To be more precise:

The focal length of the lens used on a full-frame sensor or an APS-sized sensor is the same (i.e. achieves the same magnification) but since the smaller sensor only captures a smaller central portion of the image projected by the lens, the field of view obtained in the latter case gives the impression that the lens is acting as one with focal length times the crop factor.

It is designed for Pentax digital. However, the focal length for digital cameras is still predicated on 35mm terms. If you put your lens on a full frame (35mm) camera (assuming it worked, which it wouldn't), it would be 16mm.

To get a true 16mm you will have to get a 10mm, or 10.66666 mm to be precise.....

With the 1.5 crop factor of your camera it's equivalent to 24mm on full frame if that's what you are asking?

The histogram should give you a good idea of how accurate your exposures in manual are. I am wondering why you are bothering to shoot in manual at all given that you have a modern dslr? Are you shooting film as well?

The only time I shoot in manual is bulb when it's largely guesswork without a light meter. I don't think you will ever be able to get the same accuracy of exposure that your camera can unless you are using a light meter. That being said, your camera is equipped with one, so why not use it to set exposure?

It seems even snowpersons (to to use their correct, non sexist name) are subject to censorship...




A snowlady that Maria Conneran and her family sculpted in front of their home attracted an anonymous complaint to police who had the family cover up the sculpture with clothing.

Fantastic pictures, I like all of them!

Great capture! Glad to see you are back!

That's hilarious! Sadly, it might just be true...........

Have you thought about a right-angle finder? There's one made by Seagull with +/_ 4 dioptre adjustment, you can find them on ebay. Here's a link.

I read a review of one on Amazon and the person who bought it had fitted it to an ist DS without any problems.
