Oh the speed! The blazing speed!
OK, that’s a stretch. But this is the fastest wide lens I’ve got by a pretty good margin, the previous leaders in this category holding the line at f/2.8. Jumping from that to f/1.8 is fairly significant, but “Oh the fairly significant speed increase!” just didn’t sound as good.
Much as with the swap of my Canon 28/3.5 for a 28/2.8 that I recently reported here, this was neither a planned acquisition nor a particularly necessary one. Rather, it was the result of an opportunity and the realization that I could make it happen with little additional cash outlay if I sold something I already had. In this instance, the decision was easier, in that the Serenar (Canon) 35/2.8 I had, nice lens that it is, was simply not getting much use.
Unlike the 28mm focal length, where I had (and still have) one and only one LTM lens, the 35mm field was a bit more crowded. In addition to the 2.8 Canon, I also had my lovely W.Acall 35/3.5 and my hacked Nikon L35AF 35/2.8 glass in an LTM mount; the Jupiter-12 35/2.8 that was my first foray into this focal length had already been sold for lack of use. The thing about these lenses is that each has it’s own signature, and the differences are on par with what one expects in the more common 50mm lens offerings. The Canon and the W.Acall are both double-Gauss Planar-type lenses, but the former tends toward a slightly harder look, while the latter is gloriously creamy. The Nikon follows the Sonnar formula, but with a somewhat more modern feel than is typical due to design and coatings. The Jupiter is a Zeiss Biogon copy, a non-retrofocal design, and looks quite different as a result (but apparently not different enough for me to keep it around, though that’s more the fault of the ergonomics, which are not terribly user-friendly).
When the 1.8 appeared for sale, deciding what to sell was not terribly difficult. The W.Acall, the most recently acquired of the crop, was not going anywhere – the rendering of that lens reminds me of my Summitar, perhaps my favorite 50mm lens. The Nikon hack is, well, a hack – I did have a couple people express interest in buying it back when I first showed it, but it’s not a showpiece so getting a meaningful amount for it (I have a lot of hours in putting it together, even if it looks a little more like an arts and crafts project than a proper lens) would be unlikely. Plus I like the compactness of it. That left the Canon. It’s a fine lens in lovely shape, complete with the original caps, case, and matching viewfinder, but I just wasn’t using it. So the usual dance was initiated: try to sell one lens in order to fund another. It didn’t take too long, and soon the 1.8 was on its way to me.
Once it arrived, in spite of it being quite serviceable as-is, I went through it and gave it a detailed cleaning and refreshed the lubricants. The construction of the 1.8 is lighter than the older all-brass 2.8, with the focusing barrel made from aluminum. The shape of the new lens is more cylindrical as well, and a substantial void between the optical block and the outer shell adds to the feeling of lightness relative to exterior dimensions. There’s nothing wrong with the construction, but it clearly reminds anyone who has used the older lenses that they have encountered something from a newer generation.
All well and good, you say, but how does it perform? Well, let me tell you. It’s nice and sharp in the center even wide open, getting predictably soft in the corners. Both the corners and the out-of-focus areas, which are often going to be quite prominent when shooting wide open, exhibit some interesting characteristics. Both exhibit a bit of “movement,” looking a little swirly at times and somewhat busy, and out-of-focus areas in the center lose a notable amount of contrast, though this contrast loss is less pronounced out toward the perimeter of the frame. It’s an odd effect, though one that could be useful. Stopped down it’s predictably sharp, with moderate contrast and fairly high resolution. I haven’t tested it with color yet, but with B&W it falls closer to vintage rendering than modern.
While I’m sure I could be happy with the Canon 35/1.8 as my only 35mm lens, it doesn’t quite reach the very high rendering benchmark set by the W.Acall. For low light shooting, or perhaps as an all-purpose travel lens, the Canon might be the better choice however – two stops is enough to make a meaningful difference in real-world use. As a bonus, this also works as a fast 50mm-equivalent on my Fuji X-E1, which adds to the flexibility of that camera as well.
