Peiasdf: 23mm and 56mm are still using the same markup.
5-stop OIS, never heard that claim before.
Nikon 70-200 f/4 is claiming that.
qwertyasdf: I always wondered why ALL camera manufacturers are so conservative and complacent with kit lens apertures. it's been 3.5-5.6 for general purpose and 4-5.6 for telephoto since the beginning of time.Fuji is the only exception, taking half a step (stop) at a time, now that's progress!
@fatdeeman - those aren't kit lenses
Sdaniella: NEX: E-mount version60 f2.8 [FF FoV 120 f2.8]30 f1.4 [FF FoV 45 f1.4]
NEX: Sigma w/Canon EF-mountPlus Metabone Speedbooster EF-to-E (NEX) combined scenario:60 f2.8 x0.71 = 42.6 f2.0 x 1.5APSC = FF FoV 64 f2.0 !!!30 f1.4 x0.71 = 21.3 f1.0 x 1.5APSC = FF FoV 32 f1.0 !!!
Aperture Diameters*:*60/2.8=21.4mm max diameter*30/1.4=21.4mm max diameter
Why do you have the crop factor as 2x for the 60 and 1.5x for the 30?also, the crop factor affects the aperture also, not just the focal length. on MFT -> 60 f/2.8 = 120 f/5.6 on FFon E-mount -> 60 f/2.8 = 90 f/4.2 on FF
AbrasiveReducer: Just skimming but any system of measurement that shows a Sigma lens outperforming a Zeiss lens, even Cosina-Zeiss, seems pretty suspect.
check out the resolution tests of the new Sigma 35 - it's blowing away everything in its FL class
james skibsted: I guess being in Sydney, Australia won't cut it...
try the Sigma 200-500, I heard you can bounce it off space objects to defy line-of-sight limitations
The Travel Angel series is great - this should be no different. I have the A2691T which folds up really small and can fit in my backpack, but also gets up close to 6 feet in height and as low as 12-15". The monopod feature is really handy also...only a few twists to convert to that feature. Pretty stable too..best with a weight hanging from the center column
ptl-2010: Great for people who own the camera, but c'mon release the 7d mkII and the 70d already! I'm not about to buy a 3 year old camera when a new system should be just around the corner.
The 7D is still a very capable camera, probably the best crop sensor camera available from a total performance perspective. You can find many available used or refurbished for not much more than a new 60D, and with this upgrade you get some of the features back that make the newer Rebels desirable. Don't hold your breath on a mkII, chances are it wouldn't be all that different anyway.
Quick guide with great illustrated examples. Wish there were more like this!
Csabulator: I lost my faith in DPreview challenges. Just take a closer look on the 2nd picture. A fake picture almost won the challenge? Shame!!!!!!
wow you're right...i came in 3rd and when viewing on the iPhone both 1 and 2 looked great....upon closer look though it's quite obvious. Also a 1/500th ss could never create blur that long. i think #1 was deserving though.
0.5 star vote? really?
Nice shot, but doesn't really show the "Sport" of surfing without the surfer!
Duckie: Haunted by the past!
I got many OEM lenses before and almost all of them are now in the unused shelve. For this reason alone I will think twice and inspect samples when more people are actually using it. Using OEM is often a compromise and there are the associated risks. For RRP 1299 (even for a, say, 40% discount) I would not wear the risk. YMMV
you realize OEM means original equipment manufacturer right? i.e. Canon and Nikon. So this comment seems backwards.
Hi, not a portrait..
and a highly deserved challenge win. Congrats!
