Some more uses for a lens Hood
The main purpose for a lens hood is of course to cut down the glare caused by angled light waves hitting the lens However there are other handy uses especially with lenses where the front element rotates during focussing. The auto focus lenses all seem to have a very narrow focussing ring on fro...

Any experience with the Pentax-F SMC 85mm F/2.8 Soft Auto Focus lens
I've used the 85mm f/2.2, but I was uninspired by its possibilities. The lenses are quite rare and very expensive as a result. In the version I had there was an adjustable baffle that increased the soft focus effect. I'd rather have a standard 85mm and use a soft focus filter or digital effect th...

Pentax SMC DA* 16-50mm F/2.8 ED AL (IF) SDM
Hi Pirate, The 16-50 lens - buy it - if the results are not up to scratch that is the user not the tool and that is the same for all the fantastic DA* range Have no illusions the DA* lenses have cost me a fortune; I am a working photographer of 50 years experience who due to photographic n...

Interest Check: Tamron 18-250mm
I've recently bought the newer version. Was going for your version but a free filter from Sigma and extended warranty swayed me. Getting on great with it on my Kx mainly or K5. Seems to focus faster than my DA55-300 with the wide option when needed. http://flic.kr/s/aHsjEyoiWS See some pic...

Ultrawide rectilinear lenses for Pentax
They're a nice lens Here's mine, previous owner blacked out the lettering on the front because it reflected in the filter. John

On my first camera (K-x) I had the same problem. No issues with the same lens on all subsequent cameras, it is sharp as a knife. This proves the camera was the issue, not the lens. Since then I've had two K-x's, a K-m, a K-5 and a K-5IIs. The K-5 required quite a bit of AF adjustment with all ...

Also, try your 55-300 without a UV filter. I think you might be surprised how much difference this makes. Regards David

David is right. The problem you seem to have had was exactly the same for me. I was given a UV filter when I bought the 55-300 and it would not focus. I took off the filter and the lens worked perfectly. Sorry to hear about your disaster.

so, just taken the camera through some tests: 3 shots at 300mm f5.8, f10, f22 with UV filter, 3 shots 200mm at the same f stops, then 6 shots again without the uv filter. The results very interesting. No noticable difference with or without Uv filter, but all shots taken at f5.8 through all focal le...

lense choices for lanscape - filter suitable. Legacy options.
Hiya in need of some advice - I spend probably 50% of my time on landscape photography, the rest mainly on street photography. I'm off to iceland in 6 weeks, and really want to emerse myself in some lanscape photography. I also think filters are the way for me - I spend so much time artificially ...

Sigma 24/2.8 Superwide II perhaps. John.

Have you considered the DA 35mm F2.4 - only £129 at SRS, and it seems to get excellent reviews. You could then get the 21mm Ltd, and you would still be able to use a 49mm filter mount on all your primes. Philip

If you are looking at a manual focus prime which will give you 'bang for your buck' I would look no further than a Pentax-M 28mm F3.5, or even better a K 28mm F3.5 if you can find one, although the K will cost more. I have the M version; a mint one cost me £30. It's a great little landscape lens a...

Thanks for the suggestions I had a look though your landscape stuff David. Very nice. I noticed you used the 16-45 as your go to lens. The few with the 28mm stood out though, seemed really contrasty. Is that a characteristic of the lens or post processing? 35mm is a possibility too, of course,...

Hi Ian, thanks for looking at my images. The 16-45 used to be my 'go to' landscape lens and I loved it. However, I bought a 17-70 a few months ago and can confirm that it is better than the 16-45 (sharper, better range, less chromatic aberration, better bokeh, better build). I do treasure my ...

There's an interesting bodge for a 12-24mm lens that you may be able to adapt to your Sigma 8-16mm. Otherwise, as you evidently like wide, the Sigma 10-20mm f3.5 might be worth investing in. The previously mentioned Sigma 24mm f2.8 Super-Wide II is an excellent lens too, but perhaps not as wid...

I could quite happily take just the K28mm f3.5 for landscape work in Iceland. It will be fine with filters, taking whatever system you decide on. As with other K series lenses it can be prone to cool colours and show a touch of violet sometimes.
