Digital Aperture From what I understand on digital cameras the focal lengths are much shorter giving a greater depth of field. Therefore F2.8 on digital gives a f stop equivalent to F18 on 35mm film. This means I cant blur backgrounds. But what F setting should I use for taking scenery shots? if I take a picture on my digital at f2.8 this should give me a reasonably sharp picture since its equivalent to f18 on film, and I used to take scenery on my film camera at f16. Is there any reason why I should not take scenery on f2.8? if I go higher, say to f8 on the digital this would be f52 on a 35mm film. Would this give an exceptionaly sharp pic on this setting? What f stop should I be using? Thanks

Interesting question. I look forward to an expert answering it... I don't fully understand the F-stops, but I do know that I can get blurred backgrounds with my digital camera...

Thanks for the DOf summery Kip. It looks like with digital cameras you do end up using low f/stop numbers. What I would really like to know is what F/stop people who have been using a digital for some time use when taking Landscape. From what I read around about an f4 would be fine. But then what is the point of having the F8??why dont the manufacturers just give you a couple of low numbers. Infact why bother giving you the option to change it at all?? I use a fuji S5500 which is a pseudo SLR. It seems to me pointless having the ability to change F stops when 2.8 will give you the sharp scenery pics and to blur the background I have to switch to Macro Mode. Can anyone enlighten me? Nathan

The range of f-stops allows you at choose an appropriate shutter speed. If you want to show motion with a longer shutter speed, then you need the smaller apertures. Also many macro subjects (flowers, bugs, etc.) need greater depth of field to keep the entire subject in focus.
