New 50/1.4 with D Rebel

[s_hassan]

I just got the 50/1.4 for my 300D and took some pictures. I find a

very significant darkness in the corners especially at 1.4. It

doesnt disappear till I go down to 4.0

Well I dont know what will be the benefit of buying a fast lens if I

cant use it without having an aperture larger than 4.0 in lowlight

without getting the dark corners. Does that defeat the purpose of

having a large apperture.

 

Is it normal for this lens. I read in the reviews it happens with

50/1.8 and even that is not so obvious on digital due to 1.6

cropping factor, but for 50/1.4 despite cropping factor......

 

Is it some fault with this particular copy of the lens? Should I

return this lens to B&H? But then I wont get my tripple rebate on D

Rebel as 1/31/05 is the last day to purchase any items for that

 

Help please<div></div>

Try one w/out the flash ? evenly lit blue sky. What?s the benefit of buying a fast lens if you?re gonna use flash?

If you find a 50/f1.4 that has no vignetting wide open, you might want to alert physicists about your magical lens. As long as your stuck with the laws of physics that apply to this part of the universe, you might try taking some photos where the falloff isn't so noticeable or objectionable.<P>

this is one outdoor. You can see some darkness at the corners. Aperture again is 1.4.<div></div>

Minor vignetting isn't really a problem unless it detracts from a photo that's actually worth looking at. People seldom care whether test images of blank walls or empty skies have perfectly even exposure across the frame.

The point of shooting at f1.4 is to get a particular expression, gesture, atmosphere, etc... that you couldn't get otherwise. Vignetting doesn't detract from those. It's pointless to try to produce a technically perfect (or even good) image at f1.4. Besides vignetting, sharpess and contrast are just dismal compared to what the same lens can do at f5.6.

There's nothing wrong with your lens based on that photo. That's really minor vignettin -- and totally negligible for f/1.4. As others have said, you won't be shooting at 1.4 outdoors under cloudless skies.

<p>I use my 50/1.4 on a film body. At f/1.4, there is vignetting in the corners; that, as others have said, is a fact of life (actually, a law of physics). It's gone well before f/4, though, and I'm surprised that you are seeing a lot of it on a 1.6 crop body.</p>

Hi,

 

What I see in the first photo might be due to the flash. Anyhow I use film, and I do not see such a vignettering even at f1.4 . So with a crop factor of 1.6 I would not expect to see any problem.

 

Regards,

 

Olivier.

Here is a shot of a Kodak grey card taken with the 50mm F/1.4 at F/1.4 with a 10D and then given a storng dosage of radial blurring. I use this and similar images in Photoshop to correct for vignetting by layering it over the image, inverting it, and using a blending mode appropriate for the image, usually vivid light.<div></div>

I'm convinced that the problem you are having is being caused or at least exacerbated by underexposing. Try setting your camera to +1 and see if the problem eases up. Cheers.
