SimenO1: I'm impressed that they got hold of a whole 300mm wafer and made the whole thing work without flaws. Also reading out that large area 26 times a second is impressive.

That said, I'm very dissapointed with the pixel size they choose. Maybe that is a result of a very old and coarse litography process. With a modern technique they should have aimed for gigapixels with 16 bit depth. And while they are at it, not crop the circular sensor to a rectangular shape. Most (all?) large format lenses makes circular image circles. Aspect ratio of the print should be a decition in the post process.

BTW, I hope someone make a 8x10 camera with a scanning sensor too. That could easily drive down the price by 99%.

That makes sense. With 75 micron pixels stitching are possible with a fraction of a pixel wide uncovered stitch line.

Good phone cameras are for gradmas, that dont have a real camera.

While there may be one or two on DPR, most of DPR readers have real cameras with real buttons, real ergonomy and useful feature sets.

Let grandmas be grandmas, and photographers be photographers.

SimenO1: Its quite a price for such a lens. I guess the price are a result of a lack of healthy competition. If there was real competition the price would likely be much lower.

A 200/3,2 on FF will give us the same FOV, same DOF, same shot noise at the same shutter speed and so on. Resolution may be the only point where it is better then FF, but that is yet to be proven (5DSR+EF200/2.8 vs GFX+250/4 vs K-1 PS+200/2.8)

@Dheorl Yes I'm assuming higher then base ISO. Dont see anything wrong with that as the ISO scale is long and base ISO is just one of the many values.
Yes there are other factors, none of where the Fuji 250 is proven best. Some of the values are also highly subjective. But all of your "arguments" are details.

The basic and most important numbers are FOV, DOF and shot noise.

Hubertus Bigend: Wonder how long Fuji will be able to keep up those price levels for an undoubtedly attractive camera system, after Nikon and Canon will have entered the full-frame mirrorless market. Right now, the lens and the converter might still be adequately priced for what currently goes for medium format. $ 329 for a simple hollow cylinder, on the other hand, is overdoing it even under such considerations.

@Astrotripper: I believe Canon/Nikon FF mirrorless will have an impact on the competition with GFX. The sensor sizes are not that different that potential customers wont consider both.

It makes no sense to have as small as 1,27-1,5x sise difference between formats, for each company. That would result in too many formats to develop lenses for. Fuji X to GFX have 1,9x difference, that makes more sense.

Veselin Gramatikov: Pff...to short Fuji. I hope for 300/4. 300/4 on aps-c is very good all round lens for sports and wildlife. Now this is short and expensive. Just look nikkor 300/4 PF lens. It`s expensive but cheaper than this.... almost twice as cheap. Seems i can not switch to ILC system for wildlife.

@wasTF The bigger the sensor, the bigger the optics have to be. Its not about complexity but price, size and weight og glass. The same goes for wide angle. Short focal flange distance is an advantage for wide angle regardless of sensor size.

YOU compared to ics cubes vs fridge, said OVF vs EVF was NOT about peoples personal preferences and argued that mirrorless could take pictures a dslr cant. And that technology is all about age, not how well it works.

And now you just say your comments was all about your own needs and thoughts? Not about market or tehcnology in general. As I said, its facinating to see how some people lack the ability to understand other peoples preferences.

As I said, both technologies are here to stay. And I'm not talking about my personal photo bag, but in the world.

@MagnarW:
- Some DSLRs can turn off mirror flipping to increase fps for those cases where fps are more important. Live view can be used simoultanously. A screen hood to if you want.
- How? You can do the same with DSLR with a screen hood.
- Less complex? How? A live camera and tv combination are less complex then a mirror and a prism?
- Wrong. All current EVF have less DR then the sensors they are used with. Correct exposure are so much more then matching 10% grey with 10% grey. Thats only a single point on an infinitly long scale.
- You can find small or big mirrorless. Small or big DSLRs. Some DSLRs are smaller then other mirrorless. Those scales are overlapping, and there are no clear fasit on what is best. Ergonomic size and shape are more important then small for some. Same with weight vs balance.

