67 lens on K10D
I just aquired a used K20D and have a Pentax K mount to 67 adapter, a 67 helicoid spacer and a nice old Takumar 67 135 F4 macro. It's all manual of course and any combination makes the package nose heavy. If you shoot macro, it's usually manual anyway. Actually two friends remarked on how light the ...

Digital MF overview/new Mamiya MF
http://www.luminous-landscape.com/reviews/cameras/phase-645.shtml Interesting overview of the current state of play with digital MF,...also first look at the new Mamiya digital MF which is more or less the old 645 with sensor added,.....presumably very similar to what we can expect from pentax so...

Pentax 645D - PMA announcement
At last a Pentax which has a dedicated White Balance button! What will the size of the sensor be? Will it be "full frame" or is the sensor smaller then the size of a 645 negative?

Pentax 645D - PMA announcement
This camera (and unlike the others it's ONLY a camera not a system) is entering a very serious market so it's going to have to offer something different to even be considered. Since it's of very conservative design, the only apparent way to be competitve is for th eprice to drrop considerably again...

645D aimed for Spring 2010
645 to 35 mm lens adaptor and have it retain infinity focus? Yes ie... will the 35 mm lens fit inside the 645 mount on the body with enough room for an adapter to link the aperture and lectrical contacts up? Don't think so and you would also have a problem with the image circle so it isn't poss...

645D aimed for Spring 2010
If Pentax stick to their traditional 645 comcept then there won't be a digital back as such. The sensor will be built into the body just like your DSLR sensor is. It might be a challenge to make SR as effective with such a big sensor to shift, but who knows until it's actually announced properly....

645D aimed for Spring 2010
I'm like Don, I canceled a few things myself. I will definitely buy me one. So far I've been using a Canon EOS 5D MarkII for digital, but I love my Pentax 645nII and the Pentax Glass. I use most of my Pentax lenses on my Canon as well. With what I have seen so far from the 645D on pictures, it loo...

Hartblei,..at last a use for pentax lenses
Well no, The pentax 645 is just an upgrade of the previous roll film camera and has a fixed sensor of only 30 meg pixels,..as I understand it(?) This camera is adaptable for all digital backs including the current 69meg modles and also for all main lens choices. Aslo offers use of movements and...

Could be that they have found a way to m...

I haven't read all of it so can't comment on it fully but it indeed seems good so far. One question for the K7 user can you do this? Its sophisticated autofocus system has 11 sensor points (with nine cross-type sensors positioned in the middle) to assure extra-accurate focusing on the subject. T...

Sorry Gary too late to go into everything. Pentax is of course promoting their camera on their own site so you won't find anything negative about it and they try to highlight everything that's good about it or try to make it look good, every company does that right? :) Pentax seems to be clear...

In lesser words, the sales pitch leaves one bewildered. I see that possible jumpers from 135 to the 645D may be some Canon users, specifically 5D owners as that model has quietly become the 135 landscape standard over the years. As far as other top 135 models, I doubt it as the cameras are worlds...

As far as other top 135 models, I doubt it as the cameras are worlds apart and have totally different capabilities as well as a far greater range of glass available. The 645 format is quite different, the photos taken with them have a different feel to the depth in the photo. That simply comes with ...

I've seen 6x7 shots with fairly wide lenses at f2.8 where the dof looks suprisingly narrow, giving the effect of looking at a miniature scene greatly magnified. I'm sure this is because of the larger size of the film compared to 35mm so I would expect similar results going from apsc to a MF sensor. ...

645D.......Still Waiting......
Gonna pass on that one, wish it did video... That's an interesting idea. 40MP video! You'll need one hell of a TV :D Is there some reason video on this would be better than video on a K7? look up RED cameras... bigger glass, bigger sensor, (you know what that means right?) obviously you'd be cro...

Digital or Medium format? I can see the 645D could arguably fit into either. Pentax challenges the boundaries! :) Well the 645D is digital so it can not fit under the film section right, or are you saying we can now discuss digital matter in the film section of the forum? Gonna pass on that one, ...

I think the big CCD sensor will overheat within 20 minutes or so :? And I personally don't want a CMOS sensor :( Beats the Nikon D90, which apparently gets very upset if you try to take a video lasting more than five minutes. :P
