    This is a semipopular question, the results you are going to get are likely going to lean toward get it or get the 1.8 if money is an issue.

    50mm primes are prolly one of the most versital focal length lenses offered. Even if you don't currently use that particular focal length with much frequency, there will likely come a time when you find it to be a part of your everyday equipment.

    Yes... I agree... but on a crop body some find the 35mm lens more useful. Street shooters often will go even slightly wider.

    yeah, my camera has a 1.5 crop factor.

    what i'm asking really is would the 20mm prime produce significantly sharper pictures than my 18-200vr? since i almost always use that lens at between 18-24mm, i think that 20mm would work good for me. i don't want to buy an almost 500 dollar lens for not much difference results, you know?

    Well, both the 50mm and the 20mm produce some very sharp results, and both would almost certainly be much better than your current lenses (primes are always sharper than zooms). However, whether you'd actually find more use in the 20mm is really up to you. Do you do street photography, landscape or portaits? Because as wide a lens as 20mm would probably only be useful for landscape.

    To be honest, I would recommend the 50mm f.1.4, simply because it's the right balance of price, zoom level, and aperture.

    Bear in mind, however, that you will not be able to autofocus on any of those lenses with your D40x. All other modes, like metering, will be avaliable, just not autofocus. If you really want autofocus, then I would highly recommend the Sigma 30mm f/1.4 HSM. It's more expensive, but if you're willing to pay...

    For less than that, I would suggest that you look at the Sigma 30mm F/1.4 lens.

    It is right in the range you are looking for and a much faster lens.

    I just recently pulled it out to save me during an indoor (inside a house) shoot where I was asked not to use the flash. It worked great!

    I dont know about the 20mm. But my 50mm 1.8 produces MUCH sharper images than my 18-200VR did so my guess is yes.

    In fact I wasnt happy with th 18-200 sharpness at all, so i sold it.

    hmm well i think the 18-200 takes somewhat sharp pictures so if the 50mm is as good as you say i should be pretty happy.

    i think i'm actually gonna go with the 50mm 1.4, since it's the cheapest of the 20mm and the 30mm sigma. plus it will force me to use a different approach to taking pictures since it isn't wide like i typically use.

    b&h and adorama both don't have it in stock though :/

    Lack of sharpness for me is not an issue with the 18-200... it is a pretty slow lens, though, and is best used in brighter situations, but its a wonderfully versatile lens.

    They have the 50mm 1.8 in stock. Is there a particular reason you want the 1.4?

    The 1.4 from what I understand is built alot better than the 1.8 (plastic) but for the money I think you cant go wrong with the 1.8

    From what I believe the only differences is obviously the 1.4 and the build - image quality / sharpness is much on par? I dont know, I have only ever played with the 1.8 version.

    I used to think the 18-200 was great until i started playing with primes and the 70-200. Just doesnt compete at all - except for versatility.

    the main reason i want the 1.4 is because i've heard a lot of good things about it, such as it has superior build quality to the 1.8 which is pretty important to me. also i like the 1.4 aperture. not that i have heard anything bad about the 1.8 though, i just want to go with the 1.4. and it'll probably be 2 weeks or so till i have the money for it, so hopefully b&h or adorama will have it in stock by then
