The Dreaded Fungus
Hallo... I have the same problem as Kim. I have fungus on the second element. It is just a big dot for now but it's disturb me. I was thinking if I can just unscrew the first element (first lens) and clean the fungus off with the small piece of cloth and the lens cleaner? What can go wrong? Perh...

Filters and flare?
Pentax lenses are noted for being very resistant to flare, but does using a cheapish skylight / UV filter (to protect the front element) make flare more likely? Is it best to remove the filter for critical shots, or worth investing in pro standard filters to retain the pentax lens performace?

Filters and flare?
Why use a cheapish filter? You wouldn't use a cheapish lens. Good quality filters,(not so cheap)have very good coatings and don't add much or any flare to it, especcialy if you use a good lens hood. The best one is the one made for the particular lens. My advice: Don't worry to much about the filt...

Filters and flare?
I think I'd rather my £20 filter got scratched than my £700 prime lens!

Filters and flare?
The basic idea of an UV filter was not to protect the lens, but to reduce the bluish tint of the UV rays. However modern lenses often have new types of glasses which don't require filters anymore. (Specially late Leica lenses). Nowadays they used just to, hopefully, protect the lens. Lens hoods...

Filters and flare?
The main thing a filter prevents, which a hood can't, is cleaning marks. Cleaning dust or moisture off a 'sacrificial' filter means you don't need to be quite so careful, which is great if you need to have a quick wipe when out and about. I uncapped my DA15mm this afternoon, and found the front elem...

What is your favorite lens?
I guess it depends on what I'm trying to achieve at any one time, but I do have a soft spot for my SMC Pentax-M 20mm f4, usually with a nice red filter sitting on the front. The film will be Kodak Tri-X developed in Paterson FX-39 and printed onto Agfa Premium Multicontrast paper. Lovely!

What is your favorite lens?
I have to agree with John Riley; my favourite lens is my Pentax SMC M 20mm F4. It is a very small lens, with great wide angle and depth of field. I keep a Cokin P filter holder, with a Cokin Circular Polariser, permanently attached. grahamwalton

Hi I would heartily recommend the 50mm, I have the FA 1.4 and the K-series 1.7, both are fantastic lenses - whilst the FA 1.4 doesn't really appear second-hand very often (I struck lucky, £60 with really good UV filter and hood from Jessops, of all places!) the K f1.7 is everywhere, you should be...

Zoom tele lenses and fisheye
I can't comment on the 75-300mm lens, but I expect Pentax lenses to be of a good standard. As regards a fisheye, you can get the result very cheaply by buying a fisheye converter, which is an auxiliary lens that fits into the filter thread of your main lens. With a 28mm it gives a fisheye effect. Wi...

50mm+ Zoom for *ist D
Malcolm, I'm in exactly the same situation. After some research, my lens "hit-list" is as follows: 1. SMC-FA 24-90/3.5-4.5 AL IF - has the same filter size as the 16-45, and is lightweight. Image quality is amazing. But expensive. 2. SMC-FA 28-105/3.2-4.5 AL IF (note the AL) - there are a few...

pentax k1000 lesn cap
First check the filter thread size for your lens (Probably 49mm) and then order a lens cap. The body cap is to put on the camera body if no lens is fitted. A rear lens cap would be to protect the back of a lens that is not fitted to a body.

pentax k1000 lesn cap
After losing a bunch of lens caps I bought some OpTech Snap Caps. There are two kinds. One screws on over the lens or filter. The other has a ring that goes behind a filter. They work great, providing the lens doesn't have a lens hood. My 50mm walk-around lens lost a few caps but now I pop the cap ...
