Sigma 300f2.8 Prime or Sigma 120-300 f2.8 Zoom

ANGUS · 8th of April 2008 (Tue)

They seem to be very similar price i was just wondering if the prime focuses faster or is sharper?

Thanks.

frici · 8th of April 2008 (Tue)

the Canon 300 2.8 has much better image quality.

ANGUS · 8th of April 2008 (Tue)

At a much higher price out of my price range.

The 120-300 is better.

More useful having a zoom. The typical drawback of a zoom against a prime is the sharpness, but I've seen comparisons between the Sigma 300mm and the 120-300, and ironically the 120-300 came out better.

Lots of examples on last page

Thanks for that, Very surprising! Also anyone used the Tokina or Tamron (Cant remember who had one) 300 f2.8?

way to go at answering the question he asked

Everyone (I know of) says the 120-300 is sharper than their own 300.

120-300... awesome lens but heavy

Cadwell · 8th of April 2008 (Tue)

Amusingly enough Sigma managed to more or less kill off sales of their own 300mm f/2.8 prime when they released the 120-300mm f/2.8 zoom... Perhaps that's why Canon won't release any wide aperture telephoto zooms? Anyway, I digress. The 120-300mm is the better buy of the two.

Oh Lord... I hear this all the time. Within a few grams it weighs the same as the Canon 300mm f/2.8 so it weighs pretty much what it should weigh as a 300/2.8 lens. In fact if you follow the "wisdom" regarding zooms versus primes spouted by the armchair experts on this forum it should be a lot heavier...

A 300/2.8 needs a lot of glass and glass is heavy...

bobbyz · 8th of April 2008 (Tue)

I agree, heavy is all relative. Once you hand hold 500mm f4, 300mm f2.8 is nothing. Most people using 120-300mm f2.8 or the 300mm f2.8 for sports are using monopods.

sorry, I misunderstood, I thought you ask Canon 300 2.8 or Sigma 120-300 2.8. That is a different question.
I heard very different opinion about 120-300 quality, and that is a little annoyance.
