Show HN: Lens Battle – Make comparing lenses easier (with leaflet.js)

OP here: some of the misalignments are caused by distortions and slight camera movement. Those are the hardest to control and require repeated try. The Sigma lens is also overly heavy that pointed the camera down-ward a little. Will try to do better in the next round of lenses.

That&#x27;s very, very nice! Thank you!<p>I noticed that on the most expensive lens, in the &quot;car&quot; 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&#x27;s in focus.

When you switch photos I might pull all the way back out. It looks like you stay focused in.<p>Meaning whatever I was focused into on the picture I was just on is not important to the new picture. So pull back out. Ha hopefully that made sense.<p>Super cool idea.

Want to see more comparison between lenses for Canon.
