Excerpt: Landscape and portraiture are my main uses. having plenty of manual focus lenses manually focusing was not a problem it simply takes a little longer. The focus confirm is very helpful.I own both this lens and the zeiss 135 APO sonnar and I must say both lenses are very nice and this 90mm for being a very old model is pretty on par, even if it not apochromatic. Its resolution is superb.
Summary: When I purchased a used lens copy of this TS-E lens, I was already familiar with tilt/shift lenses by using both the 24/3.5 I and II TS-E versions. The design of the 90/2.8 TS-E is the same one as formerly used in the 24/3.5 TS-E I lens. Advantage of this old build style is its metal lens body and better knobs to turn compared to the new 24/3.5 II TS-E lens.
Excerpt: The tilt was only half what I expected.The lens will not attach to Canon's Macro Twin Lite.The lens will focus quite close, acting as a macro lens. The lens is well made, but the shift and tilt are at right angles and should have been made adjustable so they can be combined.I would recomend this but point out the shortcomings.
Excerpt: I use this for product photography, either to isolate a detail (tilting the focus plane away from the surface of the object) or to maintain focus along the entire product when shooting at an angle (tilting the focal plane to run along the object's surface). I also use it when I need to magnify something; it's not officially a macro lens but it focuses down to half a meter, letting me get pretty close.
Excerpt: Although manual focus is old school, optically this lens is mindblowing. The build quality is on par with a L series lens. This lens has a bit of a learning curve through the additional creativity this lens provides makes it worth the effort. It has been one of the most used lens for product & portrait work.
Pros: Consistent Output, Durable, Lightweight, Strong Construction
Excerpt: I generally use the 90mm for close-up shots when depth of field and boken are important. The lens is very sharp and the boken is wonderful. I use it even when perspective control isn't needed. Fantastic when combined with 6mm extention tube.
Excerpt: I've used this lens for over a year and come back to it whenever I am working of close-ups. Great manual focusing capabilities but with live view it's spot on sharp, contrasty and of course you have the tilt shift.
Pros: Consistent Output, Durable, Lightweight, Nice Bokeh, Rugged, Strong Construction
Summary: Here's a few pics I've taken with it: http://automotomedia.net/showthread.php/82-Canon-90mm-TS-E-fun-for-taking-shots-of-cars-motorcycles! Rented a 45 and didn't like the image quality. This lense was considerably better and tack sharp when not tilted/shifted.
