Pentax 645 120mm 4.0 A vs FA/AF
Clever people, A I got great feedback on macro lenses for a Pentax 645D. At that time, the minium focus distance of the 120mm and 90mm lenses didn't work out. Now I have some new projects where the minimum focusing distance won't be a problem. The 90mm is above budget - but the 120m...

Pentax 645 120mm 4.0 A vs FA/AF
Kasper, have you had a look at the information found here?:- Hope you find the answers you are looking for.:D Thank you for the link :) I get the main difference between 'auto focus' and 'non autofocus', and 'DA' and 'DFA'. But I don't think the overview article has the answer to if both lens ...

Pentax 645 120mm 4.0 A vs FA/AF
"A" series lenses are manual focus. "FA" series lenses are autofocus. Both can have the aperture controlled from the camera body and therefore allow Program and Av modes (with the lens set to the "A" position). The autofocus is the only functional difference though it's possible that some coa...

Will len’s used on a Pentax ME Super work on a Pentax K50?

Will len’s used on a Pentax ME Super work on a Pentax K50?
"I've used Pentax M and K series lens without any problems on my K50" Yep, I should have said, the Ricoh pin problem, afaik, only applies to non Pentax lenses. The Ricoh reference goes back to film days when they made lenses. This has become a generic description; it also affects other lens makes...

Pentax SMC A-1.7 50mm lens
I thought I would get my SMC A-1.7 50mm lens out to try on my K3ii. I've set the F stop dial on the A setting. Set Using Aperature Ring in custom settings. Should I get auto focus on camera, I thought I did on my K5.

Do I really need it
The most obvious item I can see would be a fast 50mm prime. Something with f/1.4 can still be found for pretty cheap, especially in MF. I have a SMC A-1.7 50mm and the M version, but can only use manual focus on my K3ii. If I do get a 50mm it will have to be auto focus.

Re-Think
Right, I'll reveal my approach to the lens collection issue, it might help here. It has at least served me well for many years and will probably last me until the inevitable end. 1. Have a set of general purpose zooms covering wide angle to long tele. This is now Tamron 10-24mm, Pentax 16-85mm and ...

Irix lens repair
Has anyone had an Irix lens repaired? The official service centre is in Poland and that is quite expensive and not straight forward now after Brexit. I would prefer to find a UK repair technician. The lens is the 15mm f2.4 Blackstone and use it on a K1. - I have also checked it on a K3. The len...

Thank you for your replies. I am pleased to report success. I contacted Harrison Cameras as they advertise Irix lenses for sale. They sent it to a repair company they use. I received it back this week, all fixed. I can thoroughly recommend Harrison Cameras. They were so friendly , helpful and e...

How to register a new lens
Under UK consumer law, the retailer not the manufacturer is liable for repairs etc. due to defects. Registering a purchase with the manufacturer is therefore no longer necessary. As others have said, keep receipts and go back to the retailer if the lens develops a fault. This may be different in oth...

Thinking of setting up Lens Buyers Anonymous
Hands up, I'm in... I've lost count how many times I've sold lenses or bodies and then bought them back! Although in self-defense the repurchasing has occurred after having been drawn to the darkside, AKA mirrorless with brands such as Fuji / Olympus & Panasonic. All those brands have been fine, ...

'Hi, my name's Kevin and I'm a Pentax user.' ('Hi, Kevin' from people sitting in a circle in the room.) 'I admit to, (shudder), having sold lenses and then later bitterly regretted it.' (Nodding in sympathy, occasional murmurs, 'I hear your pain, buddy.') 'Even though my preferred format is full...

Thinking of setting up Lens Buyers Anonymous
I have never sold anything (except my Spotmatic back around 1976) As a result I still have everything: A black MX, a silver MX, an auto winder, my original M series lenses, a Zorki 4 rangefinder, a Rokkor enlarging lens, a couple of Flashes, filters and cables. None of which have seen the light ...

Tele-zoom lens advice, please...
Your thoughts, please, on a lens dilemma. My DA 55-300mm (original version), which I've had for a very long time, currently has 2 uses. First, as a small, light weight, 'just in case I need a tele' lens for the bag. Second, as the only option I've got if I think I'll need a zoom in the 100-300mm...

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
Clever people, I'm considering getting a Carl Zeiss 50mm f1.4 Planar T* ZK lens (Pentax K mount). Being manual focus, will it communicate exif, priority & shutter values to the camera body on the K5 and the K1? I have its cousin, the Milvus with my Nikon D3 where all values are passed on to t...

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
I don't think most of those things are properties of the lens (whatever it might be) so there is nothing for it to communicate. They are all generated by the body. What the body will not record is the f value set on the lens (unless it has an 'A' setting. Thank you for the swift reply. So basically ...

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
You didn't say it had an 'A' setting! That WILL transmit aperture data back to the camera and vice versa and you can use AV, TV and TAV, controlling these from the camera E dials. But no AF. You can also use the F series 1.7x AF adapter, if you have one. This will increase the focal length (by 1.7x)...
