K100D 500mm-600mm Telephoto for Surf Photography

Hi. I am interested in taking surfing photos from the beach. I have a Pentax K100D. From what I have read I should probably get something in the 500mm - 600mm range. I am looking for something more entry level than high end/professional.

I would be extremely grateful if someone could point me in the right direction for a suitable lens that is compatible with my camera that I can purchase easily within the UK at a reasonable price.

Thank you in advance.

no point getting anything that long, and you wont find anything "entry level" in that range. Are you joking? I have done surf photography, from a beach,, and you dont need anything like that unless you are trying to get peoples faces.

Go for a 300mm, either the pentax 55-300 or the sigma 70-300

the pentax DA* 300 might also be good for its weather sealing against sand and water

500 or 600, I'd say the Sigma range would cover it for you, but even 2nd hand, its going to be quite a lot of money. Also remember the hassles in terms of weight and setup/portability with those bigma's., and you will DEFINITELY need to tripod it up very sturdy.

If you are willing to consider your 1.5x crop factor, then a 300mm would "seemingly" produce 480 mm...
I have a Sigma 70-300 APO, and I am really happy with it, I don't do surfers really, but I do airshows and offroad bike races, and it does wonders.

But shop around indeed, anything new for a pentax mount will work on your camera

Thanks for the replies. I have read quite a few posts on here and on some of the surfing forums about the Sigma Bigma 50mm-500mm which seems to get the thumbs up all round. If I can afford it would this be a better option than one of the 300mm options.

PS: What do all the letters after the lens mean??

If you don't mind manual focusing, you can usually find a manual 400MM lens fairly cheap on eBay, or on here. I bought a Vivitar 400mm from one of the members here, and it is a nice lens, a bit heavy, and totally manual, but once you get it dialed in, it can produce some nice images.

Consider one of the mirror lenses. There are a large number of 500mm f/8 mirror lenses out there, and several 600mm f/8 as well. These are not perfect; the specular highlights will show as doughnuts, there is no ability to adjust the aperture, and they can be very touchy to focus. However, you can pick up a good one (check all the reports before buying!) for much less than $200, and often less than $100. As the mirror lenses can go out of alignment easily, ask for images taken with it before buying, or buy from a reputable used dealer such as KEH in the USA.
