Adv of 2.8 lens goes away on Digital SLR??

Also the advantage with a fast lens of less depth of field and better autofocus in low light. Those two things don't change regardless of what the lens is attached to.

The advantage with a slow lens on a DSLR is that you can bump the ISO up a stop or two for a shot if needed. Of course with film, you'd have to put in another roll which you might not do for just a quick shot. But to say that the advantage of a faster lens goes away just because it's on a DSLR is incorrect.

Hello,
I am sure you are right about depth of field. However my primary concern was quality of picture. I am an armature. So unless there is a difference in quality of images which is noticeable, it would be hard for me to justify spending $1500 on the lens. Unlike professional I will not be putting the lens through rough time. And the DOF will not matter to me too much is quality of image is almost as good as the pro 2.8 lens.

However if I make a 9' by 8' print from these lens and there is a noticeable difference in quality then of course I will go for the pro lens.


Thanks for you comments

Is that a print size of nine feet by eight feet? If that's the case then one of the camera maker's sharpest lens (probably a prime lens) will be in order. Of course a tripod, cable release and proper shooting technique are also a must.

If you meant inches, then I think you'll be happy with most consumer zoom lenses - especially the one you mention. I've taken a few shots with that lens and been impressed by the quality versus the size and weight of the lens. It also focuses pretty close for a 300mm lens. IMO, lens sharpness really can't be discussed unless we're talking about shooting on a tripod, etc. anyway...

Hello,
I meant inches.

I guess I am leaning towards the Nikon 70-300 ED. I called up the camera store and they told me that I can try out both the lens. So to be 100% sure I will go and try out both the lens and make prints out of the pictures I take.

Thanks
