So just recently I sold a bunch of my lenses and 7D to trade up to a 5D Mkii and zeiss 50mm f2.0. A couple of weeks later a family called me to do a portrait session. I was a little nervous because my zeiss is manual focus only, and I would be shooting 3 dogs, and a 2, 5, and 6 year old. I did the session and it went great
I thought some of you might be interested in how this went as well as how the lens performed. Zeiss recently started making manual focus lenses in canon and nikon mounts. In the canon version, you have all the usual metering, aperture control, and even focus confirmation. The missing element is autofocus. This zeiss lens is a couple hundred bucks cheaper than canon’s 50mm f/1.2L, and the build quality of the zeiss is far superior (all metal, even the hood, and buttery focus ring), but you do lose some weather sealing, and an f-stop. Most of the reviews state that the sharpness of the zeiss is better than canon’s L, at least in the corners — they may be equivalent in the center.
The manual focus (MF) requirement of the Zeiss lenses was the biggest adjustment after relying on AF for many years. That said, you’d be surprised at how quickly you get accustomed to MF. The first obstacle I ran into was that manually focusing the Zeiss was almost impossible with the stock focus screen on the 7D and 5D. The stock focus screen is optimized for both fast and slow lenses, but if you look through your viewfinder with a 50mm f1.4 lens, you aren’t viewing a DoF of f/1.4 (even with the depth of field preview button on). Instead, the depth of field you’re seeing is only about f/4.0 — this is due to the microprisms embedded in the stock focus screen. So, step 1 was buying canon’s “S” focus screen, optimized for f2.8 and faster lenses. With this screen installed it’s WYSIWYG when you look thru the viewfinder, and manual focusing is a much easier.
My first worry when shooting portraits with the Zeiss was, “how many shots am I going to miss?”. After a bit of practice, the answer for me is “not many”. Even with AF, when shooting kids, you’re going to miss shots. One issue with shooting AF is that you have to rely on a focus point. Previously, I usually set the middle focus point, focused on the eyes, then reframed the shot. The problem with this technique is that you have to move the camera when reframing the shot, and the subject or camera may move throwing off focus in the process.
