I have never had any problems and can't help wondering if some of the problems are due to buyer naivety or unrealistic expectations. Much of what is sold is at bargain basement prices and from a DEALER. Dealers know the true worth of rare or mint items and would not sell them at rock bottom prices....

Hoya filters - Comparisons of Quality?
Hi Folks Three of my better lenses (Sigma 10-20, F4.5-5.6, Sigma 70-200mm F2.8 APO, and Pentax 55-300DA) are now fitted with Hoya Pro Digital MC UV filters - and they seem to make virtually no (if any) difference to the image quality. However the s/h 100-300mm F4 Pentax (thanks Lenny Boy & f...

Hoya filters - Comparisons of Quality?
Hi, To be completely honest I wouldn't waste your cash unless you are 100% convinced that you need to "protect" your lens with a UV filter - personally I don't use them and only imagine any benefit from them when in extreme conditions. Just my thoughts Simon

UV also does nothing to your photo's because UV is already filtered by most lens coatings and also by the filter infront of the sensor so it's quite useless...

Hoya filters - Comparisons of Quality?
I find lens hoods are best for protection of the front element on the longer lenses. Not so good for that on the 10-20 though. Funnily enough they improve the pictures as well by controlling flare, so a double advantage! The only disadvantage is the extra space they take up when not on the camera...

The best protection for the front element is proper care in use and a lens hood. As has been noted many times, a filter that shatters will likely scratch the front element anyway. A lens hood will take the first knock and thus protect the lens.

Hoya filters - Comparisons of Quality?
I have never had a Pentax bayonet lens hood that has been loose, fallen off or been anything else but solid. Also, the lens hoods that are plastic will absorb impact up to a point without damage. A metal rim filter has no give, so will transmit all the impact to the lens. However, this is all...

I'd imagine a polycarbonate filter would be best for bullet fragments! Does anyone do a plastic filter of optical quality?

Hoya filters - Comparisons of Quality?
filters do keep general "muck", especially dust, off the front elements - so I think I will carry on using them, in one form or another! :D Agreed... I'd much rather accidentally scratch a £30-70 UV filter than a £200-700 lens... I now use Hoya UV's (they come off when using polarizers or ND's)...

then you have no protection. The front element and the coatings today (also 30 or 40 years ago) are designed to take a beating. Also any filter will degrade the image quality, there is no escaping that even if you buy the best (if you see it is another thing though ;)). I always show this movie...

Hoya filters - Comparisons of Quality?
HI, There are very few filter makers who sell just 'protection' filters, I have seen them but not very often, the two I have seen were from Tiffen and also Contax (Contax now only available on the used market). If you require the highest quality filters then you need to go with either of the two ...

Hoya filters - Comparisons of Quality?
I tried a B+W MRC Nano Coated UV Haze Filter - XSDP Mount. Not impressed. Hood would not fit and had faint scratch on it. Got a Kenko Zeta UV - very good and I would recommend one IF you want to use a filter at all

Hood would not fit Why not, it's just a screw-in filter right?

linear polariser ok for autufocus
This is my first post so I though I would throw this one in. I recently lost my 49mm hoya HMC polariser filter and in a rush by mistake purchaced a 49mm Hoya linear polariser. Now ever since I first purchaced a auto focus camera a Pentax SF7 one of the first, I have always been told and have taken i...

Af seems to be okay with Pentax DSLR but the exposure metering is off depending on which angle the filter is it either goes up or down the metering fault.

Recommendation ND Grads (cheap as chips eg ebay)for beginner to purchase. Intend to experiment with coastal landscape (lots of sky and sea). I have Cokin type filter holders. Regards Stan

Rocky Cameras??
Oh well, the Voitglander Vitessa L should arrive tomorrow. Hope it works properly! The Vitessa L arrived yesterday and looks GOOD! The Ultron f2 lens is clean, no visable marks, rangefinder clear, bright patch, body has one small dent and a very few flaws in the chrome. Shutter sounds right. The se...

Rocky Cameras??
The Vitessas with the Ultron lens (excellent choice by the way) changed over time from screw-in to bayonet (not sure which came first or if it was an option). I believe the screw in filters were 40.5mm (fairly common for Leica thread mount lenses which were popular at the time) but the bayonet was u...

Hefty1, many thanks for the info. I had just figured it out myself, it amounts to sort of an interrupted thread. Just insert the filter, give a little twist and voila! But of course no one else used such. Ah, the hoods! I've seen what might be such for (gasp!) $60 or so! I guess I'll l...
