Hello all, after about 2 years of no use I decided to dig out my old 40D for a bit, however it will not turn on, at all. I have the only the original battery (so yes it's about 14 years old at this point) which, when put in the original charger, will appear to charge as normal going through all the light-flashing stages. However the camera does not respond with the battery at all, not so much as a flicker on any of the screens (and I ensured all doors were firmly shut).  Before I start...

I am trying to find out if current Canon cameras will let me set the Aperture I want AND the shutter speed I want, then automatically set the ISO for correct exposure. I think Pentax call this TAv mode. My old 40D will not as AUTO in Manual mode sets to 400ASA. You have to fiddle around to manually set the ISO, by which time the wildlife has gone. When using my long  lens to shoot wildlife I want to be able set about 1/500 to avoid shake AND perhaps f8 to limit depth of field, then I would...

Hi guys, I'd really welcome some advice/help here, my knowledge of photography is very basic, and this is driving me nuts! I'm struggling with my new Canon EOS camera. I upgraded from an old Canon EOS body to a 2000D and even though I have copied the settings from my old camera  (I think) , Im getting images that are very dark. I use the camera at work for patient photos, the setup recommended to me is: Sigma ring flash and macro lens as in photo Camera set to AV, custom function force 1 /200...

I'm trying to use my Canon 40D to live stream dance classes. I have it connecting to Zoom via Cascable Pro on my Mac. The only thing that isn't working is autofocus. I have followed these instructions ... https://www.cameraexperts.us/canon-eos-40d-guide-2/using-autofocus-with-live-view.html ... But when I get to step 4-5, the AF ON button does nothing. If I unplug the USB cable to my laptop, the AF ON button will work. What other settings or software do I need in order to stream a video with...

Back in the day I took pictures with a 400 mm t-mount lens and a 20 d set on aperture priority. It worked fine.  now my son has taken to photography with a 40D I gave him, and I want to give him that lens. So I ordered a t mount with a focus confirm chip. The focus confirm works fine, but aperture priority does not. It has been ten years since I did this and I assume I am forgetting something. Any suggestions as to what it might be?

Ok. I finally got fed up of paying each month and have been trialling various other software. I have been using Lightroom and Photoshop. I do love the way photoshop works and ideally I'd like something as close as possible. However I have always hated LR. I used to use Picassa 3 for cataloging, and I've yet so see any software that is as intuative. So. Is there 1. A one-stop-shop that will help me organise and give me PS-like functionality. Or 2. Is it best I grab a DAM and an editor? I've a...

I bought the 40D when the kids were in high school. Used it alot for their Team sports. Life got busy and I got away from my hobby.  But now I have a little more time and would like to consider re-engaging.  I have Canon L Glass circa 40D time. I was thinking of upgrading the body.  If you were going to spend 500 - 600 dollars on a used body, what would you consider?  I have been out of the game for a long time. I appreciate your help. ---Vernon

So I picked up a used 40D for cheap and I’m assuming this isn’t the default focusing screen. The center part around the circle looks drawn. My question is: what would this focusing screen be used for? Are the lines guidelines for cropping to different aspect ratios?
