I use a 22mm f/2 pancake len "around the house" ... outside the house usually something longer www.flickr.com/photos/mmirrorless

I understand I am "obsessed" with sharpness yet, the 50mm 1.8 ($60) seems pretty sharp www.flickr.com/photos/mmirrorless

those are your only two options?  seriously ? dude,,  do you realize the 40D is a ten year old camera? even if you could find a 40D it should cost ....... $50 ! For hiking and mountains and small ...

if you primarily shoot portraits look at large aperture primes - 85mm 1.8, 100mm 2.8, etc

I don't care about megapixels but AF speed is good for video.   heck, if you're making money from vlogging and videos get them all - lens and cameras

gotta check out that G7X www.flickr.com/photos/mmirrorless

since all the Canon lens work with "M" I'd get the 22mm f/2  ... but I already go that lens!

if you have absolutely no lens with the camera then get the 18-55 STM for 2 meters the 50mm 1.8 may be better ($89 refurb) but if you have no experience start with the kit lens

yes, better lens like the 85 1.8 could help but more importantly learning about photography would help much more such as proper shutter speed, 'DOF' - depth of field, and using diffused lighting, ...

2 weeks 4 cities 18-135 STM - 10-18 yes, get the the 55-250 www.flickr.com/photos/mmirrorless

.... yeah ....  the "operator"  -  the person behind the viewfinder .... can be a problem with photo quality !

if you're primarily shooting video then a Panasonic video camera might be better,  the newer Canon 80 and Canon M5 are better than their predecessors but maybe not as good as a dedicated camcorder ...

yeah, either you got a bad 55-250 or ......  could be bad 'operator' !

yes, if studio strobes = external off camera flashes

riiight ... two cameras in your 'big' pocket, full frame lenses and a cell phone, and a wallet. pretty soon you're be walking around with a big purse ! www.flickr.com/photos/mmirrorless

I use my old 430ex II on the M - works great

I think you're going to be switching lenses, the 60mm 2.8 and 100mm are good for some shots and will certainly be better than the old Sigma 17-70 (move back for the wider shots !)

"private purpose, travel and holiday camera? just get a mirrorless model camera with 'pancake" style lens www.flickr.com/photos/mmirrorless

nothing is better than the Canon G7X ?   ...... didn't realize it was that good www.flickr.com/photos/mmirrorless

could be an issue but look at all the mirrorless cameras www.flickr.com/photos/mmirrorless
