1DX Mark III

[Joel Eade]

Using a 2X TC is a lot of fun and the 1D bodies are amazing, I still use my version 1 for family outings mostly with the 16-35mm f/2.8 set to shoot small RAW files. I usually employ TV mode 1/800 sec and auto iso which assures sharp pictures with decent exposures no matter who picks up the camera and shoots. The smaller files are easy to process and they will make good prints up to 11x14. I think you could fill a card and it would never hit the buffer limit. The sound on high speed is fun.

A few more features I found on the R5 and 800mm f/11:

Exposure Sim: both on the LCD and in EVF you see what the image will look like based on current settings

A histogram (either brightness or RGB) can be set to display live on the LCD (but not in the EVF)

Crop Mode: 1.6 crop mode with 800mm f/11 gives the field of view similar to a focal length lens of 1280mm and yields 17 mp images (very nice for small birds). No TC needed!!!

Bluetooth: using the Canon camera control app and a smart phone you can remotely control the R5 .... aim it a perch and wait ... when bird is in position just touch the phone and it fires away .... lets you hide better and much less motion involved. Also no cable release needed!!!

Shutter noise: the mechanical shutter is very soft and the electronic shutter dead quiet....so that satisfying machine gun sound is not available. The mechanical shutter is not near as fast as the 1Dx3 anyway.

Flash: does not function with electronic shutter

Control wheels: there are 3 .... the front one and big rear one as usual but another one around the mode button (set to adjust iso by default) They are all programmable.

The 800mm f/11 does not come with a lens hood ... bummer.

The LCD is articulating .... it can be folded inward against the body so no way to scratch it during transportation.

The LCD is a touch screen and almost everything can be adjusted by this method. Also it responds to gestures like an i-phone.

The large files from a full frame shot are slower to process of course .... my 2018 MacBook Pro will often turn on the fans during processing.

No issue overheating at all but I have not shot video

No issue with battery life .... I shot for 2-3 hours yesterday and still had 1/2 battery power left. I did set the LCD and EVF to turn off in 1 minute.

That's the latest news from my perspective.
