I'm advertising professional photographer since 1980 and large and medium format is what I used in this time since I have my second Canon, (my first was a Canon F1 in 1978, after that I switch to Nikon for a while) the new 5D, just after his launch into the market, I saw the TS90 in Canon's website...

I used the older version of the 90mm t-s for years. The wear of daily use made it just about unusable, despite Canon's repair of the gearing. I haven't yet examined the files to check for optical improvement, but am extremely pleased by the greater resolution of the controls.

despite of ordinary glas material (no L-series) this lens has exceptional sharpness - but the best thing about it is the unsharpness! things out of focus get blured in a special way, not seen by any other lens - even if you stop down to f11!

this lens has no competitor

rotating front element; tiny shift & tilt knobs

The TSE 90mm is an excellent lens producing super sharp, clean images on my 5D Mark II. I use this for mostly architectural detail work, the lens is very well built and very small in size by compared today's newer lenses.

Superior build quality; Super-sharp images

Need a little practice before I control lens. But a real pleasure in Black and White portraits. Beautiful object.

This is a fascinating lens overall. Although the 90MM perspective limits its use for large architectural shots, it will render details well that cannot be reached without a ladder.

Extremely well built; Sharp, unique perpective control features for a short telephoto lens

Lock knobs could be bigger

"I have been wanting this lens for some time, and decided to order one when I saw the big savings ($340). The price is competitive even compared to B&H which is a big plus as I don't need to pay for the duty and and international shipment.

This lens is superb optically. I use it mainly in the studio for table top shots. I found that it is far more flexible for small jewelry products than when I used a 100mm Macro, because of the tilt feature. I have used it with the 2x Teleconverter to achieve very close results.

Great resolution; Tilt and shift are waaay more useful than shift alone

have to modify it to change the axis of shift with tilt; a little bulky (but not bad

This tilt-shift lens is a huge improvement over the previous model that I have been using for the past 7 years. It's sharper, has more contrast, and focuses much closer. I use this lens for 90% of my jewelry shots. Great product! And, the memory card was an added bonus.

The Canon TS-E 90mm f/2.8 is one of the more unusual lenses in the Canon lens lineup - it is one of three tilt-shift ( TS ) lenses. Shift lenses allow you to compensate perspective distortions (converging verticals) by shifting the optical path off its horizontal axis.
