Can someone recommend a filter for my pentax 16-45.I'm a bit reluctant to fit one really, just worried about damaging the lens.looking to retain SMC coating advantage. Regards Chris

It might damage image quality. Why add more glass that's not needed to an optic that has been precisely designed to maximise image quality?

Hoya or B&W are the best, if you must buy one of those with the coatings.

I firmly agree with John, I would never consider using filters with the only exception of a ND grad filter for greater creativity such as longer daylight exposures. The SMC coating is protection enough from marks etc. If the lens sustains such an impact to damage the glass, then (in my opinion) ...

I use hoya skylights and uvs on most of my lenses because I am a bit paranoid about what happens when I forget to replace the lens cap when switching lenses in a hurry or if it comes loose in my bag, as some of then seem determined to do. I haven't noticed any issues from doing this. But the DA16-45...

I use a Hoya Pro Digital MC UV on mine when conditions dictate.

Hoya also make a "Lens Protector" - it has no filtering characteristics and has minimal effect on quality. It is just there to protect the front element. It is available as a Pro-1 Digital which means it is very thin too. I have one on my 16-50 and 300 but UV0 on my 50-135 http://www.s...

My view: Most of my lenses are old K or M series. I've only had one marked example (which I knew about before buying it). If they've lasted this long unscathed without protective filters then I don't really see why I need to add them.

ensinor 24mm macro lens f2.8-f22.
Thanks again. No big deal. It was a charity purchase and a gamble. I did not win on the gamble but the charity did on the purchase. Such is life. The daylight filter on the lens probably is worth just about what I paid for the lens. regards thoramay.

Sigma 28-105mm f2.8-4 mini review
Picked up this lens from Park Camera recently and as it seems fairly uncommon I thought I'd post some thoughts here. I found the lens buried in the middle of Park's large used equipment list. I don't think it was even in the Pentax section! I didn't know much about this lens but i thought for £4...

new 645D lens?
The speculation go from some kind of shift/tilt lens to a filter insert :|

new 645D lens?
I'm wondering if the bit with "Front" on is removable? Possibly it's for a filter with the little dial being used to rotate things like polarisers and the thumbscrew used to secure the filter holder, like the grip on the old SFX?

new 645D lens?
Looks like a filter insert to me as well (hence the "Front" designation).

new 645D lens?
On about this lens it says under 'other features' "PL filter window for easy installation of a polarizing filter without removing the lens hood " So its almost certainly for a drop in filter as a filter window in the hood like in many DA/DA* lenses still requires removal of the hood to fit/remo...

new 645D lens?
A number of bigger longer lenses have rear-drop in filter slots, and some lenses like my K series 15mm have the filters built in, so that is certainly a possibility. K.

new 645D lens?
To me it does look like something attached to a pre-production version of the announced 55mm lens (screwed into what would normally be the filter ring?) As to what it is and what it does, I'm sure we will find out, but I like the sound of a weather sealed circular polariser, if only cos I just ma...

Danny you don't have all the info but you could use the 645D with the 55mm lens so why mask the focal length on this model? I think it's most li...
