So after spending a week reading all about Zeiss lens in this forum and the beautiful pictures that they produce, I took the plunge and bought the Zeiss 35/1.4 ZF.2. I use it with my D90. From what I've been reading and from my initial experience with it, the bokeh is amazing. However, I heard the resolution of this lens wasn't its strong point compared to the 35/2, but since I don't own the 35/2, I decided to test and compare the resolution with my Nikon 25-70/2.8G at 35mm.
I took shots at f2.8 and f4 for both lens (at 35mm for the Nikon). I viewed the raw file in Picasa at 100% zoomed in (just ordered Lightroom and still waiting for it). I was disappointed to discover that the Nikon has better resolution in the center at both apertures than the Zeiss 35/1.4! However, the Zeiss was slightly sharper along the outer edge.
Is this normal? Did I get a bad Zeiss sample? I thought Zeiss was king of resolution. Considering that the Zeiss is a prime lens and is more expensive than my Nikon, I would expect it to perform better at the center than the Nikon. Does anyone have a similar finding about the resolution of the Zeiss 35/1.4 lens?
