The “R” in this camera line stands for “resolution,” and the large sensor in the a7R IV took a lot of processing power.

The a7iii is still a great camera, especially for the price. I've thought of getting a second body for gigs. As for lenses, you can get the Sony 35 1.8 or 55 1.8 are both super sharp and can be had used for $400 or less. I own the 35 but almost bought the 55 (ended up with the Sigma 65mm, which is also a great option).

A7R - R for resolution - high pixel count - think landscapes, large prints. A7S - S for sensitivity - video oriented, low pixel count. A7 - general purpose - capable of most things, but not a specialist.

Sony α (the lower case to Greek letter alpha, often transliterated as Sony Alpha) stands as a prominent digital camera system and consumer DSLR/mirrorless camera brand.

The Bottom Line The Sony a7R V takes everything photographers loved about the a7R IV and makes it a little bit better. Faster, smarter autofocus, a gorgeous EVF, and a clever dual-hinged display make it our favorite high-pixel camera.

Even if the AI-powered autofocus is that good, the Sony a7R V is much too slow for proper action photography. Unfortunately, no other camera has this sophisticated AI AF system yet. If you're a landscape photographer, the resolution is great.

Taking everything into account, professionals mostly use mirrorless cameras made by Nikon, Canon, or Sony. No matter if you are a professional, a beginner, or an amateur photographer, whichever camera you do choose, don't forget to enjoy the process!

Marketed as an entry-level mirrorless model, it boasts fewer megapixels (24) and isn't as fast at shooting as the Sony A7R III or A9, though it can handle weddings, wildlife photography and casual filming. Does that mean the Sony A7 III is good for beginners? Absolutely.

The Sony α7, α7R, α7S and α7C (the α is sometimes spelled out as Alpha) are four closely related families of full-frame mirrorless interchangeable-lens cameras. The first two were announced in October 2013, the third in April 2014 and the fourth in September 2020.

Image quality The “R” stands for resolution and aims at photographers who can make use of such a high resolution, whereas the “S” stands for sensitivity and aims at users who need good image quality at high ISO for stills and video.

alpha value sets the face transparency for objects in the current axes that support transparency. Specify value as 'clear' or 'opaque' , or as a number in the range [0, 1]. A value of 0 makes the objects transparent, and value of 1 makes the objects fully opaque.
