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)...

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
To expand slightly on David’s last post, the use of the ‘A’ setting in the aperture ring provides all functionality apart from auto focus. This makes for a lens that is quick and simple to use in one the camera programme modes. I have a copy of the 35mm f/2 model: it is one of my two favourite l...

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
You can use "catch in focus" with a manual focusing lens. When CAF is activated, you hold the shutter down while focusing, and the shutter will release as soon as the focus is confirmed.

Carl Zeiss 50mm f1.4 Planar T* ZK on Pentax K5 & Pentax K1
Hello again - by great chance three 35mm lenses were listed previously today on eBay ex-demo from Rare & Mint in Austria (meaning no added VAT versus the one listed for sale from the UK). Ordered one 5 minutes ago. Looking very much forward to receiving it :) I can imagine you're excited :smile: ...

Lens porn - new acquisition
I am absolutely delighted with this somewhat unusual 78mm Trioplan now that I have converted the mount to M42. 75mm is about as short as you can go with these and still get them to focus on a DSLR. With this one I managed to get a helicoid between the camera and the shutter assembly and it still wen...

Lens porn - new acquisition
I was going to take it out on a walk but the weather has been dire! Consequently, I have been stuck with the garden and its proximity to the kitchen door and a paved path - the lawn is too soggy to walk on.. 1. We have a nice double camellia in the garden that is within reach. The flowers are abo...

Lens repair
Hi fellow followers, I have a slightly sick DFA150-450. It records 310mm to the taken file regardless of the focal length. Also for a long time now it hunts for focus, not in a “can’t find the target” way more in a sickly focussing physical way. It’s never been banged or dropped ever so has to be so...

Lens repair
There's usually a fork contact piece that controls the zoom and focus data. A damaged contact or trace would cause the hunting issues you're seeing. It's an unusual problem to come across if the lens hasn't been disassembled or dropped! Good luck with finding someone to sort it out.

Trying Out a Cosina 20mm f3.8
I recently bought a Cosina 20mm f3.8 from E-Bay, despite the many reviews of this lens saying it's basically rubbish but hey! I don't listen to that, I like to make my own mind up. Anyway, I took a couple of photos in my back garden and I am very pleased with my purchase and maybe one day I will get...

Trying Out a Cosina 20mm f3.8
The Pentax DFA 21mm f2.4 is just about the pinnacle of quality for a prime at this focal length (give or take a millimetre) and at wider apertures the Cosina is no real match - but stop it down a bit and it's well capable of producing some very nice results. Bang for buck it's worthwhile having it i...

Not bad for a lowly kit lens?
Glanced out of the window just now and saw a nice clear moon.... So thought I'd see what I could make of it with the previous generation non-PLM HD DA 55-300. Getting it to focus accurately required a bit of effort but we got there and, given the lens isn't really suitable for this kind of shot, I'...

Not bad :smile::smile: Try using a Bahtinov Mask for focus. Use it on a bright star. Then point it at. and shoot the moon.

The M 40mm lens
Is this the pancake lens? It was the first lens I had with my K1000. I was happy with it but had to sell in part exchange for a new Pentax camera with built in self focus (can't remember whic) and missed it.

Manual Primes Thoughts
Long time no see................ ! Feeling I have barely done anything of worth with the bunch of dust collectors on the shelf (been far too hot this summer in Hungary to actually do much more then the office job) I think I realised I was jaded. To combat this ennui I pulled out some old prim...

Manual Primes Thoughts
Welcome back. Looking forward to seeing a photo or two from your new-found enthusiasm for older lenses :smile: . Just a couple of thoughts before you decide whether to sell your AF lenses. First, if any of them is a macro lens, keep it - if manual everything takes you towards macro (which is mai...

Manual Primes Thoughts
Always glad to hear of people enjoying fine manual focus lenses. I'll add a comment on the AF lenses - maybe you just don't have the right AF lenses for you. It sounds like you want a 50mm and little else but have been drawn into buying some lenses you don't need. I'd recommend a 35mm lens for ...

Sigma 150-500 hsm os /sigma 50-500 hsm os
I have the 150-500.... It has served me very well over the 15 years I have had it, and it has taken all the abuse I have given it! Strong and sturdy is what I call it.... It even survived a fall, but the camera is was attached didn't! People say it can be soft at 500mm, but I have taken pin sharp...

Latest Meyer Optik Trioplan conversion.
Everyone knows that Trioplans cost an arm and a leg. Most of them come in Exakta mounts and they can't readily be converted to something we Pentaxians (or any otherians) can use. Enter the standard 'between the wars' bellows camera! A lot of them look like they've been in the wars and, like the one ...

What can I expect from a K-1 and legacy lenses?
If you haven't already, and I guess you have, check out the review section . A fair share of the reviews are of old lenses mounted on a K1. A thing to consider is whether the lens 'communicates' with the camera, so that aperture mode and others work. As far as I understand, and I could be ...
