Lenstip and L-Mount

[SimonC]

I've just noticed that Lenstip.com have started testing L-mount lenses. The first one tested is the Panasonic S Pro 50mm F1.4.

That's good to hear. Lenstip can be pretty acerbic, but their testing is pretty extensive and technical so I trust them.

The issue is they only test one sample each time (like many reviewers).

By example I had two copies of the Sigma 28-45mm DG DN, neither copies were similar to the test of Lenstip. By exemple at 45mm my second copy is much sharper than on the Lenstip Sample, it's not even close, it's even sharper at 45mm than at 28mm, and very close to the sharpness at 35mm.

I can see the same with the 50mm S Pro, my current sample is much sharper wide open than on their test, sharper than my Nikon 50mm Z f1.2 at f1.4 and my Nikon 50mm Z f1.8 wide open.
I know there are lot of "so so" copies of the 50mm S Pro as I owned one slightly soft wide open. But a good sample of the 50mm S Pro is much sharper than on their review.

My 35mm GM is also very similar to my 50mm S Pro wide open and slightly sharper than my Nikon 50mm f1.8 Z, so yes they make good tests, but sample variation is a real thing and it's hard to really test a lens sharpness with only one copy, especially when lenses are subject to sample variation like the S Pro line.
