After almost two years of consideration I becamethe owner of a Canon 50mm F0.95 lens.I finally obtained onereasonably affordably when a Westlicht Auctions in Vienna( where I live) were auctioning one at a time that coincided with my bank account having enough in it for me to bid. Thisrarelens has a small but strong followingand is often found modified to Leica M mount. Exculding prototypes there are two variants a range finder coupled and a TV version. The version I have isRange finder coupled.
My long considerationbefore purchasing was due to the combination of two important issues, cost and adaptability to my Sony A7rII. I have made the mistake in the past of leaping to buy a legacy lens, due to theenthusiastic reviews of others, and then finding it didn't perform in a manner I liked.The "dream lens", as many have come to call it,has many enthusiastic reviewsbut very few cautionary tales. Noting the usual selling price from US$2000.00 through to US$3500.00 I was concerned that the hype might not match the "bucks" needed to obtain one. The issues I was worried about before buying was Vignetting( a reported issue with Range finder lenses and FF E-mount cameras) and softness. Well I got the lens andnow after nearly a month of ownership I can say clearly both those issues are present with the lens.However I no longer care, I suspect every time I am out with this lens on my camera I am smiling.Its important to be clearthis is no where near a perfect lens; its soft, it suffers from internal reflections, flare, spherical aberration, vignetting and its heavy and clunky( built like a world war II Tank). If you want a sharp F 0.95 lens then you wouldn't want to go near this 1960s - early 1970s lens, insteadits either the Mitakon speedmaster or the Leica Noctilux you should be going for. What I wanted, and got from the lens was thedream like bokehand the 1930s film-star-glow the lens produces when wide open. If you want a legacy lens with Bokeh and sharpness you would be much better off with the Minolta Rokkor 58mm F 1.2. The Rokkor will give you bokeh andhair splitting sharpness, but what it won't do is give you the "glow".
The Dream lens seems to be a soft focus lens, a few years backI owned the Rokkor 85mm Varisoft, and that lens is the only one thatI have used that comes close to what this Canon range finder lens does. Wide open, with the right lens -subject, subject - background distances, subjects, particularly faces, get a secondary glow about them that is reminiscent of the photos taken with the Leitz 90mm Thambar.When you add in phenomenal subject background separation anda unique buttery Bokeh this is a unique art lens. It isn't for every one and I should mention one other significant fault: its size.When adapted to M mount, Leica users find they have to use a credit card ( or similar) to operate the lens release button.On the Sony A7rIIthe necessary adapter freesSony users from that problem but for those with hands and fingers larger than Donald Trumps( sorry I couldn't resist)holding the Sony A7rII with the dream lens attached is an issue. In the following photo I have markedwith two red lines, the gap between the lens barrel and camera grip.That gap is uncomfortably smalland makes managing the lens Camera combination hard. I am seriously considering getting the battery gripto get around this irritation.
