First I want to say that the new exterior of the Sigma 30mm is beautiful. If you just look at the web images, it looks like silver plastic. But both of the silver parts are metal. I know this lens is highly praised for it's sharpness. But I've compared it to my copy of the 16-50 and it just doesn't impress me. Sigma 30mm f5.0 vs Sony 16-50mm (@30mm) f8.0 Center: Sony might be slightly sharper, very close. Left center: Sony sharper Right center: Sigma sharper Corners: Sigma sharper in 3/4...
Can anyone confirm that the Nikon 55-300mm VR has a max aperture of f5 at 200mm? This is claimed on Ken Rockwell's site, but I want to make sure as otherwise I would prefer to get the 55-200mm. --Dpreview Auto image-resizer for Firefox :http://userscripts.org/scripts/show/105066Chrome version here:http://userscripts.org/scripts/show/105067
The fastest shutter speed is supposed to be 1/4000. When in manual exposure, it seems that this value can only be reached at F11 or higher. Same in TV mode. (At least on my G1X.) Any way to get the highest shutter speed at, say, F5.6? . . . my camera stops at 1/2500 at this aperture, and the rest of the speeds are grayed out. Thanks.
I'm in the mood for some magnification for my 7D and I've been debating both of these lenses. I know a zoom is more versitle but I keep reading this prime offers better IQ. Will the 400 prime generate better IQ than the 100-400? I have the 70-200 2.8L USM II and I love it's IQ and overall picture quality and plan on getting the x1.4 III version converter for it which will put this combo at a max zoom of 280mm f5.6. I hear the prime 400 will not autofocus with this same x1.4 III converter and...
I know this is something I should be able to solve by experimenting, but given the potential for error, it seemed worth finding whether someone knows the right answer. When using manual focus lenses which have a depth of field scale, using a Nex and Speedbooster, if I set the lens aperture at, say, f8, then the effective aperture is f5.6. If I want to use the depth of field markings on the lens, should I use the ones for f8 or f5.6. I understand that the depth of field is reduced, compared...
Hi, I was really surprise when i spotted a hot pixel when taking a family pic at iso 1600 (around 1/60, f5.6). Then I made a quick test, with the lens cap on, here what i got from an iso 1600 @ 30 second: To make it easier to see it from the web, i +2 the exposure: exposure +2 There are hundreds of hot pixels... Is this normal? I have search thru the internet, I found some people says it is normal. But, is that really true? Or this only applies for early production of d800(e)? Thanks

Okay, so I've been having this weird problem a few times lately... Changing the aperture is having no effect on exposure. So for example, today. I'm using a external strobe and Manual mode. Shutter is on 200 and ISO is also lowest it can be at 200. I'm out in the sun so thing are pretty bright. Overexposed, in fact. Since I'm already at the lowest ISO, and highest sync speed for the shutter, the only thing I can do is close up the aperture... but this does nothing. I close it up, take...
