Suntan: So these spectabular lenses need vignette correction? That's kind of a letdown.
The quality cost is *not* from the correction, but from the aberration in the first place.
Do you have an aperture series on the test chart versus its compact competitors?
Can't they have evenly spaced stops on the aperture ring?
Mike in Taiwan: I know I flunked my science classes and am mathematically inept...but since when does comparing the Sony with a native lens to Canon and Nikon cameras with third party lenses constitute a legitimate comparison? It seems this should have been thought out more...and will only raise fanboy furor... It's also a missed opportunity because the test could have compared each camera with it native 35mm lens and then demonstrate the Sony's AF capability using the same Canon and Nikon lenses...Wouldn't we have all been better served in that scenario?
I don't have a problem with the Sigma being 3rd party, but my issue is that you used a 50mm on the DSLRs and a 35 on the Sony. Wider lenses need less focus movement when you halve the subject distance like that.
Clearly Nikon indexes from the back edge of the hot shoe rails, not the front.
chillgreg: Does the pixel shift technology mean that this camera can emulate a Foveon sensor's output?
It's better than Foveon because it has higher resolution to start, and better color separation.
Of course, it's limited to truly static subjects.
Mal69: At 100% file quality you would be very hard pushed, even on extremely large displays, to notice any JPG artifacts, indeed i would challenge you to find any at that level of compression.
I do blu ray screencap comparisons for my website and i choose 100% JPG compression over lossless PNG files because i have tested PNG against 100% file quality JPG and even at 100+ inch screen size i could find no visible artifacts in the JPG file.
The benefit is that you can use 1/4 the data, not the quality increase at a given size.
For users with new high-resolution screens, this could serve an UHD background image in less data than a 1080p JPEG.
Now why couldn't the first generation have a real grip like this one?
Eddie_Wong_F-14: I feel like I'd prefer the classic pull-push design, by my experience with T150-600.
When I rented the 70-300L, I could push pull zoom using the hood. I'm sure you could do the same if you loosen the zoom friction on this
mike earussi: Never heard of a CPL that can transmit 90% of the light. Wonder how they're pulling that miracle off?
Probably 90% of the theoretical maximum (so actually 45%) compared to other ones.
I have an old linear polarizer that lets through only 25% of the light or so, far from ideal.
Franz Weber: I like the idea of the Stylus 1 concept, but IMHO it has three week spots that can and should be impoved:- wideangle should be extended to 24mm or at least 25mm- IS is rather poor in comparisson to the competition- CA are visible in JPGs due to the use of the outdated Trupic 6 chip
I find the stabilization to be excellent.
Sangster: Only US$4490!
It would focus really slowly. Really slowly.
gravee: Can someone explain whats so special about Arca swiss plates? I'm a relative newbie to photography, I have manfrotto plates on all my cameras and tripods but everytime I try to look for a body strap like this they are only compatible with Arca Swiss plates.
They are compatible with everything else, and they can slide back and forth in case you need to balance or center your gear (such as forward and back with telephoto lenses).
Preamp: Bend the sensor... I guess grinding down a thicker slab of silicon just like a lens would be a little more accurate and avoid errors like "sensor curvature linearity". They'd surely have to make some thicker wafers first (which should be pretty expensive) and then adapt their lithography for curved surfaces (which might be even more expensive).
Bending yielded sensitivity gains in the center.
Furthermore, it is hard to etch the circuits on a curved sensor en mass.
breth: It's about time one of the camera manufacturers puts out an environmentally sealed serious pocket-able compact with large sensor. For backpackers, rainy day streetshooters, and people working in tough conditions that want great IQ.The more smartphones get better as cameras, and the more people tire of lugging their dslrs, this market should start to develop.
I did mean a waterproof GR.
I have a GR but would love to not need to baby it.
Just another Canon shooter: 1. " it appears they are fabricated flat, bent into shape using a custom machine, and then backed with ceramic to maintain the bent shape permanently. " You can make it cylindrical this way but not "spherical" (curved in both directions). But if it is cylindrical, you need a lens corrected for field curvature in one direction but not in another.
2. "with a 1.4x increase in sensitivity in the center of the sensor as well. The latter may be due...": I like the "may be". Curvature alone will not change anything in the center.
3. " In fact, a 2x increase in photon collection efficiency is reported for the periphery..." Compared to what? To a flat sensor with the same lens, maybe. But to a regular retrofocal wide lens on dSLR, not likely.
4. If the sensor is "spherical", correcting distortions can be a challenge.
Curvature changes the electrical properties of the semiconductors, since band gaps are affected by strain and the like. They reported that the sensor evidently benefited from the strain even in the center.
Ahem GR-W ahem.
I would buy it if they didn't ruin the ergonomics in the process.
marc petzold: For sure, Nikon missed the train here...after such a long time, Nikon comes sadly only with some very minor tweaks, and release this as 1.11 firmware?
Dear Nikon, please watch Ricoh, to show you an example. The firmware for the Ricoh GR is already at the next major step of 4.0 these days - and many enhancements inside.
If i'm into buying a APS-C 28mm prime lens digicam, i'd choose the Ricoh GR any sec over the Nikon Coolpix A, you even have a 35mm Cropmode onto the Ricoh, and the customization together with twin dials is a dream onto the GR Series, alongside dozens of other tweaks to the GR, Ricoh does like Fujifilm really listening to it's customers, and providing really useful - free firmware enhancements....besides that, no Nikon bashing here - i've used, loved my D40 to D7000, still using the D90 & D7000 way much.
The only bad thing - the Ricoh GR is about 100 EUR more expensive than the Coolpix A here into germany.
Listens to customers? Ricoh reads my mind!
Practically the week after I first encountered shadow noise in the corners, they came out with 3.00 which let you turn off vignetting correction.
Sergey Borachev: Nice! but how about a fix for the exposure problem. It under exposes so often without too much provocation.
I use center weighted metering and it never behaves unpredictably.
Try it; you can use the AF lock button to separate focus, metering, and composition.
I love this camera even more now.
