Couldn't you have chosen a better scene? Perhaps a landscape/portrait where
extra detail can be more easily compared between the photos. Let's be honest,
who's ever gonna take a photo with these lenses on a doll. For crying out
loud, get some models and I guarantee this will take off! 2. would like to see
more lenses to be added, along with different zoom settings

I'm no lens expert but I'd imagine that the differences in lighting and motion
in landscapes and portraiture between takes might obscure the subtle
differences between the lenses themselves. The static subjects probably give a
more fair comparison.

Difference lenses have very different MTF (resolution vs how far away to the
center of the lens) in theory and because of the different lens internal
structure, they also have different fringing, distortion performances as well.
The bokeh look different depending on the shape and the number of aperture
blades. Sometimes it is not clear whether spending 2x or more is worth it so
this is I believe very helpful to help buyers to see what's the actual
differences of lenses are without all those fancy ads.

That's very, very nice! Thank you!

I noticed that on the most expensive lens, in the "car" scene, the focus seems
to be very different than with other lenses. Which makes the comparison
difficult. Your DLSR most likely records autofocus points: it might be a good
idea to actually display them in the JPEGs, because at such high apertures you
really want to look at what's in focus.

OP here, we sort of screw up on that one.

Should have done at least two groups of auto focusing and manual focusing.

The car scene was done in a a little rush because the sun is moving. Not sure
what's going on with the sigma but we made sure the camera beeps when it
reports in focus at the medal Jaguar logo.

If people like this idea, we will get more lenses in the next series and add
Canon and other brands if possible.

Right now the original JPEG is around 14MP and very slow to load, so we had to
