Petal lens hood clip out section ?
It's so that you can rotate a polarising filter with the hood on. Tony Tony - Thank you - what a sensible idea and so obvious now you have pointed it out ! I've not used a polarising filter with my digital camera [K10] although I have one for my old ME Super. I may invest and have a play. Thanks ...

Help required from those with knowledge of fa/faj lenses
Thanks for all the help guys, just back from having a play with the lenses. In the end didnt go for either, took the mirror lens instead! Its a Ranger branded one, made in japan, seems better quality than the centon ones ive looked at before. It was cheap anyway so not that bothered, i'll just hav...

Long Distance Wildlife
Guys, I have a Pentax K10D and need a good lens for taking wildlife pictures. Mainly they are dolphins - so shots of fast moving animals taken from a moving ship at a distance of 800m to 2km, at sea (so some glare) I've narrowed it down to either: - Sigma 150-500mm f/5-6.3 DG HSM or ...

SMC Pentax-DA 40mm f2.8 Limited
I bought my K5 about a year and a half ago together with the kit lens. A couple of days after, I also bought the DA 40mm f2.8 lens. Why, It was a spur of the moment thing. I was a bit fascinated by the small size of the lens. However, I never used it, until today. I went for a day trip and ...

What lens do I need?
Thanks everyone for your suggestions, I have bitten the bullet so to speak and have bought the Tamron AF70-300mm F4-5.6 Di LD Macro 1:2 (well that's what it says on the box anyway!!) Bought it in the local shop which was a tad more expensive than on the internet, but I was able to test it out in th...

My 28-200 how many versions are there!
Ok leaves me puzzeled then , been through my holiday images some are very good, some just lack any definition, do you think the uv filter could be causing image quality breakdown?

My 28-200 how many versions are there!
Is there any common factor, such as images taken into the light being less good? I'm wondering whether you can pinpoint that the light coming from a particular direction causes internal reflections in the lens? The filter could be to blame, especially if you don't use a lens hood. Modern lenses h...

Lens Comparison - Advice needed
My initial reaction to these is that Lens 1 seems very slightly better, but it really depends on how they both perform generally. CA aside, maybe for more usual subjects one would be clearly better than the other. For example, a front lit bit of architecture, or a portrait. I'd really want to use...

Lens Comparison - Advice needed
Based on these limited tests, I'd probably go with Lens #1. However, as I've found there's more to a lens than sharpness and bokeh (in these circumstances). I once did a casual test between the FA 31 Ltd, and the FA24-90 and was pleasantly surprised by the 24-90. Certainly saved me a lot of angs...

Canon to Pentax converter
No, unfortunately not. You can get adapters that go the other way (Pentax lens > Canon body) but not what you're after. The Canon bayonet is too wide to go in a Pentax mount and the shorter registration distance means you'd have to mount the lens so far back it would foul the mirror in order to a...

help: dropped a lens, what can i do
Horrid feeling when you bounce a lens, I did it to my Pentax 100-300mm and the only damage is to the hood area where you would mount a filter if the was not flattened in one place - still takes good shots so I have not bothers but it will have made the resale value almost zero I would think. If y...

Tamron 18-250, how's yours?
Had the Pentax version and it seemed good till I got the DFA 100mm macro and I sold it to finance the DA*50-135 since I hardly use that lens. The DA18-250 I had preformed good on my K10D, no focus problems or sharpness issues. I did had CAS though wide open and using it on the long or wide ends. ...

Rikenon 300mm f4.5 APO
I don't know why I didn't notice that. I'm not sure about the wheels, but it's very obvious on the saddle and on the handlebar pin especially. I'm blaming exhaustion caused by gardening and lack of nourishment. :) The fringing on the bike is in the middle of the photo, not at the edges/corners...

Rikenon 300mm f4.5 APO
I took a few more photos this morning, with the Rikenon on a tripod - with and without a Hoya Skylight filter - and also with/without a XR Rikenon 2X converter. I also took some with a 1960's Tamron 400mm f7.5 T2 lens that I acquired for about £20 a while back. The shots were focussed on the tra...

Rikenon 300mm f4.5 APO
The PF doesn't seem to get much worse wide-open than you can see on the bicycle in the photo above. It's improving by f11 and just about gone by f16. A UV filter doesn't seem to affect the PF. A skylight maybe reduces it a little. If it wasn't prone to PF, I think the Rikenon would have been a...

Exposure question
Hi folks, I have a question about exposure. I've noticed that when using my SMC Takumar 135/2.5 I cannot shoot wide open in bright daylight because the photo will be overexposed. Even on the max shutter speed of 1/4000 and at ISO 200 (this was on my K100Ds), I have to stop down to around f4 or 5....

Exposure question
there is no physics involved. We'll have to agree to disagree on this one, I think there is quite a lot of physics involved :) If the results are still overexposed in a normal lighting condition, then the lens is faulty. I don't see how the lens can be faulty. It's fully manual. I can see the i...
