It’s maybe just discernibly less sharp at the rule of thirds intersection, but if it is, not in a way that is visible except at 1:1 peeping. Bearing in mind that a real human eye occupies the same size as both eyes and the area between them in the banknote, at portrait distance this shows that it matters very little much where you place your eye or what aperture you use. Left is centre, right rule of thirds intersection. This is at 1:1 pixel dimensionsįirst, wide open at f2.8. Any further into the corners in an unlikely location for an eye in a portrait.įor reference, the two eyes of the Ben Franklin in this image together are about as wide as a regular human eye. I focussed first in the centre, and then at the rule-of-thirds intersection. I focused at 2.5 metres, which is a nice half-body to head-and shoulders distance for portraiture.

Instead I have focused on bank notes, which we also often use for MOD (minimum object distance) tests.
In past reviews I have used a live subject and focused on their eye, but this both requires a cooperative friend, and is subject to possible movement. What matters here is not so much even resolution across the frame, but that the eye of your subject, at whatever place you put it in the frame, is sharp when you focus on it. Many buyers of this lens may want it, therefore, to double as a portrait lens. One of the primary uses of a general short tele lens is for portraiture. At every other location/aperture pair at infinity the Laowa is as good as, or better than, any lens I’ve tested. The Voigtlaender 110 is still a touch better in the extreme corner for the first couple of apertures, but only really visibly so at 100%. This is amazing for a lens which can do twice life size macro it’s about as good over most of the frame as some of the very best short tele lenses that can’t do macro.Ĭomparatively my review copy of the Laowa 90 is better than my review copy of the 100 was at all apertures and locations in the frame. And the very slight softness in the extreme corner is not visible even a little bit away for the corner. The extreme corner is very good wide open (better than the 100) and it gets a little better as you stop down. I focussed when the subject was central, and did not change focus for midfield (intersection of rule of thirds lines) and extreme corner, so the effects of field curvature are not hidden.Ĭentre and mid frame are both basically as good as I can distinguish from open. As usual in my recent reviews, I have taken to moving the camera so as to get the same subject in each location, to make comparison easier. Here’s the usual infinity resolution image.
All versions have a 13 blade aperture ring which keeps bokeh balls nice and round. The Sony version, reviewed here, has no electronic contacts so there is no EXIF, and stabilisation will be 3 axis. The focus throw is a bit longer than the 100mm which is very welcome about 140 degrees between 1:1 and infinity, which makes focus at longer distances much easier. and is perhaps a touch stiffer than ideal. The same is true with the new lens, so we sill see in the vignetting section whether the same problem exists. That grease lining is one of the suspects I have for the relatively poor flare performance at longer distances: as the lens focusses further away, the true front element receded, exposing more of the grease lined barrel. The nice thing about the old design was that, provided you kept the filter in place, you in effect had a cheaply replaceable front element! I can see why, but the bad thing about that is that it can’t be replaced easily. Perhaps because of that Laowa have fitted the new lens with an immovable front glass.
That was a big mistake: there is grease lining the inner barrel, and dust getting in would be not good at all. I noticed one reviewer did a test to see if that filter was optically necessary, concluded it wasn’t, and removed it. The 100mm lens came with a fitted 67mm filter. At closest focus the front element gets very close to the end of that barrel. But like the 100 before it it’s not really an internal focus lens: the trick is that there is an outer barrel, and as you focus closer, the lens extends inside that outer barrel. The lens does not change in length as you focus from 2x life-size to infinity. It’s hard to imagine better in a metal helicoid finish. The build quality is really nice.Markings are engraved and filled, it’s tightly constructed from metal and has what seems like a durable and attractive finish.
