I set myself an exercise last week and carried it on through Saturday’s shoots. The exercise was to shoot wide open with the Zeiss Planar T* ZE 1,4/50 lens. A lot of people with the Leica M9 shoot wide open, with lenses costing $3,500 or more and, as you may expect, the results are pleasing.
The 50mm Zeiss Planar T* ZE lens however disappoints wide open at f/1.4. It is not as sharp as it could be and people who test lenses in the lab, such as SLRGear.com and Photozone, give the detailed analysis behind that assertion. But at f/2, the sharpness kicks in.
Another downside to shooting at f/1,4 is that the bokeh can be a little harsh, with bokeh fringing, and the lens also suffers from Longitudonal Chromatic Abberattions (LoCa). At f/2 these effects disappear. Bearing those shortcomings in mind, f/2 was as wide open as I intended to shoot with this lens.
With a such a wide aperture, the depth of field is incredibly narrow and focusing has to be spot on. The Canon 40D like a great many DSLRS is devoid of any focusing aids in the viewfinder, so manual focusing can present a challenge at the best of times, let alone at f/2.
The general advice for focusing manual lenses is to bracket the focus. I will bring the object into focus, or as in focus as the 40D’s viewfinder shows, and then gently adjust the focus in small increments and firing off another shot with each focus adjustment. I usually end up with between four and six shots of the same subject and then select the best one in Adobe Bridge, making use of the magnifying loupe.
It is time consuming but the results achieved by a Zeiss lens make it all worthwhile. Zeiss glass has its own signature and one that I prefer to almost any other brand of lens. Those with more technical knowledge than me suggest that the micro-contrast of Zeiss lenses is what gives the subsequent images their distinctive look. I just know that I like and prefer Zeiss lenses.
I shot at two locations on Saturday — Jacksonville Farmers Market and St Marys, Georgia. Yes, it was time for the cigarette run again.
Farmers markets afford great photographic opportunities in terms of the people who visit and those who work on the stalls. The fresh fruit and vegetables on sale also make good subjects.
Here are two shots at f/2.
At St Marys, I headed for a boat ramp on the North River. I had seen the signpost pointing to it on several previous visits but never got round to checking it out. The road to the boat ramp runs past the site of the Durango paper mill, formerly the Gillman Mill, which went bankrupt in 2002 and was demolished in 2007. The old industrial site also made a good subject.
Here are two more shots at f/2.
