Canon EF 35mm f/2

When Canon scrapped the FD mount in 1987 and bet the whole company on the all-electronic EF system, it had a lineup to fill fast. The 35mm f/2 arrived in 1990 to plug the cheap-wide-prime hole. No ring USM, no exotic glass, just Canon's small, slow AFD (Arc-Form Drive) motor doing an honest job. It was the lens you bought when you wanted a real 35mm without paying for the 35mm f/1.4 L, and for twenty-two years it stayed exactly that until the IS version replaced it in 2012.

Wide open at f/2 it is soft and a little glowy, with visible coma in the corners and field curvature that drags the edges out of plane. People either hate this or build their whole look around it. Stop down to f/2.8 and it tightens noticeably; by f/4 to f/5.6 the center is genuinely sharp and the corners catch up. Contrast is moderate and on the warmer side, the way older Canon primes tend to render. The five-blade aperture is the tell. Stop down and out-of-focus highlights go pentagonal, which is the single most common complaint about this lens and the reason the 2012 IS redesign moved to eight rounded blades.

It is a street and documentary lens first. The 52mm front element makes it tiny, it disappears on a film EOS body like the Elan or the EOS-1, and 35mm is the classic reportage length, wide enough for context but long enough that a face you step in close on does not distort. Nobody mounts this for landscape pixel-peeping. They mount it because it is light, it focuses down to a quarter meter, and it stays out of the way. Flare resistance against a bright source is mediocre, so a hood earns its keep.

The honest weakness, beyond the busy bokeh, is the autofocus. That old motor is slow and audible, and it hunts in low light, which is exactly the situation a fast 35 is supposed to own. That is the real reason the IS version exists, and it is why used copies of this original sit so cheap.

Which is the whole argument for buying one now. On the used market it is one of the least expensive ways into a fast EF wide, cross-shopped against the Sigma 35mm f/1.4 Art (sharper, heavier, four times the money) and the Canon 35mm f/2 IS (smoother bokeh, also pricier). For film shooters who just want a small, fast, full-frame 35 on a 35mm EOS body, the price is hard to beat. One metering note. At f/2 in dim interiors you are working at the edge of handholdable, so meter wide open in Zone Light Meter and let it confirm the shutter speed before you trust the room. The lens will resolve fine down there. The shake in your grip is what gets you.
