If you make a camera with shorter registration distance you get:
- smaller WA
- bigger teles (you'll never find a DA70 or FA77 natively on a short registration distance APSC/FF).
In any case if the camera is smaller it is more limited in terms of ergonomics and handling. In term of features too. Sony latest A7 camera with SR are as heavy as K30/K50/K-S2...
Then if you change the registration distance AND work with contrast AF, you need different lens design. Sigma explained it. You need much smaller/ligher focus group so it can move back and forth very fast, something that contrast AF require. Meaning that you "legacy" K-mount lenses are never going to work that great on the new mirrorless. This is going to be slow.
This would mean that really only the new natives lens will work really well and that you need 5-10 years to get a complete ecosystem. That's another issue.
Now there the competition. What do you expect your product will bring that other will not and that will drive sales?
- K-mount support remove the size argument and add other issues with existing K-mount lenses.
- Supporting any lenses through manual focus. Not a differentiator, any camera ever made does that as long as the lens cover the image circle and that it comes with longer registration distance... Going short registration distance sure help but that's temporary. If everybody go short registration distance, you get back to initial state pretty quickly.
- An EVF? That's standard feature.
That's not that easy !
To me a K-02 with EVF, phase detect AF and proper design would allow for 400g K-mount camera that would do very well with a collapsible kit zoom, the DA20-40 or the DA/FA ltds. It is far easier to design a small/light standard K-mount body than to create a new mount.
Since you didn't quote anyone, I'm not quite sure with whom you are disagreeing. But you can say that you are disagreeing with me.
To me, the term K-02 implies an MILC; is that what you are referring to in the last paragraph?
I believe it is quite
possible that we are approaching another tipping point:
(1) when I got my first 35mm camera in 1969, almost every store in the US sold Koda
chrome film, which was the only reliably-available color film; some time in the next few years, Koda
color became the ubiquitous color film. I don't know exactly when it occurred, but it occurred over a fairly short period of time. People like me continued to use Kodachrome as long a Kodak manufactured it, but you had to support color negative in order to succeed.
(2) when I bought my Pentax Super Program in 1984, MF was the norm; when I bought my Canon EOS in 1995 (I didn't like the Pentax AF system) AF was the norm. I don't know exactly when we went from MF as norm to AF as norm, but my sense is that it happened over a fairly short period of time. I suppose you could still sell an MF camera in 1995, but not very many of them. Interestingly enough, I believe that Pentax's drop in market share came roughly during this time period, and I expect that Canon's in-lens AF system may have a lot to do with their becoming the most popular camera system.
(3) again, I'm not real certain about the years, but I believe that the switch from film to digital occurred over a fairly short period of time, maybe 2003-06. You can still sell film cameras, I guess (at least, I still see film for sale in stores), but I'm not sure you can succeed as a camera company if all you make is film cameras.
(4) MILC? This is still a question, but my belief is that we could be reaching a point where MILC dominates over DSLR. We will still see DSLR, especially at sports venues, but it is also quite possible that the proportions could switch in just a few years. This could be very good news for Sony, Olympus, and a few other companies, and very bad for the others. Thus, I feel that a small company like Pentax needs to take advantage of the agility that should come with small size and be ready to release an APS-C or FF MILC in a matter of months.
I have learned a lot in recent days by just asking questions. Until recently, I hadn't realized that focusing on a modern DSLR is partly a matter of faith - the body seems to send instructions to the lens, trusting that the lens will do it correctly; if I understand correctly, that "faith" part is what causes the front/back focusing issues that seem so strange to me (I had always expected that AF would work as I did/do MF - rotate back and forth until the image actually is in focus). My understanding is that the most recent MILC cameras use a hybrid focusing system - use the "traditional" DSLR method to get close, and then use a contrast system to get it right. Ultimately, that sort of system may end up being the preferred method, because it will eliminate all the tuning of lenses that seems to bog people down. In any case, Pentax needs to be prepared to roll out a system that supports hybrid focusing on an MILC body. In order to maintain their K-mount base, they may need to include a full-featured adapter with every camera, but your earlier paragraphs argue for a new shorter-registration distance mount. Your earlier words seem to say that a purely K-mount system will have trouble competing with the focusing speed / accuracy I'm expecting to become the norm in just a short period of time.
