Well what D'you know???
I've had 3 Pentax DA16-50 lenses, all 3 have had focus issues even after a full sevice with board and motor replacement, in comparison the Tokina screw drive version has never ever let me down in another marquee. On a side note, the D500 is no more buggy that any other camera but the AF is.... we...

Well what D'you know???
I've had DA* zoom lenses for almost ten years and they have been used extensively so when the SDM packs up (twice with the 50-135mm and now the 16-50mm is playing up) and Johnsons fix them quickly and efficiently I put it down to wear and tear, cough up and get on with it. Paying for the repair is a...

Problems with AF on new DA*300 F4.
Hi I had a quick exchange of forum messages with some users yesterday in and it made me think about some issues I've been having with my new (Dec 16) DA*300 F4 and my older K3. I'm struggling matching the consistency of AF I always got with my FA*300 F4.5 which I've had new since the mid 90's and ...

Fixed Prime Lens
Buy a legacy manual focus prime, Pentax-M 50mm f1.7, brilliant optic, about £20 on ebay or the Pentax-A version for easier exposure for a bit more. Pentax-FA 28-70mm F4 is a great auto-focus zoom, takes great photos, about £35 on ebay. Carl Zeiss Jenas are superb on Pentax, about £30 on ebay....

Fixed Prime Lens
Almost all K mount lenses will fit your camera. If you look for older Takumar or M42 lenses then they will also fit using an adapter (very easy to find). The manual focus 50mm primes would be great for around £25-30 but since the DA50 is barely twice that amount it would be the best choice. It of...

Fixed Prime Lens
Haris, you have very nice stuff on ebay, one being the Vivitar close focus 28mm f2.0 I bought the same lens yesterday and just wondering what you thought of it? I have the same on in f2.8 M42 and it is great for close focus but will sell it if the f2 is better. They are specialist lenses, I've bo...

Pentacon 135mm F2.8 Bokeh Monster Lens M42 Mount
All Meyer/Pentacon 135s will show what looks like 'something wrong' around the inside, just beneath the front element. There is a thin brass shim in there, the appearance of which gets slightly distorted because it is so close to the edge of the glass element. What is on the images here looks a bit ...

Q macro lens?
I suspect your distrust of the Rumours site is well founded John. I have used the Pentax Q adaptor for K mount lenses with the DA 35 2.8 macro, and it is splendid in terms of close up detail, almost like a microscope, but you lose auto-focus and with the metal adaptor and lens this ends up like a...

Vintage Vivitar Macro (image heavy)
I finally managed to get hold of a hen's tooth in the form of a Vivitar f2.8 55mm 1:1 macro lens. Here are a few initial shots with it on a K3-ii. A lot to learn yet but its reputation is certainly upheld so far...... It's sharp wide open - you just don't get much DoF. only one edge of this dhal...

Vintage Vivitar Macro (image heavy)
Thank you for your kind words -- I think a lot is due to the lens rather than me. The grey mottled effect on the 'studio' shots is crumpled kitchen foil sufficiently far back to be well out of focus. The lighting was with a super penlight gadget called 'the illuminator'. Amazon sell them for about ...

Help with a wide angled lens for my K1
One a bit cheaper here: https://www.lcegroup.co.uk/Used/Pentax-15-30mm-F2.8-ED-SDM-WR-***MINT&BOXED***_165205.html Warning - it is heavy, not only in price! If you want a real bargain, seek out a Pentax 18-35 which used to be the kit lens with the initial DSLRs. It is full frame though and per...

Help with a wide angled lens for my K1
Thanks both Johns... Something to think about there.. Though non auto focus lenses arnt much use as you regularly dont get to raise the veiwfinder to the eye and have to use a lot of guesswork... Interesting point on using APSC lenses in the full frame mode.. Is there a listing anywhere as to how...

Though non auto focus lenses arnt much use as you regularly dont get to raise the veiwfinder to the eye and have to use a lot of guesswork... Not really an issue with a super wide. If you want to be inconspicuous the 15-30 isn't the lens to go for as it's quite large. Something like a 20 or 24mm m...

Help with a wide angled lens for my K1
I have a Tamron 17-35mm f2.8/4 I bought a while back in preparation for the K1 but I probably won't be going down that route now so may be willing to part with it. It gets a fairly good write up

Help with a wide angled lens for my K1
Probably was a bit drastic, I agree. But in the great scheme of things. it wasnt just about wide angle lens options. But with more third party lens manufacturers willing to back it. The Nikon D810 is looking a better all around overall proposition. Just a couple of full frame examples... Pentax....