As I said, both technologies are here to stay. Some prefer this - some prefer that. Is facinating to see how some people lack the ability to understand other peoples preferences.

The wheel is even older, yet its still used more every year around the world. According to your beliefes wheels should be conquered out of the market long ago. The logic fallicity is that the age of the technology is irrelevant.

Yes, EVF are better then OVF in many respects, but OVF are also better then EVF in many respects. We still stand at the green vs orange -logic. Both technologies are here to stay.

No - this is more like one year green paint outsells orange paint, and next year its opposite. Some prefer this, some prefer that, but not at a constant rate. If orange outsells green green four years in a row, some fool may project that orange will eventually kill green "its simple math" (but a logic fallicity)

I can only guess Canon, Nikon and Pentax bosses are laughing when 2/3 of the manufacturers flee 2/3 of the market because of such runaway projections. They may choose to stand in both camps, but one DSLR company wont give away that huge market share to the other two DSLR companys just like that.

JensR: Thank you for giving Pentax a feature interview.

Nothing earth-shattering, although it is great to hear a firm yes to the K3iii and the GRiii (I'm only interested in the former). IMO Pentax already has all ingredients for the upgraded K3 distributed across their other recent SLR cameras.

I use a modified K-01 for IR photography and despite its quirks, I would really like to see a K-mount upgrade to that with modern day on-sensor PDAF. But it seems that is very very low on the list of priorities.

Very interessting! Thank you :)

Retzius: How limited is the Ricoh R&D team? This guy gives me the impression it consists of 3 guys in a rented studio space.

What is the relevance - really? Please grow up. Regardless of count - they have made some truly amazing cameras and lenses.

@Holger: Sony A-series had a mirror with 2/3 constant transparency (to the sensor) and 1/3 constant reflectivity (to the viewfinder). There was no switching. I have never heard of any mirror technology that allows switching the reflectivity or transparency.

Let me build more on your idea. If there was a dual sided mirror with 0% transparency at a 45 degree angle, we could place the sensor where the matte plate normally are, and an EVF screen laying on the floor of the mirror house. It would truly be amazing to have the impression of looking right through the lens, in the optical axis, but still have EVF and all the info that may put onto the image. I doubt it would make the camera slimmer because of VF optics, but it would be a unique concept and feeling.

Androole: I understand the limited R&D budget, but I feel like it really paints them into a problematic corner.

Particularly in the case of medium format. I guess there will continue to be traditional users who want to use MF cameras as purely tripod mounted beasts at all times, whether it's in a studio or out shooting landscapes. But while mirrorless only provides modest size advantages at the APS-C and 4/3 scale, it leads to massive size reductions at the FF and MF scales because the mirror box just needs to keep getting cubically bigger with increases in sensor size.

For two cameras that have roughly comparable capabilities, this is a pretty tough pill to swallow:

http://camerasize.com/compare/#211,678

And it's not like Hasselblad has a lot of resources to throw at R&D, either. They are a very small shop.

Some companies thrive on traditionalism, but somehow I worry that the Pentax name is not strong enough to carry on in that respect alone...

Pentax _are_ a strong name in the MF market.

First, MF is not targetet at mountain hikers or for street snapshots and purses. Compact size are not a first priority, professional use are. Size-sensitive customers should consider Hasselblad and Fuji in stedad. But even those will put on lenses and see the size difference diminish.

Add EVF to that wish and I'm with you. :)

Looks quite balanced - almost like pickups vs sedans. Those that believe sedans will win the whole market in the long run, or vise versa, need to reduce their ignorance.

PhotoKhan: The US is becoming scarier by the day.

The standard NRA solution to eccessive gun crimes are more guns and less regulation on hwo that can own and use guns. I lost my faith in that country long ago and its going worse day by day.
