Sigma 300-600mm F4 DG OS Sports with the CamDec Lens Cap
Sigma recently achieved what many thought was impossible by releasing a constant f/4 aperture 300-600mm lens, the Sigma 300-600mm f4 DG OS Sports . This lens is a genuine powerhouse for Sony E and Leica L mount users. It is such a massive piece of glass that it currently holds the record for the largest front opening of any lens on the market. I know this better than anyone because I reviewed the unit and ended up designing a custom lens cap just to ensure it had a perfect fit.

The most impressive part of this release is the value proposition. Even at its standard price, it offers professional-grade super-telephoto performance for a fraction of the cost of its rivals.

Unbeatable Value vs. The Competition
When you compare this to the 600mm f/4 primes from Canon, Nikon, or Sony, the Sigma is a total steal. Those lenses often retail for double the price of this zoom.

The 1200mm Secret for Sony Users
While Sony teleconverters on E-mount cameras originally did not support this lens, we received a workaround recently. The Viltrox 2.0x Teleconverter is fully compatible with this lens on E-mount cameras. If you need extreme reach, this combination effectively turns your setup into a 600-1200mm f/8 lens. It is the perfect solution for photographers who need the absolute maximum zoom range without spending five figures.

I have been shooting birds and wildlife in North Carolina since 2014, mostly with Sony bodies and long telephoto glass. I built and maintain the Camera Decision database, so the specs and comparisons here come from data I curate myself rather than copied press releases.
