No E shutter requires you to be operating in live view. If you want viewfinder shooting and E shutter you need to go mirrorless.

I would have walked further along the south bank from Canon street bridge to Tower Bridge (with a very distinct, iconic shape, framed a similar shot but got lower to be more in line with the dog ...

You might find a used 100-400 F4.5-5.6 Mk II Used for $1800 which is a bit more than you intended to spend, otherwise do what Graham suggested.

Some of the shots are quite noisy at full resolution (despite ISO160) whereas "Thunderbird Climbing Out" is not. Have you cropped heavily and enlarged some images? Have yo applied global ...

No you are not making a mistake, but also consider a used 5 DS-R if your use is primarily landscapes. The DR of the 5DS-R is between the 5D iv and the 5 D iii, but you have 50Mp of resolution and ...

The bushes just past the foreground rocks are in focus which must be only 50m away so @F4 I would be surprised if the plane of focus is as far away as the dark pines to the right of the buildings. ...

This dust is absolutely nothing to worry about. Regards Mark

Thanks :) Taken in the Knidos ruins at the very southwestern tip of Turkey.

These two were taken with the 100-400II but with a 5D4. I think I used spot AF for the focus point and SERVO AF as the subject distance varied as I could not stand perfectly still. If this does ...

For an unprocessed 1000 ISO image the noise looks typical and mostly luminance noise which is less offensive than chroma noise. It certainly can be improved with some noise reduction which you ...

You could buy a second hand 6D Mark I for around £450 which would give better quality video without autofocus - do you really need autofocus anyway ?

Why would you need a new lens, just adapt the lens you have got. An R6 is £2400 in the UK £2200 grey import. You would downsample 4K footage to produce the best HD result (which I thought was your ...

The 6D Mark II has unfortunately only low bit rate HD formats losing the All-I format the 6D Mark I had. Maybe rent an R6 and see if it is more to your liking with 4k options galore?

Total long shot but check AF menu 4 : lens drive when AF impossible is set to ON

Sounds like a 100-500 could also solve your problem if you can live with the smaller aperture at 500mm: no more lens swapping!

By service manual I presume you don't mean the regular instruction manual but something to guide you disassembling and reassembling the camera?

Here's a blossomy one!

or no bands if the anti flicker synchronized the period of light capture perfectly.  A big if.

The ultimate would be a transparent sensor onto which information could be displayed  that you could look through thus having an optical viewfinder, that also recorded photon data when taking a ...
