Weighs just as much as a 35L + 85 1.8 combined!

hi,

I'd like to start a thread about people's experience with this lens

You didn't say on what body the 24-70 will be used?
You should expect it to be sharp at all focal lengths f5.6 and onwards.
You should expect it to be softer at 24 and 70mm at f2.8. Don't be alarmed thinking it should be equally sharp at f2.8 as f5.6. At 24mm there is some barrel distortion and field curvature.

Its an excellent mid range zoom, a very useful focal length on FF or 1.3 crop, I used it as my main lens for many years.

I'm not too impressed with this lens on my 7D. But hopefully I will be on my 5d mk ii.

In what way ? I have owned 2, first one backfocussed terribly, sent it back for calibration and came back ok. That lens was then stolen and I just received the replacement yesterday, first few shots seem to be fine but not had time for extensive testing yet. Backfocussing seems to be a pretty common problem with a few of these lenses so check that your isnt one of them.

Firstly, it isn't as sharp as they claim it is, but maybe that's because it's being used on a crop camera. The overall image quality doesn't impress me at all for an L lens and I've tried it with all different kinds of settings.

It doesn't back or front focus so much but my Canon 50mm f/1.4 definitely does. Especially if I try and focus it manually... my god.

I talked to mine once in a while and sometimes it does give me back some good images.

Mine is sharp on 5D2.
Tip, follow the minimum shutter speed vs focal length (x 1.6 on crop) as it does not have IS.

I think the 24-70 is about as good as it gets for a mid-range zoom, just very heavy and must have a steady hand. I don't necessarily think there is a steep learning curve to use this lens, just takes some time and experience to get the best of it. It's no point & shoot lens.

Best tip is to use the hood to protect it. And to get a workout to get used to it.

I wont rave about the lens. It simply works well for fast paced events. Wideopen it lacks contrast but when you have a perfectly calibrated copy (sent my to CPS) its now tack sharp wideopen.

I use the spider holster with my gear so weight is not an issue. I use to lug a 1dmk3 with 70-200 for 8+ hours with no complaints.

For me the 24-70L was a basic lens with no special requirements in "getting use to it". It simply is a good red ring tool. My slower 17-40L f/4 lens produces much sharper/contrast photo at f/4 IMO but its a slower lens and different FL.

On a full frame you can get some nice shallow dof. All in all its a nice FL. I find it very useful in studio light situations since you stop down the lens and have versatility.

Just make an observation of back focusing when you shoot wideopen at 24mm or wide end.

If your focusing manually how can it back focus?

The "brick" is the only Red ring Canon has in this FL. Its long overdue for a mrk2 version to improve the overall IQ. If the 24-70L was even close to an older version of 70-200 f/2.8IS Mk1 I'd be extremely happy but unfortunately is far from that.

My copy is absolutely spot on and IMO almost good as it gets for sharpness wideopen. I wont ever sell it due to its versatility. The lens is notorious for back focus on the wide end when the aperture is f/2.8 or close to it. People just dont notice sometimes.

With the 5dmk2's iso capabilities I can get away with shooting no flash and use my camera like a big point and shoot :) IQ from my 24 or 35mm does a much better job but lacks versatility of a zoom obviously .......

Work out those biceps, cause you're going to need bigger ones to hold the "brick".
