+1 Ribbon cable(s) from mount to AF motor and aperture motor folds and unfolds as the lens is zoomed and can develop breaks over time. also, wrt "... everything is dimmer when I use the viewfinder ...

old design from the less critical film-era. More than that, it does not have image stabilization. The 70 -300's with IS are good (EF 70-300 f/4-5.6 IS USM) to better (EF 70-300 f/4-5.6 IS II USM ...

The speedlite must be mounted in the hotshoe for HSS.  The 50D's built-in flash cannot enable HSS in an off-camera remote speedlite. Also check that the 50D is not set for 2nd-curtain sync or other ...

looks legit to me. no original box or user guide is par for the course for this type of lens which was probably separated from an original camera+lens kit.

We also have 100D (SL1) and 4000D (Rebel T100), so how about Canon Rebel (EOS 100D-8000D ) Talk ? ;) "Rebel" brand is only North America. They're "Kiss" in Japan, but the numeric model name is ...

If you set the file type to RAW, then regardless of the WB set in-camera you still have the ability to override it to any other WB setting in post-processing.

There are many threads going back years and years on how DXOMark's scores are (1) unrelated to practical use and image output, (2) seemingly biased in favor ...

Correct. 430EX III communicates as a remote via optical light signals only. It is compatible with the non-RT model ST-E2 transmitter and other EX--- speedlites that act as master controllers using ...

?? Link ?? I can't find any confirmation of this.

Is it actually taking 30 sec. exposure and saving a pic? If mirror lock up is set, first press of the shutter button flips up the mirror (sounds like pic being taken), but doesn't open the shutter ...

+1 "old" FE 50 f/1.8 and "new" FE 50 f/2.5 G are Sony lenses. Maybe easily confused as Canon does have "new" (and old) EF 50 f/1.8 and "old" EF 50 f/2.5 (Compact Macro), and these are easily ...

?  The only moving parts in the camera are the mirror and shutter, neither of which would generate a whirring noise or be involved in autofocus. How old is the 7D's battery?  Maybe aged and not be ...

AF modes, pp. 79-90 of the 1D IIn instruction manual. http://gdlp01.c-wss.com/gds/0/0300002410/01/EOS-1DMKIINIM-EN.pdf That sounds like normal behavior for AI Servo (continuous) AF mode. Especially ...

Just laying out what you already know:  Rear lens in the EX EE and EX Auto cameras is 3 elements in 2 groups, so maybe Gauss by itself.  Suspect that paired with the EX 50 f/1.8 "front" lens (also ...

EF 35 f/2 IS USM is "ring-USM". Perhaps this tear-down of the ring-USM EF 35 f/1.4L USM II may help: https://www.lensrentals.com/blog/2015/12/canon-35mm-f1-4-mk-ii-teardown/

Assuming the "problems" and "playing up" mean shutter issues and you're otherwise happy with the output:  the cost of replacing the shutters on all 4 bodies (4 x $300USD) is less than or equal to ...

+1 re flare. I guess the samples use it to "artistic effect", but it looks problematic to me. YMMV.

78 is the bayonet mount diameter, so the hoods should be interchangeable on a lens that takes ET-78 (or EW-78 or ES-78) hood. ET-78B is the hood supplied with the EF 70-200 f/4L IS USM II. ET-78 II ...

A lens can only focus to a single distance. Anything nearer or farther than the focused distance is going to be progressively out of focus. You can extend the near-far range of items being in ...
