Third party lenses are fine if they are fine-tuned.

User Experience of Sigma 17-70mm f/2.8-4 DC Macro OS HSM C

a canon 24-105mm f4.0 "L", preferably refurbished by canon to save money! this is an excellent range lens for walk around and daily activity with high IQ, much better than ef-s lenses, and someday when you upgrade to FF camera, 24-105 will fit nicely. i personally stay away from 3rd party lenses due to sometime AF compatibility with canon cameras! YMMV.

Not all of them. I had a Sigma 17-50 f2.8 that was just inconsistent, so no amount of AFMA would help - sometimes it got the focus right, other times it didn't.

From what I can tell, this is not a particularly unusual experience with Sigma lenses on Canon. It doesn't affect all lenses, but it certainly affects a lot Sigma lenses than Canon lenses.

The point is that F4.0 at 600D is too slow. It is equivalent to F5.6 at a full-frame camera. It is almost no use for locations such as museums, aquariums, botanic green houses, and streets in evening. There are not many Canon relatively fast lenses for their APS-C cameras.

this shot proves your theory wrong! i used my canon 17-40 f4.0 on my 40D, f6.3, 1/20 shutter speed! this was a pretty dark spot, dark as ambient light of a museum!. sounds like you don't have or used an f4.0 lens on a aps-c camera. i have numerous shots to prove you wrong:

Good shot and kudos to you.

Can you show me something with your F4.0 on 40D like that:

As I explained here , the old 18-55mm f3.5 - 5.6 IS struggled and I wasn't happy with those primes. I wished I could have a lens a bit wider.

it is a beautiful city escape concept but unfortunately, the focus is horrendous when enlarged! it is good for 4x3 size print but not any larger, IMO. you could use a heavy tripod and a remote control shutter release, or the stability of my hands (my posted shot was taken with 1/20sec shutter speed, handheld) i will try my 17-40 f4.0 for city escape to see how it turns out, and if good, i'll post it for ya!

Sure, I look forward to yours.

My one was take at Tsim Sha Tui of Kowloon to Hong Kong island across Victoria Harbour, 500 meters away, handheld of course.

Use a heavy tripod when travelling internationally? I hope your are not joking.
