Wonderful writing! Very useful not only for Fuji owners.

Great shots for evaluating this lens! Nice is the comparison shot of f/2.8 vs f/1.4. I wonder if you have the same shot in f/2? Just to see what is the difference in bokeh going from f/2 (Samyang) to f/1.4 (Mitakon).

I was wondering why Mitakon made this lens. After seeing the photos I am impressed and will remember this brand name.

Marty4650: The ability to use lenses you already own is great, but it doesn't earn any profits for Ricoh, beyond perhaps selling a few more camera bodies to people who own a vast collection of legacy lenses.

Ask Olympus if they made more money selling MMF3 adapters or 12-40mm PRO lenses? Ask Sony if they prefer their Alpha FE users buying FE glass or using E glass with vignetting? In every case the legacy glass feature is a selling point they hope you never actually take advantage of.

To launch this new camera profitably, Pentax needs a couple of new killer lenses that were designed specifically for full frame and designed specifically for digital. The legacy lenses for your old Pentax Super ME only met half that criteria, and as mentioned above will generate no new revenue for them.

If Pentax intended this camera to be a "great way to use glass you already own" then the big winners are the ebay dealers, and not Pentax.

@ Marty4650

40 year old lenses with coating will not cut it. But I have some lenses not that old, with A coupling, great coating and a great lens design. I forgot to mention some of my lenses are Tamron SP. They allow changing the lens mount. We mounted these lenses on a Canon 5D and compared with Canon L glass and quality was comparable.

luigibozi: Let's forget about legacy lenses. I know they were exceptional, but... who cares?!

People like me, who have a cabinet full of great legacy lenses do care. Why buy again what you already have? To me Pentax is already behind the curve in terms of camera technology: Not as great Video, No EVF option, Poor Wifi support. If I also need to toss my lenses, I would jump ship and go with another brand that has more modern camera technology. Legacy lens support is what keeps me holding on for a bit longer.

Vignes: FF DSLR, isn't it late. I'm a DSLR user but I have invested on Fuji MILC and playing with both. I'm sure the big C and N are definitely having some development on a mirrorless pro FF body and probably waiting for the right time to release after Sony makes all the hard work in marketing and selling the idea of mirrorless to pro's.

@ Alex Sarbu
Agree. I could not find one I was happy with. The one I bought I needed to heavily modify until it was descent. Have a look at my post above: "Concept Idea: EVF option". If I get enough replies here and if the new Pentax FF camera ships with a high resolution LCD display and if Pentax does not make a high quality LCD hood viewfinder I may consider to build one and make it available as an Indiegogo Project for others. Let me know what you think? Key quibble I have with any of the LCD hood viewfinders out there: a) Size, b) Mounting Speed, Fogging of Eye Piece (I live in a humid place), 4) No coating of eye piece = hard to clean. 5) Most have no diopter adjustment

@ SimenO1
You are correct. I was reminded in this discussion that for action photography the OVF is far superior. So a great camera would give the photographer an option. In terms of shooting experience Pentax has always been more traditional. So say the camera ships with OVF. And then there is the EVF option for those who need it, say for shooting Video, or for those who shoot very fast primes and need the more accurate focusing of Liveview.

@ watson076
I agree that current Mirrorless body sizes are out of proportion when used with big lenses. But what if you marry the best of both: Good grip and handling of a DSLR form factor and EVF. What if you even can have the choice of both. For action OVF is better, for Video EVF is better. And keep the DSLR hand grip and size for comfortable use of all the buttons.

HubertChen: Concept Idea: EVF option

Support for legacy lenses is a big thing for Pentax Users. I can see that with this might come in part a reluctance to use EVF. OVF is more traditional. Also in some shooting conditions it is superior to EVF. So why not have both?

Concept 1: EVF Module
Clip an EVF Module accessory to the top left of the camera. This converts the Gestalt to Rangefinder Haptic, which is a big plus. Much more comfortable to hold. The effective camera size will remain the same. Ideal for shooting video or to just get all the OVF benefits.

Concept 2: High Quality LCD Viewer
Place a metal frame around the LCD. Make the LCD viewfinder a magnetic snap on. Make it symmetric, so you can mount it either way. Use great optics with coating. Make sure the lens does not fog easily due to eye's humidity. And reduce the size. Third party products are 70 mm deep. They use only one lens element. Do it in 30 mm with fold back rubber eye piece. No need to be low cost. Be high quality!

@ SimenO1
I agree. A 4k display might be too expensive, but even a full HD would be amazing. Yeah, it Pentax would make a great LCD hood finder same quality as in the Pentax LX Viewfinder optional viewfinder it would be an amazing photographic experience. Give any other LCD Viewfinder a run for their money.

@ Roland Karlsson
Thanks for your reply. I was not aware of this solution. I looked up Sigmas LCD Viewfinder LVF-01. I would have two quibbles with it: 1) it is too big. I am using an LCD viewfinder of this size now. Bringing the viewfinder means I leave two primes at home.
2) Mount with Tripod screw. These are even two quibbles: a) The tripod mount is no longer really useful to shoot with Tripod, b) it takes too long to add and remove the LCD Viewfinder. I am using one with magnetic snap and it works much faster.

