F1.4 to 1.8 is certainly going to be better than F2.8.

Based on what I have read in various forums I would just go with the 50mm 1.7

The 1.4 is better but I'm not sure it will be that much better to justify the difference in price. Part of the difference in price is the fact that the 1.4 is muchrarer than the 1.7. If you are using it professionally, the price might be irrelevant and I suppose it might get you a few shots the 1.7 can't.Someone who actually has both might be able to give you more insight as to whether or not it is worth it.

I have the new 50mm f1.7 too, but there were about 20% of the pictures I took yesterday out of focus, do you have this problem as well? I used auto focus.

f1.4 is only 1/2 stop brighter than f1.7, I don't personally think that's worth the price difference between the lenses. (the f1.4 50mm is approx 2.5 times the price of the f1.7 50mm) It does depend on how often you'll be using it in low light , sometimes 1/2 stop would be nice. I'd personally keep the ~$100 difference and put it towards another lens.

I've seen those 50mm lenses (both varieties) at KEH, Adorama and B&H at times. They're a bit more expensive than Ebay but you do get a bit of extra security when buying from a dealer. I'd expect to pay just under $100 for a 50mm f1.7 and just over $200 for a f1.4

I have the 1.4, because I found a real deal on it used, but if I was buying now, I would get the 1.7. The 1.7 focuses twice as fast as the 1.4, and costs much less. j.d.katz on eBay isn't always the cheapest, but I have bought a lot from him, and from personal experience, he stands behind his gear when it turns out to be defective.

I've used the same Ebay seller on several occasions and find him honest, quick to ship and conservative on ratings. His prices are a bit higher but worth it IMO.

I would buy a 50mm f1.4 if I found an outstanding deal, but unless I found that I needed the extra aperture speed I wouldn't pay todays premium for one.

I think I'd buy a Sigma 28 or 30mm f1.8 before I bought another 50mm for 1/2 stop of light. (though that would cost quite a bit more than the 50mm f1.4

I agree... I was going to suggest something wider like the Sigma.

well i had two models of the 20mm sigma f1.8 from BH but both didnt work on my 5D or 5, so im stickin to minolta.

thanks for the tips, i thought the 1.4 was a lot more brighter than just a 1/2 stop!!!

The difference is less that 1/2 stop than the performance at f/1.7-f/2

I upgraded from the 50/1.7 to a Sony f/1.4 and like it a lot. By f/2.8 they are probably about the same, aside from coatings and ADI.
