Has anyone tried both of these?
I have the 1.8 and would like to upgrade to the 1.4. Both of them are cheap, but is there a good reason to upgrade?
My 1.8 is great but it often exaggerates reddish colors. But maybe that̢۪s only my version. Here̢۪s one example:

the 1.4 has slightly more attractive bokeh. The 1.8 tends to produce pentagons in oof regions because it has fewer aperture blades than the 1.4.
The 1.4 is faster - both aperture and focus speed, though the 1.8 isn't exactly slow.
1.4 is a bit bigger, so balances out a 1DII better.
Better construction, maybe better colour. Not really much sharper, given that the 50 1.8 is so sharp already.
I recently upgraded to the 1.4, because I wanted a slightly faster lens with better construction and a quieter motor. Doesn't harm things that it is sharper stopped down than the 1.8 as well, for the same f-stop.
The 1.8 certainly holds its value well though, I sold it for $5 less than I bought it for :)

| I find the colors very good on my 1.8, and since it was about one sixth the price of the 1.4, I see no upgrades in that area for me. If money is no object, I would reccomend the 50mm 1.0, at a mere $4200. even nicer than the 1.4. |

If you buy one, you get what you paid for. If you buy the other, you get MORE than what you paid for it.

I recently took a LOT of pictures with my 50mm f/1.4 - it's an awesome lens - and SHARP. The following pics both only had 85% USM applied to the whole picture (no extra sharpening of the eyes or anything else). The 1.4 is an awesome available light lens. [you can find more examples in the FACES portfolio in my profile]

f/1.4 vs f/1.8 at Petteri Sulonen's Prime Junta site.
Also check out the other stuff on his site.

Another numeracy point - but f/1.4 is actually a hell of a lot brighter than f/1.8
Roughly speaking, the 1.8 allows 55% of available light through to the sensor, when wide open. The 1.4 allows roughly 72% through. In terms of sheer quantity of light, it's the same difference between a f/4 and an f/2 lens.
I use the 30mm f/1.4 a lot indoors - even in gloomily lit pubs it can get decent reults with no flash. Which i like because I hate flash :-)

| I've been using a Sigma 30mm f/1.4 on my 10D, and it's fantastic. It balances out a full-sized body very well, too. (It's a fat hunk-o-lens.) |

I just made the switch to the 1.4, and it's AMAZING! the difference in 1.4 and 1.8 is HUGE when you're talking about light... I'd post some shots, but I don't want to comprimise the challenge entry I have in right now... And my 1.4 is much sharper at 1.8 than the 1.8 is. (edit: it's sharper at all aps, actually...)
As far as value goes, you probably get the better bang for your buck with the 1.8... That being said, I wouldn't give up my 1.4 for anything...

| The one thing I will say about the 1.8 in the negative...after you get used to USM, it is SLOW to focus. It also sounds as loud as a bullhorn. |

One thing I don't like about the 1.8 is the lack of hyperfocal markings. Though, I think for the money it's a tuff one to beat.
