28-70 2.8 l

[PAR]

I have read a ton about Lenses on this board. After all that I have read - I purchased a 28-70 2.8L for my wife. We are still waiting for the D60 to arrive but decided to put the new lens on her EOS 630 and compare simalar shots (indoor and out) with her old 28-80 usm. Got the pictures tonight and although nothing really sticks out the L lens seems have a little better detail.

Can anyone tell me if this difference will be more pronounced on the D60 or similar to the film and Eos 630 ?

Thanks

Paul

Are you comparing 8x10's or tiny pictures. Take the shots with the lens wide open and print at 8x10. Now you will have a difference. With the D60 you will work with much larger images, that's where the 28-70 will stand out.

What size were these pictures? Are you talking about snapshot 4x6 prints or 8x10?

In addition to a 10%(subjective) increase in sharpness, I find I get better focus accuracy with the 28-70L. For example, instead of 30% out of focus shots, I might only get 10% out of focus. Also, the larger apeture will enable you to get shots that you wouldn't be able to get with a slower lens.

Additionally, with the 6 mp sensor on the D60, I find that I can crop my images and still get a high quality picture. A better lens give you a better original to crop from.

They were 4X6 - I was going to do the 8X10 comparison bet my wallet said no. I will keep the 28-70 L. Just wish my D60 would get here.

If I am not a "pro" how do I know I got a good 28-70 2.8 L ?

Here's a simple test I use, I don't know if it's scientific or anything, but it satisfies me.

Take three pages of USA today. Tape them together on a wall. Take a few photos at 28mm. (slightly move the manual focus ring after each picture so the camera will need to refocus) Move your tripod back a few steps back, take a few pictures at 50mm. Take a few more steps back an take more at 70mm. In each of the photos the newspaper should be the same size. Be sure and use the same aperture for all the pictures.

Then compare the images (they should be very close) and post them here for others to view.

For testing sharpness I shoot at a screen... the one on my front door. I put the camera on a tripod and shoot at various apertures (and if a zoom lens, at different focal lengths.) At medium aperture (f8) and medium length (50mm), you won't see much difference. Wide open at 28mm and 70mm you'll see a difference in the edges. The center should be pretty sharp throughout on both lenses.

Note: Never use prints to judge a lens. Slides viewed with a good loupe tell the story.

Thanks - what do you think are my chances of getting a dud ? I purchased online from deltainternational.

Paul,

If you can already tell the difference with casual observation of 4x6 prints, anything larger will really emphasize it. When you're looking at 4x6 prints, you are looking at small enlargement, with a 2nd generation of distortion, and that's assuming the minilab printer is in perfect condition. This will mask many image imperfections simply due to the imperfections of the process.

Opening a D60 digital image on your computer screen, on the other hand, is like looking at a slide through a 30x loupe, even without going beyond 100% pixel level. This is what gives so many D60 owners L-disease. You don't have to try hard to see every little detail (and thus every little flaw) of a first-generation image. Instead of peering at a light table with a loupe, getting watery eyes, you have an easily scrollable version, bigger than life.

In addition to a 10%(subjective) increase in sharpness, I find I
get better focus accuracy with the 28-70L. For example, instead of
30% out of focus shots, I might only get 10% out of focus. Also,
the larger apeture will enable you to get shots that you wouldn't
be able to get with a slower lens.

Additionally, with the 6 mp sensor on the D60, I find that I can
crop my images and still get a high quality picture. A better lens
give you a better original to crop from.
