Using UV Filters
I always leave a UV filter on my lens unless I'm specifically aiming to get the absolute best photograph I can. I always get a filter with every lens I buy as you can often get a deal on the filter price. I would love to claim that a filter would have a detrimental effect on my images but 80%+ o...

Using UV Filters
I always leave a UV filter on my lens... For me the risk of goo on the lens and the slight chance that the filter will cause more damage than the impact that broke it are much higher than the risk of a minimal reduction in image quality. But that's just me:D I quite agree.

Using UV Filters
Only have one screw in filter and that is a Hoya CPL. All three of my lenses are 62mm, so just one filter needed. I use to stick a cheap UV on all of them up till last year but then read i was probably degrading the IQ, so ditched them all. Just make sure a lens hood is in place unless using the C...

......... but then read i was probably degrading the IQ, so ditched them all.......... I hate to sound controversial but didn't you check? :shock: Personally I can see no detrimental effect when I'm using the filter and the odd occasion where I 'think' it might make a difference I take it off. ...

Using UV Filters
I use filters on most of my lenses. Primarily to stop me having to clean the front elements (and risk scratching them in the process) more often. I'm more concerned about finger prints or marks than impact damage. I've never tested the IQ with verses without - there are so many more important basic ...

Using UV Filters
In my case camera with lens rolled slowly off the top of my bag (8 inches?) onto a thickly carpeted floor. fragments of expensive filter embedded in front element. Lesson learned.

Using UV Filters
I always leave a UV filter on my lens unless I'm specifically aiming to get the absolute best photograph I can. Why would you not always aim for the absolute best photo you can take :?: Personally I would rather run the (slight) risk of damage than knowingly take pictures that might not be my b...

Using UV Filters
I only ever use a UV filter if i think the situation requires it. Such as down the beach with salty water or on a lens that has no hood. I had a Canon lens damaged in a museum by a clumsy oaf with a rucksack a few years ago. Barged by and the metal buckles ran across the lens. Lovely scratch acros...

Consolidating my lens collection . Good Idea?
Hi all, through my years with Pentax several lenses I eventually put together this 8-lenscollection: SMC DA 15/4 Limited SMC 'K'20/4 SMC 'K'30/2.8 SMC FA43/1.9 Limited SMC 'K'50/1.2 SMC 'K'85/1.8 SMC FA 135/2.8 SMC DA 17-70/4 I am more-less decided to let go of zoom, although it is nic...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
With the dust protection system for the higher end Pentax bodies in particular (similar to the Supersonic Wave Filter offered by Olympus and Panasonic) it really should be a non-issue. I have only ever had two or three specs of dust (and that includes going on safari and changing lenses (not we...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
I used to have a K20D which I used with various Pentax lenses (none of them fully weather-sealed) and I occasionally needed to clean dust off the filter, particularly after changing lenses several times in the field (never had problems with dust getting inside the lens). I've had a K5IIs just over ...

Sharp Long lenses for my K-30
Sharpening in post? pah, if your lens is soft or has poor resolution, you're stuffed. Agreed, if the lens has poor resolution you are stuffed. But if it is soft due to poor contrast you can often work wonders in PP. And if it is an older non APO lens that has poor contrast primarily because t...

Thanks Gary. I had a look at your link. Wow what great pictures. As I said, I will Load my Film camera with a real of B&W film. And screw a yellow No1 filter on front and see how it goes . I found a place in St.Kilda which looks very interesting for developing the B&W films. . Regards, Horst

My new aquisition.
Today we celebrated my birthday and the grandchildren came. So I made some portraits in our lunchroom with this lens. But i screwed a soft focus in front of it. Here are a couple of the results. Both pictures where taken with natural light. Next time I try it without filter. My Grand daug...

AF Adjustment
Regardless of whether you can accurately calibrate a lens at all focal lengths (which you can't), calibrating your lenses to each individual camera body is a must if you are interested in ensuring you get the best results from your lenses. I've owned 9 Pentax DSLR's and a K-01 and the only one th...

AF Adjustment
I've owned 9 Pentax DSLR's and a K-01 and the only one that hasn't required any lens calibration is the K-01, purely due to the AF method it employs. There has been massive variation between K-5's and to a lesser extent with K-5iis and K-3, but all have required individual calibration of each lens....

A weak lens...
my vote for f-series http://kmp.bdimitrov.de/lenses/primes/wide-angle/index.html The Pentax SMC-F 28mm F2.8. This was announced with the first of the Pentax AF cameras back in 1987, and only produced until 1989, when it was replaced by the FA series of lenses. So, to start with, what do you g...

Pentax 50-200 WR- user experience
Is there any differenc in te optics in te DA50-200 and DA50-200WR? The WR version is 2mm greater in overall diameter and 1mm longer but uses a 49mm filter compared to the 52mm on the non-WR. The slight increase in size may be (probably is) due to including various seals, but the reduction i...

Pentax 50-200 WR- user experience
I'm pretty sure the lenses both have a 49mm filter diameter.
