sigma 20 1.8 or Canon 50 1.4. which one is faster?

Hi

I am interested in getting a Prime for my D60. Since I am not going to use a tripod for the Prime. I am wondering which one is a faster lens. I do not know much about photography. Please help.

The 20mm, since a shorter shutter speed in needed. Chose the lens for its use however not its hand-holdability.

Those are two different application lenses.

Hello,

I own both. I do not notice much difference in focusing speed. Sometimes Sigma 20 will hunt for 1 second o two. But I don't think it's a fair comparison since they are designed for difference purposes.

Sigma 20 is longer and heavier. Canon 50 is very short but does not have internal focus. Sigma 20 is definitely much louder while focusing though.

Canon 50 is sharper than Sigma 20. But again this is not fair since wide angle lens are harder to make. For both lens you will gain much sharpness if you can step up 1 f stop.

To me the major difference is focal length. You will find situation where you need to go longer/wider. If you don't shoot in low light, then you can consider a zoom lens as well.

Hope this helps.

Now, these two are exactly the primes I own (started with the 28-135, which still is my everyday lens). I got them to fill two totally different needs, and you should consider which one is most like your own photography.

The 50 I bought as a "portrait lens". It equals 80 mm in 35, it is fast, sharp, and gives shallow DOF, exactly what I want. Also, it is a pleasure to use, with full time manual focussing.

The 20 was bought for shooting my grandson while playing in tight quarters indoors. I needed a wider angle (equals 32 mm in 35), and a fast lens. This one does its job, but I would NOT say it´s "a pleasure to use"! To get MF, you must BOTH push the usual switch, AND pull the focussing ring. When buying, I thought this wouldn´t be a big problem, since manually focussing a 20 mm lens on the D60 screen is´nt easy. Problem is, when handlig the lens that focussing ring slips into manual mode all the time, which is not healthy for the focussing mechanism. I HATE that "solution" of the focussing mode switching! Were I to redo this aquisition, I´d go directly for the Canon 20/2.8 instead; it is easily worth one stop to get full time manual.

For this reason alone, I´ll never even LOOK at another Sigma lens!
