Vintage glass is my latest obsession. There are cheap adapters available for any lens combo you can imagine. I put an old Leica lens on my Sony a7r and I’m getting some really striking cinematic looking shots. Even if you’re a professional there are endless opportunities for unique, creative images with vintage lenses.

This is not even remotely true. Sure they'll look much better on an oled (qled is not in the same league.. and it's mostly made up by samsung) but raytracing looks good on all panel types.

It's cutting edge tech for pc gaming, of course it's going to be for a small group.

Personally, I'm down for a foldable phone, just not from Samsung. I've never had a product from them that I liked, whether it was hardware issues or software (mostly software though).

Foldable, in my worldview, is the best of both worlds. Personally, I'd rather have a true phablet (which, in my view is a mini tablet sized phone, rather than the other way around. And the OS is tablet oriented, not phone oriented)

Yeah check KEH. I got one in pristine condition for like $500-$600 (can’t remember). Like it looks brand new and has less than 13k shutter actuations. For stills work you can literally create world class images with this sensor and the AF is crazy fast.

It’s older, but perfected tech and is built like a tank so if anyone is balking at paying $2500 for a camera it’s a fantastic option

Afaik, normal camera sensors acquire the image row by row from top to bottom or vice versa. I forget. So if you are recording video and sweep the camera left to right youll see that vertical lines like telephone poles etc will be staggered (stair-stepped) and have rolling shutter. But with a global shutter the whole sensor is captured at once and not line by line so when you shoot video and pan the camera vertical lines look straight. You can get over this by having the top to bottom scanning time be super fast (and this i think varies from camera model to camera model) or all at once like this new sensor.

It’s important for video, maybe high speed flash photography too.

CMOS sensors use a “rolling shutter”, where the image is taken one line of pixels at a time across the sensor. For video of fast moving objects this can distort the appearance and motion significantly. If you’ve ever tried to take a video of a propeller plane engine you’ve probably seen this effect. It can also cause the entire image to wobble back and fourth like jello if the entire camera is moving rapidly or vibrating.

A global shutter would have all of the image lines captured at once, eliminating this problem and making any high-speed motion look better in general.

Yeah exactly. a 5D3 is going to be more capable then most entry level photographers will ever need with proper glass.

I have a RP with some used lenses, I think I have $1500 total and it’s absolutely more then I’d need any time soon. the consumer class has basically died out anyway because of smart phones. you used to see people out and about all the time with $500-$1000 set ups, now it’s only people who are absolutely hobbyists or professionals, and they aren’t going to buy entry level gear anyway.
