memory: 32 GB Processor: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz[Cores 4] [Logical processors 8] Operating System: Microsoft Windows 10 Home." I easily process my A7Rii raw and occasional tiff files in Lightroom and in Photoshop. (I usually edit to JPEG rather than TIFF.)
  10. If something sticky was spilled on it, you might try applying a tiny amount of isopropyl alcohol with a Q-Tip.
  11. I don't have specifics, but in general, any model that was introduced after the summer of 2019 will not have the 30-min. time limit. For example, I have a Sony RX100 VII which I purchased in the early Fall of 2019, and it does not have the 30-min. time limit on videos. Some cameras, even though they have the 30-min time limit, will automatically start a new file for videos longer than 30 minutes, which can then be spliced together in a video editing app such as Shotcut.
  12. How small are your paintings? Unless you have some that are 4 X 6 inches or less, you probably don't need a macro lens. You do need a lens that has a short minimum focus distance, though. Instead of a macro lens, I think a copy stand is more useful for taking pictures of paintings.
  13. I save my M1 - M4 files to my laptop. After I save my images to my hard drive, I then re-format my memory card, and copy my saved memory data files back to the re-formatted memory card. I have an a7rii. My memory (M1-M4) data files are located in the SETTING>7RM2N subfolder. The memory file names are CAMPRO01.DAT, CAMPRO02.DAT, CAMPRO03.DAT, and CAMPRO04.DAT. To be clear, that's a letter "O", then a zero "0", before the memory number (letters "CAMPRO"+zero "0"+"1.DAT"). Of course re-formatting is quicker, but you can also select all images at once, then delete all in-camera, which does not delete your saved memory data.
  14. The best books out there for Sony cameras are by Gary Friedman. He covers every detail of every model and explains not only HOW to use each feature, but also WHY you might want to use the feature. Here is the link for the a7 and a7r book: http://www.friedmanarchives.com/sony-alpha-a7-and-a7r/ Then you will also need this this supplement for the a7ii: https://friedmanarchives.podia.com/supplement-sony-a7-ii
  15. If the focus noise is noticeable, it is not normal. I have a 70-200 f2.8 GM FE for my a7rii. In a quiet room, I can hear a very soft noise as it focuses. The noise does get just a little louder if it is in a focus mode that causes hunting. I don't have the f4, so I can't comment on the relative sound level compared to the f4. I do have an LAEA4 adapter that allows me to use with my old Tamron 70-200 f2.8 with my a7rii. (That lens is native on my old Sony a900 DSLR.) Now THAT is a noisy-focusing lens! It uses the old screw drive focus method. The noise doesn't matter, of course, for stills, but it is very noticeable for videos.
