SLRs are the only ones that can create this affect to a degree where it is very noticeable.

Wrong. I can set my Olympus C-8080 at F2.4 and it'll create a nice bokeh behind the subject.

As long as you have manual control over the aperture offered, you can get the effect.

Sensor-size plays a big part in visible DoF in digital images.

No, manual control over aperature will not automatically produce that effect.

I have full manual control over my G5, including easy focusing with the function wheel. There is no way I would be able to get the same effect with my camera. I am not saying it isn't totally there (It definitely blurs when I'm up close to the object of course). There will still be a degree of "blur", but it is nothing compared to an slr.

That's because your G5 has a tiny little sensor.

Sensor-size plays a huge part in visible DOF.

Look at the Olympus E-20. You can shot at f2 with hardly any bokeh. You can shoot the same shot at f3.5 or f4 with a 35mm SLR and get the nice creamy more-defined effect.

I know. I was just stating that manual functions does not automatically = mad bokeh. I'll bold to clarify. Sorry for confusion.

can anyone recommend a decent but inexpensive lens that would fit a nikon d50 that has a really low fstop like 1.4 or 2?

also, i think i asked this next question before but i can't find the thread. what about teleconverters? good, bad, useful?

50mm f/1.8 - ~$100

teleconverters are good and useful if you have a high-grade lens. 2x teles lose two f/stops, so if you have a cheap lens like f/6.3, take two stops off of that. Plus AF doesn't work on cheapy lenses with teleconverters.

smaller aperture (larger number) = greater depth of field (more stuff in front of and behind the subject is sin focus)
larger aperture (smaller number) = smaller depth of field

simply set the camera to Aperture Priority, manually set the Aperture to the smallest number, and let it do its thing (autofocus, shutter speeds, and ISO).

I'm still waiting for Nikon to release a full-frame camera. Zeiss is making F-Mount lenses now and I'm excited. Tempted to buy an old FM2N and start looking at the Zeiss F-Mounts...

Don't hold your breath.

The longer it takes Nikon the better. I've spent quite enough on my Contax 35mm setup for the time being.

move the subject to as close as you can focus 🙂
