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.

”Too slow?” Please explain how you know this to be true.

Actually, I did some research and it was summarised here . But, it is subjective. Note, the OP was talking about 600D.

You are right about one thing - it is subjective.

I first got my 24-105L when I had a 600D. Up until recently (apart from my ill-fated Sigma 17-50 f2.8) the fastest lens I owned was probably f3.5 and that was only only for the first few mm of the zoom range.

Sorry to burst your bubble and dispute your "research" (not that your linked thread to which you got a single reply qualifies as conclusive research) but I have been using lenses that were "too slow" since 1991 then. I have used those lenses for museums, night photography, aquariums, green houses, botanic gardens, weddings, family functions etc etc.

Did I sometimes wish for a faster lens - of course I did. That is why I now have a 22mm f2 for my M5 and 35mm f2 IS for my FF. I still use my "too slow" zooms far more often than the faster primes.

To say that f4 is too slow for a 600D is a very broad sweeping statement that is somewhat misleading. It is like telling someone that anything other than a f1.4 prime is useless. If a person is buying a lens to use specifically on a 600D (or most bodies for that matter) for indoor functions without flash, then I would agree with you, but I don't think this was ever implied.

For most people a general purpose lens is exactly that and has to cover a large range of functions, and there is almost always a compromise - that is what photography is all about. If someone could make a reasonably priced 11-150mm f1.4 lens the same size and weight as a 24-105mm they would make a killing, but I think it is somewhat unlikely.

A bit like your misleading statement that third party lenses are fine if they are fine-tuned - also not accurate, and especially so on a 600D that has no facility to fine tune any lens, third or otherwise.
