Neo-retro photography!!

proper retro photography....

Just bought these...

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 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 albeit with loss of some of the camera features.

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

Gotta Pentax K 10D .It can take pentax K mount lenses.Often considered getting some, but never had.

 

[JohnH]

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

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...
http://en.wikipedia.org/wiki/Image_sensor_format

so my 24mm Pentax w/a lens would function more as a 32mm would if fitted to dslr? Pity that :cry: lerve that lens

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.

proper retro photography....

Just bought these...

I'm getting all nostalgic as well, Wu. I've just bought this...

[legrandefromage]

whole bundle of cheap recent Pentax SLR's & lenses at the booty yesterday...

good place to start as any.

 

[Mr Panda]

thanks JohnH - Useful stuff.

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:

thanks JohnH - Useful stuff.

You're welcome!

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

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...

 

[the great roberto]

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
