shooter mclens: I had the S5100. its best feature was the 10x zoom. it would have been an excellent camera had it offered more direct controls, but it was decent for that time. i cant recall if there were even any 6mp cameras back then, and the consumer DSLR was still years away. I remember taking that camera to Africa. Fuji has always made pretty good cameras.

I had the Canon S1 which was a direct competitor.

Is there a true tilt and shift for FE mount yet? Not that it matters. Mechanical lenses work fine through adapter.

AstroStan: At that angle of coverage, rectilinear does not mean "no distortions" unless you qualify that term, e.g. "as distortion free as is possible with a planar sensor". The geometric distortions due to projecting a spherical section onto a plane are intrinsically unavoidable (just ask a map maker).

Good explanation Alphoid.

I think put more simply, a perfect rectalinear lens in front of a focal plane at this wide a viewing angle has a great deal of perspetive distortion. Don't blame the lens. It's what you're asking for.

Why are you asking for it? Because "correct" is relative, ESPECIALLY when you pass 90 degrees.

Lets hope they're including a 4x digital zoom. That would give a total zoom of 64x and a widest focal length of 23.4mm

I think a EVF mirrorless x-trans version of that Sony 50mp MF (lite) sensor is possible. It certainly wouldn't conflict with their APS-C business any, which they have a lot of lens development already invested in. I don't know if they'd make a leaf shutter version to go after Hasselblad but if they could make a body for ~$4k and 30/45/65mm f2.8 pimes <$2k they would probably entice a lot of FF shooters to dabble. That's not far from A7 money.

Chris Yates: $6K. Is that all? I think I'll get two, one as main and one as backup.
In all seriousness, they're "beautiful looking" lenses, but too pricey for zooms and I prefer primes.
I love my old Mamiya 645 prime glass for a fraction of the price.

At least they aren't completely outclassed by a 24-70 or 70-200 f2.8 FF lens. Their f4-f5.6 aperture is at least reasonable for a high priced zoom. A lot of MF lenses lean on compatibility with their systems more than competitive optics but these lenses provide a pretty general purpose range with reasonable aperture.

It's 2x the resolution of the highest resolution FF sensor so 4x the cost of equivalent FF products seems reasonable to me. This is right in line with that. These lenses have to resolve a lot more detail after all.

AshMills: Equivalence police- that's 16-32mm f1.6-2.4 and 30-60mm 1.6-2.4 to you.

Uhhh, what? Crop is .64

40-80 f4.0-f5.6 = 26mm-51mm f2.6-3.6
75-150 f4.0-f5.6 = 48m-96mm f2.6-3.6

You seem to be using crop^2? That would be used for calculating the equivalent ISO to use. For example If you were shooting the Phase 1 at ISO 250, the FF equiv ISO would be 100. That would give you the same exposure as the above listed lenses with the same shutter/depth of field/diffraction/total light/etc.

nothing like 3mp images to show off a 50mp sensor :(

What's the crop and aspect ratio of this sensor? Somebody want to save me from calculating it based on the pixel size?

agaoo: It really looks good, I'm drooling but I don't think it's worth paying almost double the price of SONY A6300. Most features are similar to A6300 while Fuji's body looks more robust and design is sexy. Sony has better lens choices. I can't decide :-(

Sony does have Sigma's line to call on now as well don't forget which includes the 18-35 f1.8 50-100 f1.8, and 35 f1.4

Then agan nobody comes close to Fuji's 56mm f1.2 or 16mm f1.4 in APS-C.

ttran88: Suddenly 4K will be "relevant" in the XF forums.

How are you supposed to feed the EVF and rear screen without continually reading from the sensor? How about on sensor autofocus and metering? Reading data from the sensor quickly is not a video feature but it DOES give you all the data you need to write out some video while you're at it. Video is not driving up the cost of this product it's a side benefit.

And 4K being relevant to a T2 buyer because it has 4K should be pretty intuitive right? Or does the interests of a camera brand's users have no dependency in your mind to the capabilities they excel at? People who don't like the T2 probably won't buy Fuji which means they probably won't be talking on the Fuji forum. People who own old Fuji's constantly buy new cameras.

joystick can be used on-eye, touch screen you have to pull back to set focus. Joystick > touchscreen for an immersive camera experience.

In reply to:

Joe Ogiba: The T1 was the first camera with UHS-II SDXC slot and the T2 is the first with two UHS-II SDXC slots. UHS-II is 3x faster than UHS-I and is fast enough for 8K video.

MP matters on sensor ratio

On a 16:9 basis, 7680x4320 = 33.2 MP
On a 3:2 which crops down to 8K you're talking 7680x5120 = 39.3MP
On a 4:3 which crops down to 8K you're talking 7680x5760 = 44.2 MP

Add a few pixels on all sides for some digital sampling and you land on something pretty much like Sony's A7Rm2 for 3:2 rato: 7952 x 5304 = 42.2 MP

I think that's more like an 8K sensor in the future. UHS-II though should facilitate 60fps 4K and even a less compressed bitrate too.

Technology is one thing but cmon curmudgeons. There's no way you don't look at a camera with dials for shutter, ISO, aperture, exposure, and still have a dial under your finger to use for whatever else you can desire and not start to drool. I'm starting to feel like the camera is more about the enjoyment I get out of using it and all the dials and big EVF really make it fun to USE, not just fun to look at the pictures that come out afterwards.

I agree joystick > touchscreen. Sure both would be cool but of the few touch screens out there, even fewer have joysticks.

On article Special K? Pentax K-1 Review (2616 comments in total)

I love the pixel shift mode but it's still in need of some better procsesing when it comes to motion. Similarly to a metering sensor it aught to be able to track objects across a pixel level variation when it finds the shots are not the same and instead of blending away, it should be smarter about falling back to a single image.

I was also kind of sad to not see a resolution expanding mode from the pixel shift like Olympus offers. An 8-shot 144mp mode would be pretty juicy. I feel like Olympus was dinged for not offering a dynamic range mode in it's implementation but Pentax is conversely not getting dinged for the lack of a super resolution mode. I wounder how many film era Pentax lenses can resolve anything like 144mp?

I would be more concerned about lens selection with this than AF. Making the A7II look like a more flexible alternative is a hard negative to overcome.

HB1969: I was a little disappointed with the pixel shift images. They look rather flat and lifeless, especially the greens, though I'm sure editing would bring them back up to punchy images.

Check out the space needle pixel shift shot without all the green.

I don't think it matters either. You were the one who brought up a "more noisy image". I was meerly explaining that the technology difference between the A68 and the T6 is so extreme that the -0.3EV light loss will NOT contribute more noise when comparing directly between them. I agree the A68 will have more noise than a D7200 mostly due to the SLT. I do not agree it will have more noise than a T6. I also agree, it's an irrelevant difference. The AF speed however is probably relevenat. The T6's AF system, sensor, and it's kit lens are all archaic (exact same as T5). The more powerful processor in the T6 vs the T5 expands the ISO range but does little in terms of noise. This was true years ago when DIGIC4+ arrived. It offers a lot less than the DIGIC5 you'd get in a T4i or an SL1 let alone the DIGIC6 you'd get in the similarly named T6i.

naththo, you really think the 18mp canon sensor from nearly a decade ago which isn't even quite APS-C sized is going to have better high ISO performance than a modern Sony 24mp APS-C sensor with a -0.3 EV light loss in front of it? Really?
