smorgasbord: Just confirmed that the autofocus in movie mode is disabled when shotting at 59.94 frames per second. A bummer, and I can find no mention of it anywhere online. Yes, you can press the AF ON button to focus while shooting, but you're not getting the tracking AF that this review touts so highly when shooting at the faster frame rate. I'm sure there are technical reasons for it, but it's a bummer for my style of video shooting.
Sounds like you need an actual video camera. Make too much sense?
wilde: Most reviews of the Canon Canon 24-70mm f/4 L IS lens are not complete and much to positive. I hope Depreview will give us better and objective test results. This lens suffers from a severe obtical problem.When (with manual focus) stopping down, the point of focus shifts backwards, see file below. So, if you use a tripod and try to make a portrait you need to focus again when stopping up or down.I hadn't expected this problem in such a costly lens. Not a lens for canon to be proud of.
U should learn how to use AF. Its 2015 now.
sportyaccordy: How is the dynamic range....
You might consider a career in stand up comedy!
Birtrum: I purchased an SD1 for my business of photographing textiles in a studio situation and I feel totally deflated. The actual image quality is excellent, but the tethering capabilities are pathetic. I expected to be able to click from my PC to launch a shot, then instantly see what I had taken, before moving on to the next item, which sadly is not the case. Their software application known as Sigma Capture Pro should be reported to the trading standards council, as there is nothing 'Pro' about it as it is just a glorified remote shutter release program. Furthermore in order to have access to your images on a PC, you need to go into the menu function on the camera and disable the 'remote capture program' then select mass storage to view your images. Going through this process with every shot, may be good for you cardiovascular system, but for someone who relies on seamless throughput to make a living, this camera is junk.
Tethering capabilities? lol. You are more interested in showing off in front of clients than achieving great results. Re-align your priorities. You do realize that 90% of the time the images are used at 400 pixels wide on a web site - do you? you don't need to check each shot at 100% mag on a full size screen before you know you got it. Give us a break with your grandstanding.
Birtrum: Is this the 24-70 ART lens that you are using ? I have the 28-80 HF and 18-50DC's but the Chromatic Aberration is shocking with these and I cannot achieve a constant colour, without discoloration around the edges. I was thinking of buying an adapter and looking for a better lens, possibly a Nikon one.
Use a full frame lens like the 24-70 F2.8 EX DG HSM. You will get fantastic results. Use it properly - on a tripod at 100 ISO and F8. Have good light. Shoot raw. Convert to 48bit tiff. Edit with the appropriate skill. If the results don't blow you away, your doing something wrong.
I already have a 24-70 F2.8. So why would I want a 24-35 F2 exactly?And please don't say for the extra stop of speed.With Image stabalization and clean 1000 ISO these days, my shutter speed is plenty fast enough?Seems ridiculous to me.
Rawmeister: I'm generally tired of trying to judge image quality from photos that have a depth of field of about 3/4 of an inch. Please stop doing that.Shoot landscapes using 28 or 35mm at f8 please. Thank you.It's image quality (sensor resolution and dynamic range) were want to judge, not techniques to get 3d effects using blurred backgrounds. Let's stay focused people.
Use a tripod next time please.
If you shoot at 400ISO or less, use the best lenses, shoot raw and use the latest version of the much improved Sigma raw conversion software, you will be able to upsize your clean artifact free files to around 6700 pixels across giving you an equivilant resolution of a 30MP Bayer sensor. I do this all the time and the results are fantastic. Using a full frame lens on this sensor gives you images that are sharp to the corners and almost distortion free. The 24-70mm F2.8 HSM on this sensor enables image quality way beyond anything I ever shot on a 5D2 or 5D3 with L lenses.. When you get to know the tool and develop skill to use it well, the results will blow you away. Most people want it easier than that. You reap what you sew!

very disappointing results from both the lens and the sensor.
testing lenses at iso 2000?? whatever - sheesh.
techjedi: Hopefully this will reduce the price of traditional coated lenses.
You tried stand up comedy yet?
Who needs it ? - I mean seriously.It's just another attempted wallet emptying exercise - hohum.
Imakefoto4U: A rectilinear 11mm Canon L lens plus zoom to 24mm is something I have been waiting for. I have all the wide Canon Zooms and only the 8-15 is wide enough but it is not rectilinear. The expense and weight will be ignored if the results are superb.
maybe you should consider the 14mm. Much more practical, lighter, cheaper, faster, wide enough and very sharp. You could even get a used one. Not saying anything. Just saying.
