Thanks. Its a plastic igloo which is a part of alight installation at singapore river.
Yup agreed, the f2.5 is sharp too. I've used 4 different variants of the 105mm lenses, namely the f1.8 AIS, f2.5 AIS, f4 AIS micro and the latest f2.8 AFS VR micro. All are impressive performers. Given the chance I want to try out the f2.8 AIS micro and f2 DC as well.
Below is a 400% crop form a photo taken with a D700, straight from the camera except resizing. It is cropped at the worst possible area, extreme bottom right corner (where the yellow umbrellas are) of the FX frame wide open at f1.8, iso 100. Note the lack of CA. With the D700's low pixel density, this much can be revealed. I wonder what would be resolved with a D800e at f8. :think:
To say the truth, all lenses, even the cheapest kit lenses have great resolution. Problem is, most photographers, myself included, are limited by our own creativity and vision to fully utilise such capabilities to the maximum. To quote from one article in luminous-landscape, "Most lenses are better than most photographers". What I think is that people should spend more time enjoying photography than to go around shooting brick walls. Granted, I was once caught in the quest for the sharpest lens once too. :embrass: I would go around shooting newspaper to check each of my lenses's sharpness. ._. And I still do it whenever I buy a new lens. Maybe thats because sharpness is the easiest to quantify, compared to microcontrast, rendering, bokeh in the transition zone, colour accuracy, etc.
