Sigma 120-300mm f2.8 EX DG HSM

Review Date: Mar 19, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: Very Sharp, cheap, build quality, works great with TCs
Cons:
Even not slow, AF is not as fast as expected.

I must give a full 10 on this lens, if only for the price paid. This lens is trully one of a kind. Where else can you find a zoom lens reaching up to 300mm with a constant f/2.8? And keeping its sharpness throughout its range too.

This lens is SHARP. I mean I was looking at photos I took the first day I bought it and i was double checking if the photo was indeed at f/2.8. At f/2.8 this lens is very sharp. If you step down at f/3.5 it looks like it's been sharpened in photoshop.

As I wrote above, I was expecting faster AF. Don't get me wrong, the AF is fast, but not lightning fast as expected from a professional lens like this. I don't find this as a limiting factor. I mainly do wildlife and it's great for birds in flight. I am not sure how it would handle in a F1 track though, even though it would be more than adequate for all other motorsports.

Some people state the lack of IS (or OS in Sigma's case) as a con for this lens. Why is that? You are buying a lens without stabilisation, why cry over it. If you want stabilisation, pay twice as that and get the Canon prime. For God's sake, this is a bargain.

Again, some say that it costs money to buy filters for this lens. I agree here, it would be better if you could use drop in filters like the 300mm prime but people that say that it costs to buy the UV for protection I just laugh. I myself paid $200 for a Heliopan UV just to protect this baby and not degrade its quality. Again, the filter size is part of its specifications and it's even quite small for a 300mm f/2.8

Even Sigma says that this is sharper than its 300mm prime. I've read reviews that the Canon is sharper than this. To be honest, I can't see how it can get sharper than this, and if it can, then good for those who can afford it, I can't!

Pros: SHARP, price, build quality
Cons:
A little flare prone, you should always the lens hood.

This is an amazing lens. About 80% of the photos I have in my "keepers" folder came from this lens. It actually boosted my photography to a new level. It brings out your creativity, with beautiful distortions, even though distortion is not the correct word, the lens is actually distortion free, but the extreme wide angle effect is something that the human eye is not used to, which brings this wow-effect to your photos (by wow I don't mean world of warcraft).

This lens is as solid as lenses get. By the first time you hold it you think, this is a quality lens. I've owned it for almost a year now and it has produced great results. I have actually produced A0 prints with this lens, and the results where amazing!

I might have got a good sample of this lens but I can hardly find any cons for this lens, besides the obvious difficulties with extreme wide angles, like vignetting when using thick filters, difficulty when using Cokin or Lee adaptors, and the occasional photo when you have accidentally put your feet in the frame.

Pros: Price, sharpness, weight
Cons:
none for this price

Nothing more to say actually. Buy this lens, you'll be amazed what an aperture of 1.8 can give you, and check out that price. It's amazing.

Probably one of the sharpest lenses I have ever used!
