I couldn't be happier with this pack. I was able to fit both my Canon and my Pentax cameras in the bag with 7 lenses, cleaning supplies, a 10-inch tablet, extra batteries and a rain cover for my cameras. My laptop fits perfectly as well as my tripod. I even had room for snacks and a water bottle for those long days hiking or working the scenes as a photojournalist. Definitely a great buy for anyone.

This adapter did the job! I can now use all my Canon, Tamron and Sigma lenses on my new Canon m50.

It may fit some of the Sigma lenses, however without the automatic focus.It focused easily and perfectly with Canon lenses

For the price, it can't be beat. If you're using it for something heavy, you'd probably want to spend more. I'm using it for a Pentax DSLR camera. I'm not using lenses that are too big. I did some night shots of the sky/forest and they turned out great.

Why i first went with the Sigma 35 i have no clue! Ended up getting this one after my sigma took a fall and was getting repaired. I know am selling my Sigma 35m because it can't compete with the canon version. Its worth every penny.

Reading most of the reviews here you'd think this bag was small and not good enough to carry your larger DSLRs. Here's what I can fit in mine:Pentax K-1 DSLR (pretty big)Pentax FA 20-35Pentax D-FA 28-105Pentax DA* 55mm f1.4Pentax FA* 85mm f/1.4Another smaller size lensJoby Gorillapod SLRSpare battery, cleaning cloth and a flash unit, and maybe a screw on filter set in the mesh compartment.They all fit in there very nicely - a bit snug but definitely do-able. The zippers are reliable and I've not had any issues carrying the above. Ignore the guys that want to carry their huge zoom lenses with the DSLR attached - they can spend a bit more to get what they want. I'm happy to remove my lenses from the camera.

Sigma makes great lenses and horrible caps. Both 35 and 85 lense caps wouldn't stay on. This one goes on and stays on. Looks good with my Sony camera too!

These work well with my Sigma and Nikon lenses and lens caps as long as they are stuck to a flat part of the lens cap. There is a little bit of thickness to the foam adhesive, so the surface doesn't have to be perfectly flat. Just be sure that the surface is clean and you press and hold the adhesive down for 30 seconds or so to ensure a good seal.I haven't tried to remove the adhesive side so I can't rate that, but the elastic works well for the Sigma Art 18-35 mm and Nikon 35 mm and 50 mm lenses.
