OK, several mates weddings coming up and wondering whether a Canon 50mm f1.8 would give a better image (sharpness at large aperture, bokeh etc...) in low light compared with my current Sigma 18-50 f2.8...

Any one happen to have experience of the two lenses??!

Random friday night musings ๐Ÿ™‚

The fifty is a top lens for the money, definitely worth a punt.

the sharpness of the canon 50mm is amazing to me as a photo novice, but I find that the autofocus accuracy (esp when stopped right down and the depth of field is about as far as I can throw vanessa feltz) can be a bit out sometimes.

50mm not going to be great for weddings if you want to take those big line-up shots.

But great for portraits at the night do.

I'll hazard a guess that the 50mm is quarter of the weight and also the price?

Obviouslly it won't do much in the way of wide shot, especially on a crop frame sensor, but year should make a half decent portrait lens. I also guess that the sigma isn't 2.8 all the way to 50mm so will struggle to shoot with a small DOF.

Yep, it's the low light night and indoor portraits I'm thinking. The 18-50 will get used as it's a mighty fine lens. just wondering if at the 50mm end the 50mm fixed would be noticeably better.

Might just take a punt ๐Ÿ™‚

50mm pin sharp and will be great for portraits, low light focusing might be a problem though.

The new Sigma 17-50 OS is supposed to be very good, constant f2.8 and stabilised too
Flog your current lens and buy that instead of the 50mm, best of both worlds then.

If you are getting paid for the weddings treat yourself to the Canon 17-55mm and 70-200mm.

Not getting paid - just favours for them all really. The sigma is a very good lens- it's 2.8 end to end, very well made and pretty heavy. It's going on a 10d, so already reasonably heavy! Will look into that 17-50, ta for the heads up.

Potential also for a 28 or 30 prime. Saw the results of a 35 I think it was on a mates nikon d90 and was impressed!!!

Oh, and I'm not the sole photographer, my main aim is evening relaxed & casual shots. Someone else (paid) is doing the formal stuff.

I've got a 28mm f2.8 which was used on a 10d and now on a 20d. A much nicer lens than the 50mm, I sold the 50mm and kept the 28mm, for portraits you might want to look at the [url= http://www.the-digital-picture.com/reviews/canon-ef-85mm-f-1.8-usm-lens-review.aspx ]85mm f1.8[/url] which will work perfectly for portraits, give beautiful colour, spectacular bokeh. This would be much better than the 28mm as you'll need to be in the subject's face with the 28mm, too intrusive to get any good candid shots. I can't recommend the 85mm enough, go for this over the 50mm. You can always sell it after if you don't get on with it, but trust me... ๐Ÿ˜‰

I should have said- I also have a canon 100mm f2 which although a little on the long side, still does a great job of portraits.

I did the same thing. Gave the couple a few copies of the photos in photo books.

I used a FF camera and 50mm f1.4 and 135mm f2.8 and didn't use a flash (too intrusive). I'd use that combination again. I was using f1.4 & iso 1600-6400 a lot in the evening. The 2.8 would have been a bit slow but more importantly too long.

Another plus of small primes is you look less of a loon. ๐Ÿ˜‰

Personally I'd be looking at a fast 28-35mm prime to go with your zoom. I think I'd find a 50mm too long. Or... ditch the zoom and take 28mm & 50mm primes.

28 and 50 primes are what I'm thinking at the mo!
