well that looks damn sharp. I'm not even seeing a difference from center to edge on the brick shots. I wonder if that hosting program is actually sharpening when you zoom in even though he says the images are unsharpened. they just don't look like unsharpened scans to me.
The thing I really need to do first is figure out what kind of hood I will have to get for the J9. Can someone tell me what diameter filters it takes? At 85mm I suppose I can get some generic hood. Thanks.
Regarding the Zoomify image. How the program works is that it takes the large version, in this case a 2400 dpi scan, and it subdivides it into a number of smaller pieces.
Even if it sharpens the individual pieces, it still wouldn't be able to create sharpness when it doesn't exist in the original. Soft corners in a photo can be easily seen, and no amount of sharpening can change that.
For example, if the photo were unsharp in the corners, you would be able to see this and sharpening the image would simply give you more pronounced grain in what would still be an unsharp image. You would be able to notice a smearing of the image in the corners.
When I originally bought this lens, I used it side by side with a postwar 85/2 Sonnar, and I fully expected the Sonnar to visibly outperform the Triotar. Imagine my surprise when the Triotar held its own against the Sonnar.
I since have bought a prewar Triotar but haven't yet shot with it. (I'm currently in the midst of a fascination with Agfas -- mostly the simple Karat models.)
If it comes down to price, the postwar Triotar is a good lens. Keep in mind that it probably will need to be serviced. Another alternative is the postwar 135mm Sonnar. This is one of the sharpest lenses that you'll encounter.
I hope this helps you, and I hope that I haven't blathered on for too long.
