Went to the UHH Post You listed, Beautiful Picture of a Blue Jay, but no dialogue on teleconverters, so I went to your 500 Pix Page and all Your Photographs are Outstanding which speaks for itself,,,I agree a teleconverter cuts down on incoming light and the extra glass can cause less sharpness, and getting close, using bird feeders, or a blind or a tape recording of bird songs to get closer is better than using a teleconverter, still they come in handy in a pinch...and some of our Photographers on this forum have no problem with teleconverters but are generally using them on a very expensive fast aperture telephoto lens with a high resolution camera...

Sometime ago someone posed the question as to whether a refurbished camera had the count set back to zero or not. I bought my refurbished Nikon D5600 from Adorama with no info as to the shutter count. I just ran across a shutter count program that was simple to use and checked my camera's shutter count which was 311, meaning that this camera was either set back during refurbishing or had been refurbished at the factory before it was ever sent out for sale. This latter possibility was included in a comment on one of the NikonUSA website sections. By the way, the shutter count program I found and used is
"Myshuttercount.com". This site not only gave the count but it listed all of the pertinent info concerning my camera. I tried a shot from my point and shoot Canon but it didn't work. I don't know if the same type of data is attached to images from a point and shoot camera as is done with Nikon images but that could be the reason that the experiment was not successful.

Changing the subject, is there a UHH recommended pixel dimension/size for DSLR pictures attached to a post on UHH?

I need some advice. I pulled the GAS trigger today on a Nikon FF camera to replace my D7500. I'm not a pro. I shoot landscape, still life, and things that don't talk back. I have a full assortment of crop sensor lens, but no FF lens other than a 50mm/1.8. I bought a 24-85 f2.8-f4 Macro to go with the camera. If you had a limited budget, what lens would you get beyond the two I'll have? I enjoy milky way shots, light painting, macro stuff, flowers, waterfalls, and "artsey" stuff. Any suggestions are welcome. FWIW, I've have done two weddings (don't care for the pressure) and I've done a couple of office parties (free drinks). I don't mind manual focus lenses, used lenses, or refurbs if I can return if they've seen their useful life. Thanks for the help. I really do appreciate all the comments even they are a little painful.

on photo workshops I have been on I see some usage of ballheads with the long lenses; I am now using a Sony 100-400 on an a6400. Would like to hear from some who use these smaller / lighter setups ( as opposed to those of you truck around with a 500mm+ like a piece of artillery ). Someone responding to a previous query about gimbals was pushing a $472 ballhead; would like to hear from people who might have found more moderately priced ball heads. BTW, those I have encountered using a ball head absolutely swear by them.

Something I didn't see mentioned (and might have overlooked... I didn't read all five pages of responses yet)....

Your brother-in-law might also consider that he will need top-quality lenses for that 61MP camera. Those will be pricey, too.

Higher resolution cameras demand lenses with high resolving power. I don't know about Sony, but when Canon introduced their 50MP 5DS-series cameras, they also published a list of "recommended lenses". For the large part, those lenses were "the best of the best".... and also the most expensive.

And if you BIL doesn't make prints larger than, say, 16x20" he'll almost certainly never see any advantage to the camera and lenses. In fact, many people who bought full frame cameras are probably using way more than they actually need. Even then, look at "pro-oriented" cameras like Canon 1DX II and Nikon D5... they're 20MP and 21MP full frame.

Bigger is not necessarily better. Beyond a certain point, it's just a waste of money.

That said, lenses are more important than the camera they're used. I'd much rather have your APS-C 80D (24MP) with a couple really good lenses... than a 50MP or 61MP monster with mediocre lenses!

The idea to suggest he rent and try before he buys is a good one.

If he decides he's just gotta have the 61MP camera and is willing to also get the lenses it will demand... Here's an Apple Mac Pro and that can handle the files very well, I'm sure!

And he'd be able to enjoy the quality of the images on this:

He'll still need to get some software. And a printer?

Of course, he'll be the ONLY person who ever sees the full quality of the images, while viewing them ridiculously large on that monitor. He'll need to downsize them for printing or sharing online, after which they probably won't look much different to everyone else than your 80D's images.
