SMC Pentax A 50mm F2
SMC A 50mm F2 : Got this on ebay recently and am wondering what size lens hood/filter it takes. Also have read a post somewhere saying not to bother with filter just lens hood gives adequate protection whilst retaining image quality. Would be grateful for any advice. Thanks

SMC Pentax A 50mm F2
The A50mm f2.0 takes 49mm filter. You will hear differring views but my advice is get a hood and forget the (protective)filter.

sigma 170-500
Plus the way some annoying dealers spam every catagory under the sun with filters etc. Couldn't agree more. If I want a 52mm filter I will search for a 52mm filter. Attempting to sell me one by clogging up my search results for "Pentax" won't work! Ebay's search thing does seem to deal with "lens...

sigma 170-500
I have one, and have had it for about 3 years. Now if I saw the question last week, I would have said "too soft, lack of contrast, slow AF and noisy" However, over the weekend I can now say "sharp for the price, actually pretty sharp. Good contrast, still sounds like a chain saw....On the whole...

am i the only one
Well, there must have been a rush of buyers, because the only thing there now is a K-x body. :? Dan That one is highlighted yellow on my screen, does that mean that one is still available? For the rest I see these. [For Sale] Pentax 6x7 MLU + AE Meter Prism Finder I have listed this cam...

Short lens with 72mm filter
I'm after some lens advice. I need the shortest lens I can find, with a filter size no more than 72mm, in a Pentax mount. The restriction is because I'll be using it underwater, and that's the restriction of my housing. The structure of the housing also means my 10-17mm fisheye won't work, because i...

Short lens with 72mm filter

Short lens with 72mm filter
Afer looking a bit harder, I've found a useful page for filter sizes . Seems like my only option shorter than I have now is a 16-45mm - is this going to be noticeably better quality than my 18-55mm kit?

Short lens with 72mm filter
When you say short, is this wide angle, rather than lens length protruding from the camera? Just watch the 16-45 as it extends some way out, at the wide end. It is better than the 18-55 but not by a huge margin. The 18-55mm II or WR are both nipping at the 16-45mm heels. Tamron 17-50mm is ...

Short lens with 72mm filter
I think it is noticeably better, but it's not night and day. It's sharper wide open, and there's significantly less vignetting and distortion than the kit. The extra 2mm also gives a nice perspective. It's a quality lens.

Short lens with 72mm filter
If somebody has one to hand it would be interesting to measure it at 45mm and at 16mm just to see the length it extends. Answer at 16mm = 12.5cm at 45mm = 9.3 cm

Short lens with 72mm filter
Yep, should have said I meant short focal length rather than physical length. Maximum length in the housing is 170mm. Might be a tight fit with 125mm of lens fitted to the camera. Does the lens focus internally? Water pressure can put undue strain on the AF system if the front element is moving bac...

Short lens with 72mm filter
The 15mm DA Ltd comes to mind, it accepts 49mm filters. However the retractable lens hood may not retract far enough.

Short lens with 72mm filter
Good point, had a look and it might work - I'll need to try it in person to see if the housing mount can screw onto the lens. I think I might need to do a little saving, or ebay trawling, first - I was a bit shocked by the £600 price tag...

Short lens with 72mm filter
Seems like my only option shorter than I have now is a 16-45mm - is this going to be noticeably better quality than my 18-55mm kit? One thing to bear in mind is that the 16-45's main weakness is very noticeable purple fringing. I don't know if PF is as likely taking photos underwater as it is when t...

The Sigma 18-50 takes a 72mm filter, and also offers a constant f2.8 if required. Adrian
