The EF 400 f2.8 is one of my favorite lenses and it ALMOST let me down yesterday at football. I typically shoot football with three bodies and lenses (1DX III bodies with 400 and 70-200 f2.8 glass and 1DX II body with 24-70 f2.8) and as I was settin...

Every season has to come to an end and the team I shot for went out in the quarterfinals but not without some athleticism. Shot with Canon 1DX III / EF 70-200 f2.8 @ f3.2, 1/1600, ISO 640.Rodger

Football is a game of inches and in the pouring cold rain and wind, this was about a finger inch short of a completion. Captured with Canon 1DX III and EF 70-200 f2.8 IS III @ f2.8, 1/1000, ISO 20,000. It was a miserable night for football and phot...

Canon's EF 400 f2.8 telephoto prime isn't typically used for portraiture but I couldn't resist making a quick capture of this expression between snaps during Friday night football last night. Shot with EOS 1DX III and EF 400 f2.8 @ f2.8, 1/800, ISO ...

The shutter assembly on a pro body is just a maintenance item and is replaceable at a fraction of the cost of the body. Even after Canon refuses to service it, other places will do so.1DX series bodies are extremely rugged (I have a pair of 1DX II a...

This lens series has a design/build issue with an internal cable and when it fails the lens will generally only work at wide open aperture and this is generating the error message. Canon repair is about the only solution, a lot of used 24-70 glass f...

Megapixels are a measure of how many photo receptor sites there are on the sensor while megabytes is a measure of file size, the two aren't the same to start. AND saving as a jpg will result in a smaller than initial file size in megabytes because t...

A 2-56 has a slightly larger major diameter (2.1844mm) vs a M2 (2mm) so your original screw is probably a M2 but it might be a M1.8 so check with calipers or a chart.This may be a good application for a heli-coil insert, those are available standard ...

I agree with John that any shop can determine the thread spec of the current screw AND determine whether tapping to a slightly larger size or drilling to install an insert works best. If the lens is otherwise still in good working condition, I would...
