Are you talking FF or APS-C, and what sort of money do you want to spend? For FF the Pentax 85mm f2 is a well thought of lens... https://www.pentaxforums.com/lensreviews/SMC-Pentax-M-85mm-F2-Lens.html ..and has dropped in price from up to £200 a couple of years back to between £100 and £150. T...

There is an FA 85mm soft lens for sale at Ffordes if anyone is interested. I was tempted but think I would rather get softening in Lightroom, but softening isn’t apparently like out of focus it just diffuses the light whilst retaining definition and works best with back lighting; Lee Filters do a ra...

[quote:3496ace15f="PRYorkshire"]For me it is the 50mm f1.7. On both the istd and K70 this seems to give the best results. Probably best on istd as can be a little too sharp on the K70. Paul Are you talking of the 1.7 50mm lenses the old manual focus lens? No the F 50mm 1.7 lens. I also have rece...

DA*60-250 owners
Well I have the DA*300 and the 60-250. The DA* is sharper and quicker to focus, but the IQ from the 60-250 is not bad at all and it is perfecty useable wide pen. I actually use the zoom on a K1 in FF mode, I have not removed the internal baffle so there is always abit of vignetting, but as I tend to...

DA*60-250 owners
This one to check for front or back focus - seems to be quite accurate but lacks sharpness at the point of focus. Distance about 2m. Took a couple at about 3m with same results. I also took some shots of a car number plate at about 15-16m. They were not impressive so duplicated them after m...

Can you link to a full size image, cannot tell anything from that size image I am afraid. It may be you have a bad copy. Certainly the answers here suggest the IQ of...

Pentax 60-250mm baffle 3D printer
Does anyone know anywhere in the UK where they do 3D printing of the rear baffle as I saw on the PF site several versions but the best being the one with the square cut out of the baffle. Seems there was someone doing it a few years back but in the US. Thanks.

Pentax 60-250mm baffle 3D printer
Just a follow up, I did a little video yesterday https://youtu.be/4lZ0IXgEfwM Basically I bought another rear baffle from JPTechnical for £16 delivered. Did the same as the first in terms of splitting the 2 parts of the rear baffle but as this was a spare I took a metal file to the lip whilst ...

One lens does all
A very old (1st gen, I think!) Sigma17-70 "does it" for me - dirt cheap from a fellow PU member several years ago, and it's very sharp, quick to focus and reliable, and has proven a very capable day-to-day "do it all" tool :D.

Testing an smc F 70-210mm
When I enquired about affordable lenses for my new K1ii Forum member davidwozhere recommended I look for an smc F 70-210. Well, I found one and it arrived this week. Before putting it to work on the K1ii I thought I'd first give it a test on my trusty K50 and the shots below were taken today. The...

The SMC Pentax-F 1.7x AF Adapter
Many of us have a converter or two as a "cheap" option to extend the range of some of our fine lenses. Much discussion has taken place regarding IQ degradation, AF lock, and the like and we have reached our own conclusions over which converters are worth the compromises - but one converter stands ap...

The SMC Pentax-F 1.7x AF Adapter
If you have an AF lens attached to this converter, does it pass the focal length back to the camera of can you set it manually like a manual focus lens?

If you have an AF lens attached to this converter, does it pass the focal length back to the camera of can you set it manually like a manual focus lens? The FL is set manually, I believe you have to factor in the 1.7x increase yourself. It makes picking certain lengths a little bit awkward. As an ex...

An alternative 28-105 for the K1 ?
When I moved up from APSC to FF my problem was that none of my favourite DA lenses are FF compatible so I embarked on a search for a lower cost alternative to the advertised 'Kit lens' for the K1 family i.e. the D FA 28-105mm F3.5-5.6 ED DC WR. I came across a Sigma 28-105 UCIII AS IF which, apart f...
