Hello,

I am a newbie to this forum and really know very little about photography. I recently purchased a K20D with a SMC Pentax DA 18-250 lens. Am I able to get nice DOF photos with this lens or should I look at a wide angle. If so, which lens is recommended?

Cheers,
Carrie

Experiment!! The lens varies f/stop f/3.5-6.3 so at the 50-80mm range it is reasonably open (I'm thinking people/portraits for a shallow DoF); obviously not as good as f/1.7 or f/2.8 etc.

For landscape you typically shoot at f/11-16-22 you will get good deep DoF as any other lens at those f/stops.
In fact these super zooms are better closed down than wide open.

So I reckon you should stick with that lens for 6 months, take lots of different types of photos, learn the art,
then think about more specialised lenses when you really know what you are going to shoot.

Thanks so much Kym...

At least I know that this lens will allow me to learn to shoot different types of exposures and will be a bit versatile. I am going to take your advise and experiment and try to not get to frustrated:) I am not to educated on all of the specs and what exactly they mean re: different lenses.
I guess that will come in time:)

Cheers,
Carrie

Maybe have a look at the New to Photography (http://www.ausphotography.net.au/forum/forumdisplay.php?f=104) forum and the Learning Plan (http://www.ausphotography.net.au/forum/showthread.php?t=24290).

It will cover all your issues.

Look at the Tamron 17-50mm f2.8 when you start doing some indoors
and the Tokina 11-16mm f2.8 if you find a love for landscapes

both are very sharp and quite cheap for the IQ
