thank you.
I thought canon lenses were not possible but hoped nikon ones would be. But I found there is a pentax version of this lens, they just dont come up for sale as often, guess i will have to be patient

I have noticed there are some cheap lenses for nikon aroumd 400 mm fairly cheap. cheaper than anything I can find in that range for pentax.
example £200 Tokina AT-X AF400mm F5.6 Prime Lens
I think I can get an adaptor to fit nikon lenses to my pentax ks2, has anyone any knowledge, regarding if this works and is the lens I have seen any good. orany good alternatives.
I am quite happy to manual focus auto aperture is important though.
thank you for any thoughts.

I took this picture on holiday in the summer, In Rhodes, but I have some dirt on the lens or sensor that has made dark blobs on the picture.
I would likle to do an a4 print butI am not skilled enough to fix it.
Has anyone with the skill got any spare time to fix it for me please.
thank you Steve.

Thank you everyone, lots of different ways to find the distance, i played with the DOF calculator, and the distance scale on a couple of my lenses, which I had never looked at before, it looks like the lens is accurate enough measure of distance. I can only guess the distance from home. but if I use my maximum aperture of f3.5 if the boat is only 50 metres out . I would have a depth of field of 40 metres which is plenty for a small fishing boat.I will look at google maps, I can get a good idea of the scale from home.

thank you i will have a look on ebay now. If I have a wide aperture that will increase the shutter speed, If it still blurs I would have to up the iso but I like to leave that as low as I can.

I had a search already I cant see an answer. I want to do a composite picture of a fishing boat going across a harbour. I want the boat in full focus.but the aperture as wide as possible to avoid blur. I have a depth of field calculator but I would need to know the distance to the boat is there an easy way or device I can use in the field to determine this?
thank you
