SMC A 50mm 1.7

If you have the body on autofocus it will refuse to fire unless it thinks the lens is in focus. Try turning the body to MF and see what happens. Cheers, Kris.

SMC A 50mm 1.7

Kris, Works perfectly - thanks for the advice. Should have thought of that myself (the fact that it's a manual focus lens provides a bit of a clue :oops::oops:) Haydn

SMC A 50mm 1.7

I don't know about the K10d, but if you have 'use aperture ring' enabled and hold down the shutter button, then slowly turn the focus ring on a 'm' lens,when the centre comes into focus the camera takes. Works on my K110D and K200D.

5/500mm Takumar Experience Needed

I should imagine that it's pretty good optically, but a bit of a pain to use - no auto aperture - so open up to focus and close down to shoot. That said, I usually use my 400mm wide open anyway, and would probably do the same with this. G

5/500mm Takumar Experience Needed

...I can't mount my mirror lens on my K110D due to the flash overhang... You could use an extension tube or tele-converter to get around the "lens too large" problem... A friend of mine found a extension tube just long enough for her setup, and leaves it permanently attached to the mirror... I g...

Wide Angle Prime Lens.....

I recently bought a Sigma 10-20. Am delighted with it despite some reservations at the time. My preference from online research was to get the Sigma 12-24 buts its a bit too expensive. I tried the 10-20 in the shop and it seemed reasonable. Since getting it home and using on my own camera(I did have...

using manual lenses on a digital body

Well, being dyslexic just adds to the fun: Its Easy... the front thumb wheel is for shutter speed, the back button is for aperture, or is it the other way around? No that was right, but only for the AV its the other way around for TV modes, and maybe the SaV mode... No wait, that's TaV mode. SaV ...

using manual lenses on a digital body

not sure about the k200, but the k100 works as follows... depending on the mode, of course. in AV the little thumbwheel at the back on the right controls the aperture (using an A lens). twiddle it and you'll see the setting change in the lcd screen and the viewfinder (obviously not both at the...

Zoom Lens + TC - which combination?

If you go down the 70-200 route, be aware that there aren't any teleconverters yet that work satisfactorily with the Sigma 70-200 f2.8 HSMII. The Kenko 1.5x (but not the 2x version) and Tamron 1.4x work up to a point, as they have 'SDM/HSM/Power Zoom' contacts in the body, but autofocus on C-AF i...

difference between pentax-a and pentax-m lenses

Thanks for reply and clarifying re Lenses,wasn't sure if M42 & M were same fitting as I got caught out with an older lens my Son had on his old Pentax that looked same as std kit lens but when I tried it on, could not get it back off. Had to send camera to UK to have it removed. So the essential ...

Mirror lenses ?

A good mirror lens will produce excellent results, albeit with the characteristic "doughnut" appearance of out of focus highlights. Unfortunately there are lots of cheap and not very cheerful mirror lenses, usually 500mm. Many cost £99 when new and have dire optical qualities. The Tamron is a ...

Mirror lenses ?

I owned a Tamron SP 500mm mirror lens, arguably the best of the bunch (other than Pentax), for many years and seldom used it. I've since sold it and much prefer to use shorter focal length lenses. I have the Tamron and it gives great results, some are posted on here. A lot of the problems with Mirro...

Mirror lenses ?

i've got the Tamron - i got it back in the film camera days. plus points - it's fairly small and not too obtrusive. the image quality is great*. the background can be used to artistic effect. minus points - you need lots of light! focus range is very small. i've used mine for wildlife shot...

SMC PENTAX-F 50mm 1:1.7 autofocus

I've just sold mine on... it's a very different beast to the f/1.4, and for most of my photography the f/1.4 got used (hence the reason for selling the f/1.7). The 1.7 has a flatter field of focus, could well be slightly sharper than the 1.4. It also has 6 aperture blades, and I prefer the octago...
