Morning, Well I usually shoot landscapes, citylights and the like. However, I acquired a new Zeiss 25mm f2.8 ZK. Just saying that the lens is nice is an understatement. I really want to use it for 'scapes, but the lens has this extra additional capability. The focus throw adjustment takes 355 degrees of the 360, and close focus is at 6 inches. 180 degrees or half of the focus adjustment throw is from 6 inches to 12 inches. This coupled with the f2.8 aperture makes this (for me) a real macro lens. So, I have been playing around with it quite a lot.
In my playing, I have come across a number of things. Its spring here in the desert, well at least the previous weekend anyway - its now 100+ degrees, but the flowers were out and I went out and shot a few. What I found was that the yellow ones, especially during the day, really over drive and over saturate the metering on my K5 (center averaging). It took a while, but I am wondering if just center spot would provide better metering, so that I would not be over saturating the color, which I am finding just blows out the fine detail. This did not dawn on me until the second or third round, trying different things back on the computer post processing the images. The yellows just blow the detail out of the water. At first I though I was just out of focus, but even hand holding which is difficult, I am pretty sure that I was careful and got it, and even opened up the aperture to get a better depth of field, and the color just overwhelmed everything.
I never had a lens with this capability and its a nice weapon to have in the bag (its HEAVY, but really nice!).
Anyway - here are a few shots - with the last one showing the overblown highlights....
edit - by the way the last image was 1/2000 sec at f4 with an ISO of 400 and I was no farther than about 7 inches from the cactus needles. I kept getting the buds perfectly, but the flower details are just mush (however in the viewfinder, they appear perfectly focused with great detail).
