Fantastic images Xu88... vibrant color, lovely composition, and a beautiful model and settings to boot.
That lens was on my 'to get' list, but the need for some decent zooms for landscape work precluded my actually getting one. I am thinking that, after I pick up a tilt shift, that one will be next. I love the feeling these fast Canon L-primes give you. I've been using an 85mm f/1.2L for a good deal portrait work, and I consistently adore the out-of-camera quality I get with ultra-fast primes!
Here is just why i bought this lens, the only light i had was from a blind slightly open about 20 feet away. This is my 3 day old son boy is it great to be a DAD, Oh Canon 20D ISO800 and the 35MM at F1.4 http://www.canon20d.net/pics/mommy_joey.jpg
Wow very nice pictures... the 35L and the 135L those are two lenses on the top of my to purchase list I have used and love them both! Oh did I mention your shots were great
EF85/1.2L EF50/1.0L EF200/1.8L are USM lens, but they are not "ring-USM" , so NO FTM available.
EF135/2L EF35/1.4L EF24-70/2.8L EF70-200/2.8L EF28-135IS and many many CANON lens are "ring-USM" now, FTM available.
Maybe something wrong?
This is what Canon Camera Museum sat about one of the lenses that you say has no ring-USM. 50/1,0
An ultra-fast standard lens with the largest aperture for SLR lenses in the world at the time. Two large-diameter ground and polished glass aspherical lens elements (3rd & 8th) provide high-contrast with low-flare image quality even at maximum aperture. Curvature of field is minimized through use of four high-refraction glass elements. Spherical aberration and curvature of field at close focusing distance are minimized by floating mechanism. A ring USM (Ultrasonic Motor) achieves silent, high-speed AF and full-time manual focusing.
SLR Slim and XU88........you guys are a VERY BAD INFLUENCE on me. I had to order one of these wonder lenses today for delivery tomorrow. It's like a addiction. I saw these shots of yours and I was dead meat. I sure hope this lens turns out to be as wonderful as you've portrayed it. I have a feeling it's going to be spending more time on my 20D than I figured.
I have used and love them both! Oh did I mention your shots were great
