Tony Lau: I wonder how it will compare to Nikon 20mm f1.8g @f1.8 or slower, since the nikon only slightlyless in stop and much less in size and weight. unless some one specifically need f1.4, I find f1.8 is much easier to use and suffcient, if the quality is right.
according to dxo, T-stop of Nikon lenses is quite darker than F-stop.
It seems that Canon has the most _clever_ lens design approach.Its sharpness is flat over the whole image at the wide angle and more centered at the tele end. Which is good for both landscapes and portraits.Tamron is the opposite. Which is stupid for landscapes as well as portraits.Nikon is "flat" at wide and tele, but with a tradeoff of center/average sharpness.
tongki: and still have to change the batteries ???no wire connections for battery charging ???
Are you a historian or what?1) molded in contacts mean molded-in mini-usb port or special pins. Special pins mean adapter. Mini-usb port means: - have fun drying those tiny holes after emerging in the water.This would be prohibited by any tech. standard in all countries in the world. Because user can connect wet contacts to the car or 110/220V net.- have fun cleaning those contacts and holes after emerging into saulty water2) those pins must be done inside of the frame, so that you don't hook everything. That means even more troubles with drying + much more complicated body + much less robust body + 1cm of space3) the usb port is on the side of the GoPro. So electric connection would need a bendable cable inside. Tat means at least another 1,5cm of space inside.
All in all, this body would be so big and cost so much, that the demand would be vanishingly small.
Otherwise drill a hole in front of mini-usb port and plug a power supply.There are enough car usb chargers on the market and long usb to mini-usb cables.There are also enough of "opened" GoPro holders with access to all buttons and ports. For single body as well as for a body with a LCD back screen.http://www.amazon.com/Konsait-Protective-Standard-Border-Housing/dp/B00UA5DLGA/ref=sr_1_1?ie=UTF8&qid=1437643568&sr=8-1&keywords=gopro+holder
Zeisschen: I really can't wait for all the videos of people driving to Walmart
I would say not narcissic, but simply dangerous. People start doing stupid things when their GoPro is ON.
If you want to have a sealed body - no. Otherwise drill a hole in front of mini-usb port and plug a power supply.There are enough car usb chargers on the market and long usb to mini-usb cables.
ZAnton: Wow, well done Nikon!Significantly better than normal 810 and Canon 5 DS R
Yes, I meant noise performance. Nowadays noise performance is barely visible and pixel peepers start splitting hairs. 810A has a clear advantage over 810 and other cameras (wich comparable resolution)

ZAnton: And next zoom from Sigma will be like 24-25mm f/1.4; 1 kg weight; 17cm long and 12cm in diameter?Fro those who doesn't want to llose a moment:get 2 DSLRs with 2 light primes.
Pros will get 2 bodies.Amatures will be fine with standard f/3.5-5.6 zoom.Amatures will be happy with standard f/2.8 zoom.
So this lens is only for some techical freaks. Not a very big market niche.
fmian: I would rather just get a Canon 28mm f/2.8 IS.Take a step back for wider coverage and a step forward (or crop) for a tighter shot.IS mostly overcomes the 1 stop advantage of a f/2.0 lens, as you can easily shoot handheld at 1/8s with the IS lens.It's less than half the size and weighs 3.5x less than the 24-35.In terms of sharpness I can only look at the Sigma 18-35 f1.8 crop to compare it with, and the 28mm trounces that lens when it's also set to 28mm f/2.8.I'm thinking Sigma has kind of lost the plot here and are going for the spectacle of having a wider aperture zoom than anything else. With a lot of sacrifices though...Anyway, just my thoughts.
IS doesn't always help. You can't shoot people (irl, not in a studio) at expos. shorter than 1/30s, and you'd better have 1/60 s.So those 4 claimed stops of IS won't help. You cant photograph people at 1/2 s. To say nothing about kids.

cgarrard: Officially- This camera is severely handicapped without a built in finder- both financially and comparatively. A nice built in EVF for the same price would make this camera much more interesting to me.
I don't need a VF, neither my wife or mum do.I like VF in SLRs, especially those gorgeous VF in Nikon D800 or D4, but those tiny build-in nano-VF in compacts are totally useless.
They would better do an on-chip PDAF, instead of those stupid FPSes.RX 100 needs a longer lens. 70mm is way too short.
To DPReview: Thanks for the exellent comparison. It would also be nice to see lens comparison at 35, 50 and 85/100 mm equivalents. For example on the studio test scene at 60mm Pana has definitely sharper image in the center and 2/3 outside (cards). So those focus lengths are much more usefull than telezoom extremes such as 200 or 400mm.
0:40-0:47 AF hunts =)
ZAnton: Ho ho ho, concerning other Oly lenses, I wonder what horryfying barrel distortions will that 7-14 have.
the trick is, after correction (and cropping) it is not 7mm any more.It will be 8 or even 9 mm.
The Nikon 1 system has an f/1.8 18mm lens and an f/2.8 10mm lens.
The system doesn't have fast zooms.
For 2.7 crop f/2.8 can barely be counted as "bright".Ok, I missed 18 f/1,8.But still, their zooms are way too dark, f/3,5 and worse.No f/2.8, f/2.0 or better standard zoom.No wide-angle fixes, no wide-angle zoom,no more or less bright tele and portrait.And 32mm for 711 Euro - seriously? 711 Euro for a toy camera?To the top of all, 1 doesn't accept Nikon flashes and "old" Nikkor lenses are so unsharp, that they are totally unusable on Nikon 1. So for me, as a Nikon owner Nikon 1 doesn't make any sense. I bought M43 for my wife.
*conserning -> considering
All their recent lenses have massive distortions. Both Oly and Pana.
ImageAmateur: Looking forward to the Photozone review. I currently use an older Tokina 28-70 2.8 AF-D and it works lovely on my D300. Really nice optics.
If this lens comes with the usual Tokina optical excellence, and comes in around USD1,000 it will surely sell well.
Hopefully they keep QC in top form, avoid decentering issue with copies etc.
I don't care about VR, moreso optical and build quality. And at say, 1,000 it will not be much more expensive than some fast primes and much cheaper than others.
16-28 on a crop sensor?Are you OK?
Azzy: $1250 ??? 1,010g ???? 82mm filter???? no VR ????
Good luck Tokina....you'll need it
The price will go down very steep, but that's still not enough.