I very much agree that the resolution of the rear display need to be in the same range as a modern EVF, somewhat 720p, give or take

That said, they could go the path of Sony: New mount with shorter flange distance. Maybe go completely electronic. This would pave the wave for smaller and more modern lenses. Ship the camera with PK lens adapter. Be fully compatible with old lenses. So you could have the best of both.

DanK7: I am in love with my K3. What a brilliant beast. Not sure the pros/cons of FF would convince me that I need to switch. In practical terms, what does the K3 lack? Is the larger sensor (the larger everything) going to make sense?

I've recently invested in the Fuji X-T1 and lots of very nice lenses. I really prefer the handling, the menu and button placement and ruggedness of the K3. The X-T1 is no where near as hardy. Lighter and smaller, yes. But I keep having to replace lost rubber bits and eye pieces after hiking and traveling. The X-T1 controls and menu are also more clumsy and annoying than I would have expected, even after V4.00 firmware.

My ideal camera would be a K3 mirrorless with Fuji glass. Never gonna happen.

Hi Dank,

Thanks to point out OVF is better for action. I agree. I keep forgetting that as I do not shoot action. I also agree that having both would be best. Have a look a my post "Concept Idea: EVF option". Maybe if enough people like it Pentax may take notice and delivers?

I agree. Once you shot with a great EVF you do not want to go back to OVF.

Do you have Pentax Full Frame lenses and do you speak from experience? Did you made resolution testing so you are certain all Legacy Full Frame Lenses with PK mount are not up to the task?

I have a cabinet full of full frame PK lenses. They have been carefully selected when bought. If I were to replace my lens collection with new glass, it would be a 10,000 USD investment. Nothing that I would do lightly.

I shot with these lenses on film in full frame on a Pentax LX. I used a high quality scanner and got 12 MP pictures with excellent sharpness, corner to corner. So I guess they will hold up at least to 16 MP full frame. This is all what I would need. I am not interested in more megapixel. I am interested in more shallow depth of field, less noise at low light, and better Video Quality. If the new body will give me that, I will buy it. If it would break lens compatibility, I would jump ship this instance and go Micro Four Thirds with Panasonic GX-8.

HubertChen: I have a Cabinet full of PK Lenses

I am buying now a Panasonic GX-8, because I need good quality video and EVF. No current Pentax Camera can deliver. I will be using my lenses on the Panasonic Camera until the new Pentax Camera comes out.

If the new Pentax has great Video and EVF, I will sell the Panasonic Camera and buy the Pentax Camera.

But if not, I will sell my Pentax Lenses and Cameras and buy Micro Four Third lenses. I love my Pentax System. Deeply. But no good Video Quality and no EVF is just a requirement for the work I do. Selling my Pentax System will be like burying a best friend.

If they have great quality of 4K Video, (not behind Sony or Panasonic) but no EVF, and they have a high resolution rear screen (720p) and as good Live Video as on the K30, I will consider to build a high quality viewfinder for the rear display and may buy the new Pentax Camera.

I am shooting the pitch video of an indiegogo campaign. I have shot with K30 and NEX5 and the NEX5 is hands down better in terms of video quality. I compared footage of GH4 of very similar subjects and again, the 4k footage of the GH4 is another marked step up. Each time there is a dramatic increase in quality. I wish Pentax Video would be en par with Sony or Panasonic. The reality is that it is not. I am sure it is good enough for casual use. But for production there are simply cameras out there that provide much better quality in video. Also when doing color correction the Pentax footage would fall apart much earlier than the Sony footage. I am a big fan of Pentax. Using the K30 is fun, using the Sony NEX5 just drives me nuts. Pentax gets so many things right, using their cameras and lenses is very fluid. But sadly, their Video quality is way behind the curve.

Zvonimir Tosic: In February 2015, even DPReview noted the market release will be the end of 2015. Now we are half-way through the FY in Japan, and Ricoh is extending the FF release into a next FY in Japan, spring 2016, buying them extra 5-6 months.

5-6 months delay is not an accident — it is design. It means Ricoh knew it that the end of 2015 market release was impossible, but they did the stunt anyway. Now no explanation for delay is given, apart from "perfecting the product", "making it even better" which is a nonsense meowing of marketing cats, always ready to land on their feet.

FF was planned for Japanese FY of 2016, and users were manipulated with lies.

They will ship whenever they are ready. If I need a camera right now. I will buy one that is available. For me that is a Panasonic GX8 with a Pentax Lens Adapter. If I can wait, I will wait and will expect the schedule will slip further.

16:9 Setting (for the wish list)

With recent increase in display quality I stopped printing. I view all my images on displays now. Black borders take away resolution. So I shoot for and crop to 16:9. It would be great to have framing help for 16:9. Some people may prefer a crop straight when shooting. Some may prefer guide lines showing 16:9.

Even if there is no EVF, some will shoot with live view and LCD viewfinder, so this setting still can be used in that way.

A) Shooting Video
B) A good EVF nowadays is closer to the final photo or video than OVF. E.g. you can see depth of field
C) More information, such as Zebras

At this time not really. 1080p recorded on a Pentax is of dramatically less quality than 1080p on a Sony. And 4K on a Pentax is simply not available. A Panasonic GH4 footage just blows it out of the water. When I started video, I liked the shooting experience with my Pentax Camera and I liked the rendering of my Pentax lenses. But the video quality is poor by comparison.
