Sigma Launches the 120-300mm F2.8 DG OS HSM

<< < (2/10) > >>

I really hope this lens brings good quality, at least comparable to the Canon EF 300mm f/4 L IS or 400mm f/5.6 L and gets well along with the Teleconverters. I had the Sigma 120-400mm that I know it's lower on the line but ir was awful when compared to any canon zoom.

For thePrice this Sigma 120-300 2.8, will hardly match the new Canon EF 300mm f2.8 L Mk II

Obviously we're not seeing any tests with this lens yet, but if it performs well with a 1.4x TC I could see this standing in as my poor-man's 200-400mm-ish (168-420mm FF) type of lens for some of that distant action and animal stuff that I.... never do :)

Anyway - I MIGHT do more of that, and with the Canon 200-400 rumored around 11k I can only hope for the Sigma to deliver decent quality and sharpness - even with a 1.4TC. (The point being that I often work in environments where trying to change lenses is not just a hassle but close to stupid, and so with a Canon 70-200 2.8 IS II and this Sigma on two FF bodies I could cover a good range of distant subjects with very little focal distance overlap).

But... yeah well. Let's see about that once we get some tests (now get us some tests, already!).

:)

Beside a new cosmetic treatment, it's the exact same 120-300 launched in 2011, no mechanic or optic change ;)

But a very good lens, very sharp ! only con, pretty heavy...

Lee Jay:
I'd really like to see some tests with teleconverters on a high-pixel-density 1.6-crop sensor.

Except that the 200-400 comes with a 1.4X TC, making it a 280-560. To do that with the 120-300 would require a 2X TC. Based on my experience and observations, the resulting images would not be acceptable. Sigma needs to scale up the 120-300 design into a 200-500 f/4. Their 200-500 f/2.8 is an overweight, overly expensive joke.
