Non SMC lenses
Short answer; no. A filter won't help as it will add an extra glass surface for light to flare off, hence it'll only tend to make things worse. A lens hood, on the other hand, will do wonders for flare by stopping light reflections striking the lens in the first place. In summary: Buy a goo...

Non SMC lenses
It's not the UV that it blocks that you want a coating but it makes the light travel easier into the lens. A filter with a coating will not help you with that I believe.

Lens hood - what's this bit for?
It's so you can spin round a polarising filter (if you've got one fitted), without taking off the hood.

Pentax 70mm F2.4 limited for £344
That I don't know. I only once bought a Hoya filter from this company via their occasional ebay auctions. Argos, of all places, has the lens for £379, btw.

Actina Thread size???
I have an ancient Actina Polariser which uses an Actina Step ring to adapt it for my 49mm filter ring on my 50mm A lens. I want to fit the polariser to my 52mm DA lens and I want an appropriate step ring (right name?). The o.d. of the filter ring seems to be about 59mm but is it likely to be a thre...

Actina Thread size???
Look for SRB on the web - they make every kind of adapter you could wish for and they may well know the thread size of your filter.

Actina Thread size???
Your Polariser will almost certainly be a 58mm thread size as 59mm would be a non-standard size (measure the outside of the thread, not the filter itself). do 52-58mm step rings for £4.90 :)

Tamron 17-50mm f2.8 XR Di II LD
About build quality I've heard people complain of barrel wobble, and filter ring wobble. Supposedly neither issue affects image quality, it's just disconcerting. Mine has no barrel wobble, but the filter ring does flop around a bit if you wiggle it. I haven't noticed any IQ problems from that. Other...

Pentax DA 18-250mm vignetting
Instead of cropping, you could lighten the corners with a program like Silkypix. This tends to effectively cure the problem. Vignetting should not be bad at f10. Do you have a filter fitted? It could be too thick.

Pentax DA 18-250mm vignetting
Have uploaded a sample pic to my portfolio as I'm not sure how to stick on in here. It had an Ultra Slim UV filter on the front. Take a look and see what you think. No lens hood on it at the time

Pentax DA 18-250mm vignetting
What type of UV protector do you have on. I found with my 16-50 DA, in certain shots at 16mm vignetting was present with a standard UV. I went out and purchased a slim line UV filter made by hoya and haven't had the problem since.

Pentax DA 18-250mm vignetting
It's not vignetting: that would be dark, and this sample isn't. It is an issue with the 18-250 though, but Pete has got a slim filter so he's done what he can to minimise (other than not have a filter at all).

Pentax DA 18-250mm vignetting
What type of UV protector do you have on? It had an Ultra Slim UV filter on the front. I was wondering if Pete might have had white gloves on, they may have been enough to provide the whitish vignetting, if they were only just encroaching on the frame. Bit of a long shot though. :-) Dan

Ricoh XR Rikenon 50mm f2
I'd be surprised if there are any 1970s onward 50mm primes which aren't very good to excelent. I think that's spot on. It's probably also true to say that just about all 50's are better than any of the photos that I'm likely to take with them. :) FWIW, I bought the Rikenon f1.7 off Ebay in the...

New uses for old lenses
I've got an old Soligor 135mm 2.8 that is ( in my view ) a nice lens, especially for £3, a Super Travenar 28mm 2.8 that cost £2 which is decent enough for the money, a Helios 44-2 58mm f2 that is wonderful, for free it's superb but I wouldn't be dissapointed if I'd paid money for it. And best of a...

Pentax Lenses for Dummies
You wouldn't be able to use a hood or a filter on it for that matter, so that huge front element would be somewhat vulnerable. It would be a great lens for taking shots of your shoes, and you wouldn't have too look down to take the shot. :lol:

Pentax FA* 600/4 ED [IF]
A cheaper option, once you've got a 67 to K adaptor: http://www.lcegroup.co.uk/SHdetails.asp?Item=17275 And a review of it here: http://www.luminous-landscape.com/reviews/lenses/600mm.shtml 170mm front filter? :lol: And a 77mm rear mounted filter! :shock: Dan

telezoom choice
Now I preface this by saying that I am a newbie, and the information below is purely anecdotal. There was not a lot of science in my tests, just my observations. I recently bought the SIGMA 70-300MM F4-5.6 SIGMA APO DG MACRO to go with my K-x and kit lens. IMHO this lens has amazing IQ, with litt...

K18/3.5 experience anyone?
I had one, albeit very briefly, I picked it up along with its big brother the K15f3.5 as part of a job lot, exceptionally well made lens and heavy, it comes with its own built in filters, attaching standard filters causes vignetting but I didn't have a thin pro filter to test on it. I sold both...

K18/3.5 experience anyone?
It was taken on my K7 and as I recall it was a very bright day so I put a 58mm Hoya uv filter on it and it vignetted quite noticeably, I assume thats why they put in the built in filters. You can see the flare in my pic, notice that red reflection at the bottom right. I am not even sure if you can p...
