buying a lens tonight...which one?

[CanonLaw]

I am trying to decide between the 50 1.4 and the 28 1.8.
I am wondering if anyone has experience with the 28mm for weddings.

I have a 24-85mm USM and a 75-300mm IS right now...so which one of the two lenses would be best for me, the 50 1.4 or 28 1.8? I know the 1.4 is very sharp, but I just don't know how much I would use it with the 10D's crop factor.

Does the 28mm suck as far as image quality goes, or will I still get good pictures with nice OOF backgrounds. Thanks!

[CanonLaw]

oh, I should mention that I am leaning towards the 28mm, because it seems more versatile, but it didn't seem to get great reviews on some sites.

You might also look at the Sigma 30mm f/1.4. I've seen good reviews of that one as well.

According to photozone, it's got edge sharpness issues even on a 1.6x camera. I'd pick something else. Is it mainly the speed that you're looking for or the focal length? Also, do you have a budget in mind?

[CanonLaw]

Ok...
The issue is that I have $325 in gift cards at NewEgg and all they sell is Canon lenses....
So.....I don't have the money to buy this on my own, so I am going to get a Canon lens...

[CanonLaw]

I need the speed and the focal length......I am really wanting the speed, because the 24-85 covers that focal length...but it is to slow!

[CanonLaw]

oh, and the budget is about $430, but I need to buy it from newegg.com

Also, the 24-85 I have right now has edge sharpness issues as well, so the 28 1.8 would be better because it is faster.
I just don't think the 50 1.4 would work well on the 10D for a wedding....

Have only done one wedding with auto focus gear. I borrowed the 28 f/1.8 and loved it. A little soft around the edges wide open. I also had to consider the crop factor of my 20D for use on group shots.

I'd take a look at the 24 f2.8. It appears to perform fairly well wide open. Price should be under $300.

I wouldn't buy an F2.8 prime. My pick is the Sigma 30mm F1.4, which is what i'm going to get for indoors shots. I have the 50mm F1.4 and it's a good lens, not really sharp until F2 but good enough even at F1.4. Or get the 35mm F1.4L ;)

[Rumjungle]

Does the Sigma 30 have problems with border sharpness?
As for the 35L, well, it's truly a benchmark lens...a real performer.

[song4themoon]

I would go with the 50mm 1.4 out of the two that you are looking at

There's a few threads in the lens forum you should read, search will find them.

Why wouldn't you buy a 2.8 prime? What about the 1.8 I mentioned?

[mdm]

I'd get the canon 50mm 1.4 you know it's a L lens in disguise. Just make sure it's wide enough for your needs.

See, I don't know if it is wide enough for my needs.... :( For shame, because it seems to be a nice lens!

There are two reasons to buy a prime: sharpness, and speed (ie large maximum aperture). The only reason to buy an F2.8 prime is cost, because a zoom like the Tamron 28-75 F2.8 is sharp enough and cheap enough.

F1.8 is about a stop and a half faster than F2.8. F1.4 is two stops faster. One extra stop halves your shutter speed. Half a stop would have around half the effect, though I suspect not exactly, because of the way apertures work.

I am selling my 28 1.8 lens with only 100 or so shots on it if you are interested. You can pay with newegg cards, I shop there all the time. I just never use it in the studio.

Do you have a good macro for detail shots? Not familiar with the lenses you currently have.
