    Hello all. Still learning about my camera but I don't know if I'm opening a can of worms here.

    Once I've finished with my camera, is it best to take the lense off and put the caps back on before putting it back into my bag or leave the lense on and put it in my bag.

    I know it can attract dust by keep taking it on and off so just looking for pros and cons into both..
    Cheers.

    leave it on unless you having a battery issue, i think there are some adapters and maybe some lenses that can cause that but i have always left the lens on ready to shoot.
    i bought the 22mm efm to replace the body blank when i first got my M50, then used my fav lens after that at the time to keep on the camera.
    now after a days shoot i put the 32mm 1.4 efm on even if it wasnt the last lens i shot with, generally its ready to shoot indoor or out door with its 1.4
    also its alot easier handling to down load images swapping from a 400mm to the 32mm as i just transfer via wifi, never take the card out the camera, its been in there a year and half except a few times my gf used it for vid and used d&d for vids.
    never formatted it either, sandisk 64gb.

    the other way of looking at it is if you are just removing a lens to park it you are un-nessecerily giving an opportunity to let dust into the sensor box, especially if you just putting the same lens back on again.
    thats my opinion, not necessarily the right one but i've had no problems with it

    Agreed, I would suggest minimize lens off only to necessary lens swaps to avoid unneeded dust. Also I always make sure to power off an let the camera sit a sec to avoid static cling of dust as well as I point the lens down and swap quickly. But to be fair these habits started way back when I got my 20d back in 04, cameras tended to be huge dust magnets back then.

    yes i prefer to do it with two hands, one off one on, its the only time i attatch the original neck strap when i'm changing smaller lenses, normally stand the bigger ones on their fronts with the hood on and have the camera always pointing down as i swap.
    the old vintage lenses you have to watch, they can have a bit of dusty dry crap inside them waiting to fall onto the sensor the number of years they lived, i know you shouldn't but i blow out my vintage lenses with an airline at the rear, on the czj there was a bit of dry stuff come out.
    if i do blow anything into an old vintage lens they are pretty basic to strip and refit.
    i never do that to a modern lens ot camera, just the rocket hand pump if needed

    I find that there is a lens that I use more than any other lens. So this one is pretty glued onto the front of my camera. Once I have finished for the day, the lens gets left on the camera.

    which lens is that for you at the moment Gary
    the "fav" lens changes over time as we get different ones or we get into shooting a certain style for a while.
    these days its my efm 32mm ƒ1.4, its a good all round lens ready for day or night/indoor shots,
    before that it was the 18-150 efm

    The EF 70-200mm f4 IS L. And it has been for a couple of years now. An easy 90% of shots are taken with it.

    I agree with that. There are a couple of used 16-35mm F4 L going at the local camera shop at this very moment in time. I have been tempted more than once to buy one, and see if that would make me put the 70-200mm to one side for a while. 28mm is the widest I have ever used or owned. Stop laughing.

    I love a fast prime. I have a Sigma 40mm f1.4 I brought for low light stuff. And I see that the center of the milky way is just starting to rise above the horizon not long after night fall.

    When I was using Pentax, the Sigma 18-35mm f1.8 was my go to lens. I still own it, and the camera, but I have leant it out for now.

    excellent, i can blame you for not trying hard enough :)
    its probably because when i been looking for new lenses they been at one end or another of a spectrum (more on that later) so the canon versions tend to be out of my price range.
