Help - lens question for stereo print experiment.
I've tried the DA 35mm f2.4 and it certainly works using the Pentax Stereo Adapter, the front ring doesn't rotate and both are 49mm filter thread. It didn't work as well as I had hoped in terms of IQ. It was easy to print 6x4 prints. It's a great lens at a bargain price, welcome to the forum.

SRS Lens prices shot back up!
I was talking with SRS yesterday and was told it is Pentax who have put up their prices, so undoubtedly this will soon filter through to other suppliers once they have used up any old stock

Whats it worth Pancake M 40mm 2.8
So it's pretty much down to compact size. Fair enough :) - although as pointed out most A and M series primes are pretty tiny. The M40/2.8 is halve the size of an M50/1.7 (the closest M lens) and protrudes only 18mm from the mount, even adding a UV filter makes it substantially larger. This makes a ...

Cokin Filters on DA* 16-50
The Cokin P-series are shown to work at up to Ø82mm but in one of the notes it suggest Vinetting may occur on some wide angle lenses greater than Ø72. The DA*16-50 is Ø77 so it falls with that ... Has anyone tried a P-series with the lens set at 16mm? If so, what are the results? And was it...

iq comparison question
From experience, very little, they're both very good performers. The "A" has the advantage of constant f/4 aperture and of course you have AF with the "F" and it's rather more compact, with 49mm filter size as opposed to 58mm with the "A" Both are solidly constructed, the "A" is push/pull zoom and t...

Using UV Filters
Thinking of getting a 62mm UV filter for my new 18 -135 WR mainly to protect it from scratches etc. Does it have any effect on image quality? Any particular makes you are happy with or to avoid? Are the expensive HD versions really worth the extra investment? I would appreciate any input based...

Using UV Filters
Most people here recommend a hood rather than a filter. It's a topic that comes up about three times a year, and the answers boil down to: - Don't use one: why buy an expensive lens and then stick more glass in front of it, given that the coating is pretty tough anyway, and if something breaks...

Using UV Filters
That's a sort of summing up from ChrisA, but to be fair there are those who have experienced filters fragmenting and damaging front elements. I'm not sure that anyone who uses a hood has damaged an unprotected front element. Save your money, unless you are so clumsy that you stick your fingers al...

Using UV Filters
I am of the use a filter side of the argument. However I tend to use a Protector on most lenses although a couple do have a UV. If you do decide to go with a filter then look at: The Hoya Pro1 range (which mine are) http://www.hoyafilter.com/hoya/products/pro1digitalfilterseries/ or the ...

I'm with ChrisA and John on this and have personally had a lens damaged by a breaking filter. I'll only add that the front element is way tougher than any filter.

Using UV Filters
Every piece of glass, no matter how plain and what coating it has, introduces some flair. Compared to nothing any glass is a cloudy thing you put in front of your lens. The only exception is suppose would be a polarizing filter, or special purpose filters and in the old days with a B& W film da...

Using UV Filters
Whilst I'm with John/Chris/Ken/Horst on this I think it's worth adding that there are some rare occations where a filter might be a good idea. If your likely to be getting salt/dirty water spray around (not so rare with WR cameras) add a filter (even a relatively cheap one) till clear of the spr...

Using UV Filters
Perhaps sales people being constantly pushed to sell "add ons" when selling a camera could also be a factor? The profit for retailers could lie in the filter, case, maintenance kit and insurance that they want to add on to every sale.

Thank you all for your input. I think I will leave the UV filter out and may consider keeping one in the bag in the future for use when the situation demands. I feel just the hood or the cap will do for now. Best regards, Gajan
