Luminous Landscape posted their full Sony 12-24mm lens review

The 12-24 Sony lens is not a G-Master, but it should be.  It passed with flying colors for the kind of work I do.  It makes shooting wide-angle fun.  I often find myself taking this lens out of the bag and just having fun with it. I have complete confidence that it will give me sharp images with good contrast and no more distortion than expected. And, I know I can use Capture One to correct for some distortion, especially keystoning.
If you have a Sony system or are thinking of getting one, make sure this lens is in your kit. The price is more than fair when compared to Nikon and Canon. The weight will make using this lens a joy. I tip my hat to Sony for making such an incredible lens that I know many shooters will thoroughly enjoy.

Imaging Resource posted their 100-400mm GM field test. And their conclusion is that this is a “A home run for Sony E-mount owners“:

What I like:

• Great build quality
• Excellent image quality
• Good control of chromatic aberration
• Versatile zoom range – and a really nice zoom mechanism
• Impressive close focus capabilities
• Despite being expensive, this is a great value given its unique role in the E-mount lineup

What I didn’t like:

• Quite front-heavy with the APS-C A6500 body
• Autofocus can be slow when focusing on a close subject, especially at the telephoto end
• Focus ring feels loose
• Not easy to remove the tripod foot

While the performance of a zoom lens won’t match a similar prime lens, all else equal, the Sony 100-400mm G Master lens is still incredibly sharp and performs very well. Considering its versatility, build quality, optical quality and price, the Sony 100-400mm GM is a home run and deserves a place in the kit of every Sony E mount shooter in need of telephoto reach. Granted, it is still $2,500 and that is a lot of money, but if you can afford this lens, buy it.
