I really don't care, I will use whatever aperture I have to so I get the image I want. I have taken portraits at f/0.95 to f/64 - there isn't any hard-and-fast rule about aperture/subject relationships.

There is a rough division: Thin DOF is for art. Thick DOF is for sales
interesting way of seeing things.

Shocked and a bit saddened...

I'm a bit shocked and saddened that no one has recommended the following book:

Amazon.com: Understanding Exposure, 3rd Edition: How to Shoot Great Photographs with Any Camera (9780817439392): Bryan Peterson: Books

It makes me think that not many people here, or on this thread at least, have read it.

Peterson gives a great discussion about aperture and selecting the best aperture for the kind of exposure/print/shot you're attempting. Invaluable resource! Shame on all y'all for not suggesting it. Of course I'm kidding, a bit, about the shame part. I really was surprised no one recommended this essential book.

The answer "I go by feel" isn't much of an answer at all, particularly when answering a novice's question. Read this book: Thank me later.

Hello Pentaxians, did we forget that every lens has its best Aperture setting. And I think some DSLRs allow you to set your camera for this - is it called MTF or something? At this aperture or a an aperture range, the lens gives its best shot.
A Google search might help bring out this concept.
Enjoy your lens.

We didn't forget - I mentioned this idea in my reply - but it's way less important in most situations than choosing the DOF you want or getting the shutter speed you need.

Hello Marc, you are my hero on this and some other forums too. I value and read all your photographic articles and contributions. Please accept my humble compliments.
You might have read this one about the DA 18-55 ALII Kit vs the DA* 16-50 f2.8:- The surprise is that at smaller apertures like f8 to f16 the kit lens comes pretty damn close to the DA* 16-50 in terms of sharpness. In fact the 18-55 AL II was noticeably sharper than the 16-50 at 28mm. Set to 18mm at f4.0 the DA* 16-50 clearly beats the kit lens.

Wow, that's some compliment - thanks!

I don't think I saw the test you refer to, but it doesn't surprise me - the 18-55 is better than most people give it credit for, particularly at the middle of its range and stopped down (eg, typical landscape use).

I managed to get a Highly Commended Art ribbon with the 18-55 kit lens, it certainly is under-rated.

Thanks for the tip about the aperture sizes working best with certain lens, will have to google.

I have read understanding exposure and it was very helpful. I just felt I was over-using certain apertures lol

There are a number of review sites where you can find decent information about lenses (only the ones they have tested of course) - dpreview.com is one, lenstip.com is another and I am sure there are more. dpreview.com happens to have a rather nice (IMHO) interactive presentation.
