Pentax 67, meter prism help!
Hi thanks for your help, the battery is brand new and the contacts are clean, I gave it to the photography technician in University who could not work out what was wrong...maybe a loose connection...I contacted pentax for advice but they haven't got back to me yet. I bought mine before x-mas, I'm t...

Pentax 67, meter prism help!
Try taking the lens off and then putting the lens back on. I thought I had been sold a duffer from Mifsuds. It worked fine when the bloke showed me in the shop but when I got home I couldn't get the meter to work... until I took the lens off and put it back on - works fine until you remove the prism...

Pentax 645D - PMA announcement
Now all we need is for the back to be compatable with all old 645s (As all old lenses are) and pentax would have a potentially VERY big market. I know I would seriously think about it and save my pension pennies to have one. CHEERS Vic.

Correction lense +1 for 6x7
I recently "rediscovered" my old Pentax 6x7 but as my sight has deteriorated over the years (old age...) I found that I can no longer focus correctly and I am in need of a +1 dioptre correction lens. I have contacted Pentax uk directly as well as other Pentax repair shops but unfortunately they can...

645D aimed for Spring 2010
Who owns both a 645 and 35mm pentax? I wonder if anybody can look at thier lensmounts and tell me if it would look possible to built a 645 to 35 mm lens adaptor and have it retain infinity focus? ie... will the 35 mm lens fit inside the 645 mount on the body with enough room for an adapter to link ...

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
The Pentax K mount has a registration distance of 45.46mm. To retain infinity focus you need to use a lens with the same or greater distance. The Pentax 645 system has a registration distance of 70.87mm, so even if the lenses could be mounted inside the 645D's throat (which I doubt as lenses tend to...

645D aimed for Spring 2010
silly question really but have not got a clue Do you think the 5k price will include the digital back. Will a MF camera work with out a Digital back if so what is the advantage of a digital back. James

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...

manual focus with 645 lenses
Hello I have in mind to buy some more used 645 lenses for my old 645 body to bring it back to life. There are A and FA lenses on the used market. I only know the A lenses. Would you recommend to buy the newer FA lenses (better quality, maybe sharper?) or is it still better to use the older A lens...

manual focus with 645 lenses
I think you will find that the focussing rings on the the FA lenses are much lighter and smaller, therefore not as nice, as the F ones. Is there any evidence to suggest they are optically superior?

No better, the designs are the same optically.

645 Film insert question?
220 is just a longer roll of 120 (so you can squeeze more shots on). It's important to have the right back for the reel as they'll have take-up spools of differing widths and different gearings to accomodate a particular length - put the wrong one in and you'll end up with either overlapping frames ...

645 Film insert question?
Sorry to correct anyone, but it's not different spool widths that cause the problem. 120 and 220 film are on the same spool. The difference is that 120 film has backing paper the full length. 220 film only has backing paper at the start and end, this making room for more film length. The upsh...
