PeterZOOM: Nice to see some new Canon stuff, interesting, a camera for astrophotography with hotshoe and build-in flash ... okay then.

You never seen a portrait of someone with the milky way behind them? Use the flash for fill light and then longer exposure for the sky.

mahonj: Why don't camera companies make the occasional monochrome camera - no bayer filter, no quarter wave plate, just very sensitive, very sharp images.

It would be very specialist and would sell in small-medium numbers, but if you can build an astro version, you should be able to build a mono version.

Apart from the different software/firmware, can anyone think of a reason ?

Canon sell so many 60Ds and 600Ds, they should be able to run a few mono versions.

@rare wolf
That's what coloured filters are for :P remember those?

You want to know the real reason? because the ISO performance would absolutely demolish their pro cameras so people would feel compelled to buy them. Then after they bought them they would start complaining that it was specialized.

Without a bayer filter you would collect 3 times as much light at every photosite(a bayer blocks 2/3 colors every pixel). This would triple the relative ISO settings, this would lead to complications like a high minimum ISO(near ISO 300 equiv).

And obviously raw files wouldn't really work with any available software since they assume a bayer arrangement. although a raw file is already just a 14bit black and white tiff file in a container so they could just give you that.

Fun fact, the Canon 20Da was the first canon DSLR with liveview.

On article Just Posted: Canon PowerShot G1 X review (519 comments in total)

the Dpreview guys just absolutely love the Canon G series styling and form factor. I mean just look at how well they rate the G12 which I would consider to be awful styling for a compact.

Regardless of anything, if Canon releases a camera that looks like a G series it will get a favourable review from dpreview. Simply read their other compact camera reviews, if a camera does anything different than a G series it's seen as a flaw.

There is so much about the G series cameras they perceive as perfect, you cannot add advanced usability to a camera in ANY way if it results in it not doing something a G series can do.

If canon released a full frame G-series with the same awful zoom design and hideous styling dpreview would give it a perfect 100, I don't think there is much question in that.

QQ in the UK. That's what you get for having weak currency! Blame your banks not Nikon.

You guys should just get it over with and adopt the US dollar, pound is basically worth as much.

Great to see a large inclusion of handheld night street photography, wish my 5dII could get away with that, although not quite $4000 wish :D

On photo BK6A9683 in dpreview review samples's photo gallery (5 comments in total)

picture really demonstrates the limits of the sensor, it's actually pretty good where it's well lit, but falls apart in the shadows. No banding is good to see, blotchyness is much easier to remove.

2 stops less and this would be a great image. looks marginally better than the 5dII at 12800 because of the lack of pattern noise(banding), it's softer than 12800 5dII though.

Wow that's some nasty noise and detail loss over ISO 3200, great nature cam but better options available for events/people.

On article Pentax K-01 Hands-on Preview (376 comments in total)

I understand why the mount side of the camera needs to be boxy, but couldn't they do something with the hand grip side of the camera? The grip just looks terrible, couldn't they make it thinner in the middle and then provide a more substantial hump?

It's like they wanted to make a mirrorless camera but couldn't afford to create a single new part, so they just sawed as much off the K-5 as they could.

Well it does take filters, that's one thing it does that other ultra wides don't already do.

Why did they have a 5 minute video presentation and not shoot any footage with the actual lens? obviously people would want to see how it preforms for video.

Honestly Zeiss makes some pretty weirdly spec/priced lens, but this one sort of makes sense. Nikon 14-24mm is great and Canon 14mm is great, but they both have extreme bulb front elements that make them prone to flare.

Can I arrange my photos in the Photos application yet? Seriously unbelievable that after 2 years I still can't choose how to arrange my photos so I can easily use it as a portfolio. The fact that I have to manipulate meta data to do it is unbelievable.

On article Just Posted: First Impressions - Using the Nikon D4 (84 comments in total)

Can someone explain the AF/M switch to me? I can't imagine why such a switch would ever be necessary. For people who use full time manual focus lens and want to use the half shutter press for autofocus? That's the only usage I can think of, otherwise the switch is on the lens.

IcyVeins: What is the point of having ACR and Lightroom when they edit photos in exactly the same way?

Some people don't want to buy photoshop and some people don't want to buy Lightroom. I already have production premium CS5 so I'm not about to drop another $100+ on lightroom.

bradleyg5: Honestly hate the IQ on iphones and other smart phones, never felt it was even close to most compact cameras. This on the other hand seems to be noticeably better than most compact cameras. Something like this could actually take some respect worthy pictures.

pureview phone, micro 4/3 compact, full frame dslr. Buying all those would make me a professional right? :P awesome to see such high quality cameras at every form factor now.

On a side critical note that lens does seem to have some pretty crazy distortion and field curvature and and with no ability to stop it down it's going to be pretty hard to keep flat objects in focus.

I'm going off this picture taken with it, the distortion is pretty severe and something is not quite right with the focal plane, might just be the way they are arranged though.

On article NHK working on 8k video sensor capable of 120fps (94 comments in total)
In reply to:

SaulTh: That is not 16x the resolution, it is only 4x the resolution i.e. resolution in each of its two dimensions -- it is 16x the *area*, or 16x the number of *pixels*. It is best to talk in resolution terms, that is the width or height of the sensor in pixels, since that determines the true ability to resolve detail, or crop/zoom while maintaining detail -- the total number of pixels is of lesser use as its relation to resolution is affected by the aspect ratio of the sensor, and resolution is proportional to the square root of pixel count -- silly to talk in total pixel count.

"4320 / 1080 = 4
7680 / 1920 = 4"

4x4 = 16

On article First impressions shooting with the Olympus OM-D E-M5 (269 comments in total)

Unless it has better high ISO performance than a D800 I wouldn't be interested. a 45mm f/1.8 is equivalent to a 90mm F/3.5 full format lens which is pretty unimpressive depth of field wise, if the ISO can't keep up what's the point?

Wow those shots are identical and what an absolutely disturbing issue to have. never realized how distracting it really is.

I'm doubting it is fixable in firmware, probably the electronics on the chip themselves that are causing it.

On article CIPA starts to report growing mirrorless sales (200 comments in total)
In reply to:

Maxfield_photo: I think the mirrorless trend will stabilize eventually. Until recently people had to choose between the image quality of a DSLR and the size of a P&S. Now there is another option, and so DSLR owners who were unhappy with the size of their camera are migrating to something smaller, and P&S owners who were unhappy with the IQ of their cameras are migrating to something sharper and cleaner. BUT, and this is important to understand, THE SKY IS NOT FALLING!

Some people actually like a traditional SLR design, there is just something fundamentally satisfying about putting a high quality piece of optical engineering up to your eye, pressing the shutter, and hearing the satisfying "chunk" of the mirror. I don't care how much vibration it introduces, it just FEELS like photography.

I'm afraid like Chicken Little, the camera industry has been hit on the head by the mirroless apple. Not everyone wants a mirrorless camera.

@ T3 You're totally right, I just got a panasonic micro 4/3 camera and was a little surprised and disappointed in how loud it was. Something about that mechanical shutter sound that just cues people in on their soul being stolen.

I very much wish electronic shutter were a feature in DSLRs and mirrorless cameras. I feel like they probably should already be able to do it, as long as the shutter speed is kept low. If micro four thirds cameras made no noise when they took pictures I honestly think lots of event photographers would move over to them. It's weird how I can take video of someone and they don't care(even though it's more revealing) yet the noise of that shutter makes them think I'm up to no good.
