Haven't used an enlarger or a bronny in years...... was also secretary of the Uni camera club in between working in Jessops.....

Did 12x16 cibacrome printing - tricky job getting the temp & colours right.

Got a nice twin lens reflex 6x6 knocking about somewhere - doubt even current Jessop staff would be able to tell the defference between 120 & 220 film should I ever try to get it out of the cupboard.

My old boss was a fan of hassleblads.... I managed to nearly knacker one of his once by attaching the lens b4 re-cocking the shutter.....
 
Oooooh Zenza Bronica :P used to lust after them as a teenager.

Looking at some of the internet blurb it seems most of the Pentax DSLRs are compatible with every Pentax lens made :D albeit with loss of some of the camera features.

father's day coming up...........

so - digi SLRs...........believe i can get a digital body and use my old Pentax K fitting lenses from the early 80s :roll: along with all my filters and associated gubbins :lol:

is this correct?
is it a good idea?
should i just ditch the 'orible heavy old lenses and go for modern lightweight instead?
Check this out Mr. Panda....

Perhaps the most backward-compatible camera brand, a new Pentax digital SLR camera will accept a lens made for one of the first Pentax K bayonet-mount 35mm cameras back in the mid-1970s. If the lens has auto aperture control (Pentax KA) and autofocus (Pentax KAF) capability, those features will couple to the D-SLRs controls. A Pentax digital SLR will even accept old Pentax screw-mount lenses made for cameras in the 1960s and early ‘70s, provided a Pentax Lens Mount Adapter B is used.
For Nikon compatibility, this is probably the most useful table you'll find on the net: http://www.nikonians.org/nikon/slr-lens.html

Lens focal length will be multiplied by roughly 1.35
That's about right for the mid-range Canons with the APS-H sensors, but cheaper DSLRs have APS-C sensors -- multiply by 1.5 for Nikon, Pentax and Sony and by 1.6 for Canon...

so my 24mm Pentax w/a lens would function more as a 32mm would if fitted to dslr? Pity that :cry: lerve that lens :oops:
Worse than that Mr. Panda; your 24mm would be more like a 36mm on a DSLR with an APS-C sensor... :(

This is where the smaller light-sensitive area of a digital SLR really scuttles wide-angle photographers who are used to travelling around with just a film body and a compact 28mm/35mm prime as their "standard" lens:
  • Put a 28mm from a film SLR onto a DSLR, and you get an apparent 42mm focal length, which is more like a short standard lens than a wideangle.
  • Put the kit 18-55mm zoom on your DSLR which is 2-3 times the length of a wide-angle prime and lose the compact feeling of the camera and the brightness of a prime lens.
  • Or pay an arm and a leg for a 20mm lens which will have a 35mm equivalence of about 30mm.

thanks JohnH - Useful stuff. :D

Looks like w/a might be a problem though. Bums.

In the Pentax table does that then suggest that a modern digi 18mm lens has the same angle of coverage as a 28mm would have on a 35mm film camera? :cry:

You're welcome! :)

[Edit: I've just stumbled upon a very useful lens compatibility table for Pentax cameras: http://www.mosphotos.com/PentaxLensCompatibility.html 8) ]

Yes. The conversion factor for Pentax, Nikon and Sony DSLRs with APS-C sensors is approximately 1.5 (or one-and-a-half) -- so to see what 18mm on a DSLR would be roughly equal to on a 35mm SLR, just add half as much again, like this:
18mm + 50% of 18mm = 18mm + 9mm = 27mm (-ish)

My favourite lens is a 19-35mm wideangle zoom. I love it. But if I was to mount it onto a budget DSLR, it would become equivalent to a 29-52mm zoom. Bye-bye super wide angle. To get the same effect, Sigma make a 10-20mm wideangle zoom and this lens has received some very good reviews, but it ain't cheap...
 
And of course if the lens mounts , then a modern lens can also work on an old body.Well it can do with a Pentax anyway.


However the super duper wide angle digi lenses will not quite work on older body without a small amount of darkening around the edges of the picture. Most of these lenses have a "D" in their title suggesting they are for teh smaller APS-c sensors.
 
I had a fantastic 2nd hand Hasselblad at Uni, but sold it after leaving to raise funds for racing, stupid idiot I was. Still have my old faithful, although not so faithful anymore, Pentax ME Super but the shutter's jammed and I think it's not cost effective to get it repaired.

Looking at the Canon D550 soon
