    Nikon 50mm f1.4 or 1.8?

    So I have been toying with this choice for a long time. Actually just wondering when to get the 50mm 1.8.
    I have the 35mm which is too short for a portrait lens really, and the 85mm f1.8 too expensive.

    therefore, I want a 50mm. However, what is the difference in DOF from 1.4 to 1.8? There must be a reason why people buy the 1.4 over the 1.8? From what I have seen its not amazingly better optically, but is slightly faster.

    Like I said i am more concerned from a DOF point of view, wide open. Anyone help?

    Thanks

    It's not slightly faster. F/1.8 to F/1.4 is almost one full stop.
    F/1.8 offers value for money but F/1.4 offers brightness. Optically, I don't know crapz between the 2.

    thanks tim11. You are right, it is fairly fast. But its the shallow DOF you get with the 1.4 what I am wondering about. My brother has the canon 5D and a 50mm f1.4. That has almost impossible DOF wide open. But then its better on a full frame camera!

    I bought the 50 1.4 not because it was a full stop faster but because I was very sure it would be a tad bit sharper at 1.8. Years ago I started with a canon 1.8 then bought the 50 1.4 and found it focused faster, more accurately, and was sharper than the 50 1.8 vesion @ 1.8. However, when I switched to Nikon I passed on the 1.8 and when I my Nikon 50 1.4 arrived it shocked me wide open:



    I included this larger size because I think it shows you just how exceptable it is wide open. So, if money is no option I'd get the 50 1.4, but the 50 1.8 is no slouch either. I prefer the 50 1.4s at 1.8 to the 50 1.8s wide open - that was my basis.

    whoa. That really shows off the lens. Is that straight out of the camera? has good contrast and sharpness.

    I love the DOF on that lens...!

    Hey I know this if an off topic question, but if I decide to get the D80/D50 Nikon body, will my D40 lens work with it? I was just curious.

    will your D40 lens work on the D80/50? Yes, any lens that works on your D40 will work on those cameras.

    Thanks for the quick reply, herc182!

    The reason I ask is because I bought the Sigma 30mm f1.4, but also considering of getting the Nikkor 50mm f1.4. I noticed that it's not HSM so it will not autofocus on my D40 therefore I could get a nicely used D80/D50 body and still be able to use my other lenses working on my D40

    The difference between the D80 and D40 (with respect to lenses) is that the D80 has a builtin AF motor. Therefore it will focus the lens itself when you press the shutter button. The D40/x doesnt have this and you have to MANUALLY focus the lens.

    I think the D50 also has this motor so the lenses will focus automatically.

    I've had the 1.8 and 1.4, and while most technical reviews say they are very similar optically, I always felt the 1.4 was sharper and had better contrast.
