Mr. Kitazawa slated to announce Pentax upcoming bodies in Dec 19'th

You don't get my point at all. If only the defocus estimation (either as an absolute difference, or also as direction) is changed, you can't call it "software AF".

About this research, although I find this really interesting (read the whole thing some weeks ago), it would mean a totally new line of lenses...
This method works by relying on the optical "weaknesses" of a lens to estimate the amount of defocus (and thus by how much we have to refocus the lens to get proper focus).
But I think this means the camera has to know a *lot* of things about the optic... A 50/1.4 won't produce the same "defocus" than the 18-55... And I can't imagine manufacturers offering backward compatibility on something this huge for them! I mean, this is the only major upgrade carrot they will have in the coming years, and the last thing they will want is to allow us to keep our current lenses...

True, but I don't care

The MF is enough for me even with the best EVF of today. It would be even better in future without a doubt.
But I think they will add a possibility to add lens profiles in their advanced amateur/pro models just like they are doing AF adjustments today. Moreover, the profile can be computed straight by the camera with some target. At least profile for not so long primes (again, that's enough for me).

Beer tomorrow fikkser?

Everybody thought it was IMPOSSIBLE. Two pentaxians ACTUALLY met today, and guess who approves this? (http://images4.wikia.nocookie.net/__cb20090911142315/uncyclopedia/images/1/1...pproves-1-.JPG)! Best rumor of the year?

Thank you for the beer and good night. Sleep tight, hälsa mamma!

Just curious, is this topic another 29 pages of nothing related to the topic? Saw no new body announced.

Kunzite · 12-28-2011, 01:08 AM

What new body? Please read the proper translation (v5planet's) - nothing was promised, and Pentax is not working on mirrorless FF&645D.
Dec 19th was the publication date of the interview, by the way.

Refer to the thread title. The "rumour" was of Pentax announcements, not general speculation inherent to the industry and imaging.

Kunzite · 12-28-2011, 06:40 AM

I did. The "rumour" was based on a loose translation of Mr. Kitazawa's interview.

The poll is on. If you've participated in this debate, you really should go vote: https://www.pentaxforums.com/forums/pentax-dslr-discussion/170327-poll-what-d...focus-etc.html
