  1. I don't follow the APS market, but I'm curious. Since the APS cameras aren't really that much smaller than the full-frame cameras, do you think that Sony will continue with the APS format? Apparently other camera makers are sticking with smaller sensors, but Sony seems to be headed toward the 24x36mm sensor size and e-mount only. Am I wrong?
  2. One thing to keep in mind in this ZOOM world that we live in, photographers who want PRIME lenses want them for better results and better features than what zooms offer. That usually mean special glass, faster apertures, more features, greater size, greater weight and higher prices. The manufacturers are happy to offer these lenses, of course, but they tend to be offered in only certain focal lengths. What you're looking for might not be available because there is not enough demand for it. People are attracted to the APS format because they think the cameras & lenses are smaller and lighter -- and the prices are lower. This has an effect on what the manufacturers manufacture and market. What you want may not be available. You might need to compromise to get what meets your needs -- like a larger full-frame zoom. And you would not be the first AF photographer who opted for a manual-focusing lens because what they wanted was not available in an AF lens.
  3. That guy is kinda correct, but I agree with Pieter -- the way he is presenting it can be confusing. As Pieter suggests you need to think APS format when thinking lenses -- not FULL-FRAME format. The exact same thing applies to 35mm full-frame cameras and half frame cameras. A 50mm lens is consider a normal lens for a full-frame digital or film camera. If you put the same lens on an APS or half-frame camera it is still a 50mm lens, but the sensor only sees the central section -- so what you get is a cropped image, or longer focal length effect. You would get the same effect if you used a 75mm lens on a full frame camera. So if you want the same normal lens effect of a full-frame 50mm lens on an APS or half-frame camera, you need to use a shorter focal length lens -- such as 30mm. It's easier if you think APS format when thinking of focal lengths, and not FULL-FRAME format -- although people who use both APS and full-frame cameras get used to it. It sort of like speaking French and Spanish -- similar in some ways, but not the same.
  4. As I alluded to before, there just does not seem to by many (any?) APS-C e-mount PRIME lenses in the 135 - 180mm range. Maybe there are some that I don't know about. Even if you expand to 100mm and 200mm, they all seem to be FULL-FRAME. I don't quite understand that myself, but I'm not an e-mount kind of guy. Samyang makes an 85mm f1.8 in APS-C e-mount. And apparently my suggestion of an ~85mm with a tele-converter is a "non-starter".
  5. I don't quite understand this. Why send us a photo that's different from the one that you say is problematic? Also, since you are using such a high shutter speed, why not just lower the ISO? How you run tests are other ISO settings? Does it still happen? And why not use HIGH IEO NOISE REDUCTION?
  6. I assume this means you are using the same shutter speed and f-stop. What was the shutter speed that was used? Did you both use LONG EXPOSURE NOISE REDUCTION and/or HIGH ISO NOISE REDUCTION? -- assuming your camera has these.
  7. You don't specify what camera(s) you are using, but in the 135-180mm range of PRIME lenses, there are about 1/2 dozen A-mount and about 1/2 dozen E-mount lenses to choose from. They are all 135mm with apertures from f1.8 to f2.8. They are all full-frame, so they are not going to be small. The early Minolta 138 f2.8 might be the smallest. You could go for a shorter focal length with a 1.4X or 2X converter, but I don't know how much that would save you in weight, size, cost, quality, etc. Another possible option is the Minolta 100-200mm full-frame in A-mount.
  8. Hello. I'm sure you will get some suggestions from people on this Forum, but this Forum targets users of Sony cameras with interchangeable lens (a-mount and e-mount). The two cameras that you mentioned have non-removable lenses. You might get more helpful responses if you ask on a Forum that deals with Sony's DSC cameras -- and has more people who have used those cameras.
  9. The easy way is to just give it a try. Different cameras have different connections, so just try what you've got.
  10. I think that depends on the camera. On some, that socket is just used for playback/display purposes, but on others it is used to connect to a computer -- for display and camera control -- so it might work. Do you have a manual?
  11. When I'm hiking, weight -- and the nuisance of TWO cameras around my neck -- mean just one camera and one lens. But I usually have a pack as well. If you are comfortable with two cameras, I'd use the A7RIII for the animals so you can crop. Otherwise sell the A7III and get another A7RIII -- or get used to swapping lenses.
  12. Asking for advise anywhere -- especially on the WEB -- can be tricky. The first obstacle is getting your request crystal clear to strangers. And when it comes to GEAR, it can be especially dicey. Everyone has their own approach. Mine is always use what you have -- it's a LOT cheaper and probably just as good. Soooo, much of what I say/advise is immediately dismissed. That's OK with me. Water off a duck's back. So it goes both way -- asking for advise or giving advise. Be prepared for the unexpected responses. "Take what you like, and leave the rest".
  13. Just a thought. Why not contact an authorized Sony repair facility and show them a copy of the five year warranty? And start a new thread on "How long is YOUR Sony warranty?"
  14. I'm not in the "trashing you for using the camera", but before you send it off, you ought to take the time to see if we can figure it out. How about answering my earlier question: So the camera has the exact same problem when powered by the AC cord -- without a battery installed?
  15. So the camera has the exact same problem when powered by the AC cord -- without a battery installed?
  16. Since it's ON for 8-10 hours per day, I would assume you use an AC adapter, but you have only used batteries, correct? My first thought is that the batteries are simply worn out. They can only be recharged so many times. Do you have an AC adapter? Have you tried a NEW battery? Do you somehow know that you will get better service from Nikon or Canon?
  17. We'll need more information in order to help. Has this camera been ON for an entire year 24/7? Has anything changed lately? Moved? Dropped? Different lens? Settings Changed? I could go on. Right now, we have nothing to work with.
  18. The terms "macro", "ultra macro", etc. are meaningless. There is no legal definition, and companies use these terms to sell you their stuff. You need to think about "magnification". How much do you want. If you want to photograph things that are 1.5" in size, that's 1X. If you want to photograph things that are 1/4" in size, that 10X. Figure out how much magnification you want, and then look for gear that does it. Better yet, read a book, such as: Manual of Close-Up Photography, 1979 by Lester Lefkowitz And Pieter is correct, you don't need auto-focus for high magnification situations. I use Minolta Rokkor-X and Tomioka Tominon bellows lenses -- on a bellows, of course -- and get superb results. You can spend an arm and a leg if you want -- and still get crappy results. It's more important to focus on technique. Check out: http://photocornucopia.com/1061.html
  19. And with a tele-converter, auto-focusing will be slower -- sometimes much slower -- assuming it auto-focuses at all. This may be due to the lower light lever -- maybe not. Apparently a lot depends on the lens and the tele-converter, too.
  20. I would think that the A7RIV would be all perfectionist would want. None of the other cameras comes close to its pixel level. Getting an A9II or A1 would be a step down in that regard -- although they might have features that are more important for you. Do you have a problem with your A7RIV? If not, maybe sell the A9 and A6600 (or keep one as a backup), and buy some better glass for your A7RIV.
  21. No need to shut up. I'm a firm believer that "you CAN teach a young dog an old trick!"
  22. You're walking on thin ice here. Next thing you know, you'll be suggesting manual exposure too!
  23. You'll get a million responses to your question. Much depends on much much you want to spend and what's important, like is weight very important? Get an all-in-one lens like a 24-200mm. Weight, price, and ease of use not so important? Get two lenses, like a 17-35mm and a 28-300mm. Got even more money, get three lenses, etc.
  24. Did you run the tests that I suggested (above)? What did you discover?
