Wouldn't argue with those choices. Both very nice products.

alexander kooistra: crop or no crop the aperture stays 1.2 is it not? I see people multiplying aperture by crop, but thats not the case. So it's a 32mm 1.2 lens with a price that suits a 1.2 lens...

but even Nikon play the game in their press release: "86mm equivalent in 35mm format", yet for some reason they don't state what its equivalent f stop would be.

I agree, it is priced appropriately given the aperture and construction. But Nikon are clearly selling this as a "f1.2" lens because people know "f1.2" lenses in 35mm format produce wonderful bokeh etc.

Good grief DPR. Adobe seems to have you doing basic market research for them now, for free no less. Too little, too late.

Looks great. It's very long(!) but that's to be expected - kudos to Sigma for putting this out. They're putting Canon & Nikon to shame with their latest line of lenses for non-FF users.

Andrew Booth: So is Canon going to leave us dangling with just a single pancake lens in the lineup (and 40mm isn't a great length for APS-C)?

I guess you're expected to slap one of Canon's traditional big-ass kit zooms on this thing.

Something like a 20 or 24mm f2.8 pancake might even persuade me to trade in my micro 4/3rds for an SL1.

Don't forget the voigtlander 20mm and 28mm pancakes. Canon could easily give crop users a 30mm f2.8 pancake but choose not to.

iShootWideOpen: This SL1 and the 22mm F/2 similar to the EOS M along with the 40 2.8 would make for an awesome small kit.

My bad. I completely forgot that 65mm f2.8 primes were popular as heck during the film SLR days. Everybody wanted one coz they were so useful.

@ iShootWideOpen
The 22mm F/2 won't work on the EF mount. Plus the EOS M is painfully slow in use. Plus 40/2.8 on a crop sensor isn't particularly useful. Yeah...great kit!

Good grief Canon.

You market the "the world’s smallest and lightest DSLR* camera" (note, I couldn't find what the * was referring to in the press notice)

But then you still don't offer a 20-22mm EF-S pancake lens to go with it? Most (all?) of the mirrorless system offer a pancake with a standard FL (35-40 equiv), but not you.

No, you try and flog your crop SLR customers a 40mm pancake designed for FF. (I don't recall 65mm SLR lenses being that popular back in the day!).

And don't get me started on the lack of a fast (f/1.4), modern, EF-S standard prime after all these years!

Still, this new camera will sell like hotcakes to the masses so what do you care. :)

Roland Karlsson: Can someone tell me whats so special with GoPro? What kind of properties does it possess that makes it possible to take photos that normal cameras cant take?

The only property I could see was the one that meant they couldn't actually get all the shots perfectly sync'd. I found the slight "judder" somewhat distracting.

Great news article

Is there that much demand for dolly footage taken 1ft off the ground?

Great images, but tip number 7:

Avoid taking any photos indoors or in low light

On Nikon D5200 added to our studio comparison database news story (186 comments in total)
In reply to:

bobbarber: Question. I've been wondering about this a while.

On the watch in the lower right-hand corner in the studio comparison image, are there supposed to be two white lines where the numeral 1 should be, or only one?

Both the OMD E-M5 and Panasonic GH2 show two lines there. The D5200 shows one line there.

Which is it?

If this is another camera-lens combo that fades out towards the edge of the image, then the 24 megapixels don't give much of an advantage, at least not without expensive glass. I'm assuming that the studio comparison was taken with good glass. I didn't check.

err Yes. They have two studio setups, which are absolutely identical except for those watches. Or perhaps...

it is the same physical studio scene and maybe a few of the elements have (been accidently) moved slightly after some of those older studio test shots were taken, e.g. look at the staples and some of the feathers in the shots from older and newer cameras.

My money is on the light hitting the (same) watch face at a slightly different angle to before.

Roman Korcek: So Sigma will offer a redesigned 30mm F/1.4 in addition to the new 35mm F/1.4? Is that not overkill?

@Suave Last time I looked the 30/1.4 was still smaller than the Sigma 35/1.4 and Canon 35/1.4 lenses

Agree with both these followup comments - the 30/1.4 makes much more sense for a crop dSLR. How long ago did Canon introduce the EF-S range? And we still don't have small & fast 30-35mm standard prime in the Canon EF-S range! Instead Canon would like crop camera users to fork out for the 35L. Well done Sigma!

In reply to:

ljfinger: Announced September 17th. I made my purchase decision a month later - and three months ago. You need to keep that sort of think in mind if you want your reviews to be relevant.

I have to agree with lj on this. Surely most folks who buy this type of camera will buy one on spec and price anyway (i.e. "50X zoom"). They'd have never heard of dpreview. And the rest of us know the general limitations of cameras like this, so a short review with a variety of samples is good enough.
The pocket fluff review was out in October.

Does the screen flip past 90 degrees? i.e. can the social media slave who uses this camera easily take a picture of themselves?

Gothmoth: i hope it kills the overpriced EF 35mm f2.

@ Cistron errr...I think Gothmoth was referring to the recently announced 35mm f2 IS, which is priced about the same as this new Sigma. Where have you been living this week??

In reply to:

Absolutic: Can you guys, or Andy in particular, list some of the lenses, that he intends to review first? You have done it before with a list of cameras in the pipeline for review, so I don't see why not give us a preview or at least a list of those you contemplate on reviewing, or those in progress. Yes, I know that it might cause people to yell, "review this one too please.." but still?

@ frozenshutter You mean "amateur lenses" like Canon's $2300 24-70mm II for example? :)
