Pentax DA 18-135mm and 62mm, Unusual?
i don't know why, but i have in my head that pentax are 49mm: da limiteds, 50/1.4 fa, 77/1.8 fa limited, 43/1.9 fa limited. to me, what's important is that the standardisation is done according to series. the da limiteds go together, and they all match. that way, one photographer who chooses a se...

Lens Hood for K-X ?
OK, I'm baffled. it might be that Currys had a deal with Pentax not to supply the hood. (EDIT - Should have typed faster) You have various options. Buy the official Pentax hoods (which will help with long-term resale value), buy an aftermarket hood, or buy a universal hood which fits the fil...

Lens Hood for K-X ?
My advice would be to get onto ebay and buy a couple of hoods. Don't just go for the generic ones that screw into filter threads, you can buy copies of the Pentax ones which clip onto the bayonet fitting around the front of the lens. is one for the 18-55mm, is one to fit the 55-300mm. The of...

Lens Hood for K-X ?
It slots over the lens barrel and then clicks into the notches you can see there - it's a bit like the lid of a jam jar or indeed a bayonet fitting lightbulb. This leaves the filter thread free for filters and also means that the hood will stay the right way up (with the longer petals on the top...

Lens Hood for K-X ?
The tab is to allow you to rotate filters - things like a polariser or graduated ND where the effect changes as you turn the filter in relation to the lens.

which Fast Fifty
All are auto-focus auto-aperture lenses (hence convenient) that will take great images. They are so different that you need to figure out your criteria. FA 50/1.4 Compact (220g and 37mm long) time-tested performer. Widest FOV of those you specified. N/A from SRS but cheaper than other choices. ...

Hmm, see, the Dimitrov site lists it for the M 28mm and 35mm lenses with 49mm filter threads?

New 35mm f1.4 MF lens from Sanyang
I suspect they may struggle against the DA 35mm f2.4. Yes this is faster, but it's more expensive and it's also manual focus. What I can't fathom is why other brand forums seem to have an almost visceral hatred of Samyang lenses, even when people here are producing very good results with them. Ag...

New 35mm f1.4 MF lens from Sanyang
I think the biggest issue apart from brand and manual focus may be bulk - with a 77mm filter thread this must be pretty huge compared to Pentax's own offerings at the same focal length. It's closest competitor may be the Sigma 30/1.4 - which is significantly smaller and arguably a more useful focal...

UV filter or No UV filter?
Hi all, I am a new dslr user and have purchased a KX. Now i have been told by some people to make sure i have a UV filter to protect lense and cut out UV rays but i have also been told not to use one as it effects the photo and slight scratches on lense will not matter. Please vote with or ...

UV filter or No UV filter?
UV is already cut out by the lens coating and the filter that's in front of the sensor. As for protection, that's only needed with very old lenses just look at this The front element is very hard to scratch and even if you did you will hardly notice it on your photo, just put a corner of a pos...

UV filter or No UV filter?
I think it goes, Expensive lens why stick more glass in front of it and reduce the IQ. UV is only a problem for film, sensors have a UV filter built in. My UV filter broke the fall of my camera and saved the expensive lens and the camera bounced back up high enough I caught it. I put UV ...

UV filter or No UV filter?
Shops selling cameras and lenses sometimes like to sell "add-ons" to increase the sale with the more profitable accessories. A filter is a handy "add-on" and with digital of dubious value. More relevant is a lens hood, which I think is an essential accessory as it may actually improve the contras...

UV filter or No UV filter?
Thanks for all the info people. I do in fact have a polarizer (hoya) now which i managed to pick up second hand. I think i will stay away from the UV filter and spend the money on a lens hood instead.

UV filter or No UV filter?
There are just a handful of filters that are strill sometimes used. The polariser, graduated filters and Infra Red filters being the most common. These are the few circumstances where it's necessary to apply the filtering at the exposure stage rather than later in Photoshop.
