    Hello. I am new to this forum, I am from a video shooting background and I a m going in to photography as well. I used a lot of 35mm lenses, using lens adapters on my video camera. 35mm lenses are used there to get very shallow depth of field, because of the image sensor in camera as it is not 35mm format. The question is, what will I get if I put my 35mm nikkor lenses on a non full frame camera? I know that cropping will happen but will it produce the same shallow depth of field?

    I am looking to buy a good Nikon DSLR as I allready have a lot of Nikon lenses, price range not above 2.5K $. Any recommendations?

    Thanks a lot

    The d300.

    The D700 and D3 are better, but you'll pay for the quality.

    All your lenses will be 1.5x as long as they were on your 35mm. So a 200 becomes a 300, a 50 becomes 75 and so on. The depth of field will not be quite as shallow b/c the crop is taken out of the center, sharpest part of the lens. The D700, which is on sale right now at B&H for $2700, would give you the shallow depth of field you are used to.

    The lens controls the DoF. I get plenty of shallow DoF shots with my D300.

    DOF of a lens at a given focal length doesn't change regardless of what you attach it to.

    In fact, if you want to get into "perceived focal length" due to the reduced sensor size, it could be said that there is a wider dof on a crop sensor or smaller film then on full frame, because a 200mm f2.8 creates a more narrow dof then 133mm f2.8; yet 133mm x 1.5 = 200mm.

    No, read djacobox's comment. The type of sensor affects what part of the image you capture from the 200mm lens. The 200mm's lens DoF stays the same. Only if you consider the 200mm as a 300mm lens, rather than a 200mm with a 1.5x cropped factor do you start to think that the sensor affects the depth of field.

    Will the sensor size affect the circle of confusion?

    The sensor does indirectly affect the DOF. This is due to the fact that the cropped sensor pushes you back when you frame your subject.

    If, on a 35mm sensor, you needed to be 1m from your subject, now, to compose the same shot, you need to be ~1.5m away. And since DOF increases as the distance from the camera to the subject grows, you just lost the hair-thin DOF you bought that 85 f1.2 L for.

    False...

    Why do you guys think that large format shooters use f/64? And a really shallow DOF is almost an impossibility with a PnS? Sure you can get a little bit of blurry background on a flower macro but you know what I mean...
