Shift lenses allow you to compensate perspective distortions (converging verticals) by shifting the optical path off its horizontal axis. By doing so the projected image (rectangle) on the film/sensor plane gets distorted to a trapezoid negating the original effect.

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.

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.

Canon have an impressive range of tilt and shift lenses for their full frame cameras, offering focal lengths of 17mm, 24mm , 45mm , 50mm and 135mm . Joining the line up is this new Canon TS-E 90mm f/2.8L Macro lens, focusing continuously down to a 1:2 magnification, a very useful half life size.

The Canon TS-E 90mm f/2.8 L Macro Lens is a new specialist lens from Canon, launched at the same time as two other TS-E Macro lenses, a 50mm and a 135mm. It is a replacement for the older 90mm f/2.8 TS-E lens, which was neither macro, nor "L".

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

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...

The lens is super sharp and easy to learn to use.

Easy to use this lens, even with big hands. Well done build, smooth focusing. The image quality, sharpness best I ever seen. Fantastic to use product, food or even portrait photography. My favourite lens in the bag.

"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.
