pilotdave 0 #2 November 19, 2007 IS is not useful for freefall. Not really necessary for wide angle lenses in general either. Really helps for telephoto lenses where a little hand shake will ruin a picture. It lets you use a lower shutter speed and still avoid the blur caused by a shaky hand. At wide angles, you can move the camera a lot more without affecting the pictures nearly as much. Plus, at the types of shutter speeds we normally use for freefall, image stabilization will have no real affect. But you can't really use it anyway, since you need to hold the shutter half way down to allow it to stabilize before you snap the picture. Dave Quote Share this post Link to post Share on other sites
DSE 5 #3 November 19, 2007 Do you mean the 15mm? No, it doesn't have IS, but doesn't need it as it's so wide. Quote Share this post Link to post Share on other sites
pilotdave 0 #4 November 19, 2007 There is a canon 14... but it's really big and heavy and ~$2000... so yeah, I'm guessing 15. Dave Quote Share this post Link to post Share on other sites

dragon2 2 #6 November 19, 2007 You don't WANT any image stablisation when skydiving anyway. It has trouble keeping up and will make the image worse than without image stabilisation. Some people do jump their video cameras with stabilisation turned on but often you can see the difference - you can get vignetting and/or a shaky image ciel bleu, Saskia Quote Share this post Link to post Share on other sites
cj1150gs 0 #7 November 19, 2007 Quotesaw that the standard 18-55 has image stabilizer Hi, Just FYI, although there is indeed an EF-S 18-55 IS lens, Canon's standard kit lens is still the non stabilized version. At least this side of the Atlantic... Carlos Martins Portugal www.cj.smugmug.com Quote Share this post Link to post Share on other sites
DSE 5 #8 November 19, 2007 Yes, I'm familiar with the L series; it's made in the same factory as their broadcast lenses. However, I wouldn't have thought new skydivers would be putting a $2500.00 lens on their camera, and the 15mm is very common. Perhaps I should have spoken more clearly.

Laszloimage 0 #9 November 19, 2007 It's a very nice piece of glass. At this focal lenght you don't need IS at all. Matter the fact is you probably would have a same problem like the Sony HC-7's (they have a built in optical IS). As others said already IS works great on longer lenses on the ground to correct hand shake. Also this Canon 14mm is expensive and pretty heavy. You can only take advantage of it if you are an experinced photographer and camera flyer already. Sigma has a same lens for half the price though... -Laszlo- the attached pictures were taken with this Canon 14mm mounted on the Rebel XT. Quote Share this post Link to post Share on other sites
VictorSuvorov 0 #10 November 19, 2007 the big difference between Sigma 15 MM and 14 MM (besides the difference in the size and the weight) is that 14 MM is Aspherical and has much less linear distortion. it also has an HSM focus (faster) Quote Share this post Link to post Share on other sites
