Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras

Canon EF 70-200mm f/4L IS USM lens offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 200mm without having to decrease shutter speed. Developed for use with a Canon SLR camera, this autofocus telephoto zoom lens offers optimized use with the Canon EOS series digital cameras. Of particular note, Canon has introduced an image stabilizer (IS) that adjusts to meet the demands of professional photography. IS reduces dramatically the image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. For shooting immobile subjects, Mode 1 corrects for movement in the image along both the horizontal and vertical axes. For shooting while panning horizontally to follow a moving subject, Mode 2 turns off vertical correction and prevents the effect of dragging the subject back through the frame. The lens' Ring-type USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. The EF 70-200mm f/4L IS USM includes distance metering information, providing compatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark II, EOS-1Ds Mark II, EOS 5D and EOS 400D. When used in conjunction with Canon's range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering. Includes Lens hood and soft pouch

Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. The L-series lens offers an Image Stabilizer that provides up to four stops of shake correction--a first for Canon IS lenses. The use of fluorite UD lens elements, meanwhile, produces an excellent optical performance in terms of resolution and contrast. Add in a sturdy housing with water- and dust-proof construction and you have a lens that's both portable and high performing. Other details include an f/4 maximum aperture, a ring-type ultra-sonic monitor (USM) that enables quick and quiet autofocusing, compatibility with circular polarizing filters, and a lightweight body. The lens carries a one-year warranty.

My wife was nice enough, at 1am in the morning, to stand in and let me take some photos of her from the wedding she participated in. I wish she could have dressed here, at home, before leaving for the wedding, which would have yielded less wrinkles in the dress.

This was a wedding, I was told not directly, that I would photograph...didn't happen; this was FAMILY too (Oh well). The best thing about this situation is that I processed and printed up the photos the same morning, finishing up at 4:30am. The next day, we were in the same vicinity that the newly married couple would be, and someone said (who was at the wedding, plus whom I never met before), "Oh, you all have your wedding photos back already?"

All the gratification that I needed not being the official photographer. Not sure to this day why I didn't photograph this event, but at least my wife gave me a chance. Love ya!

Note: I wanted to do all of my edits via Lightroom. Although I had some success from it, the constant updating of the sidecar file really slowed down the editing process at times; having to close the application numerous times. Moreover, it can be done if you have the time.

CC and CS, a couple I met in Bagac last March 12 got married last Sunday. The couple are camera enthusiasts and caught my attention as CC, had a Nikon D300S and her fiancee CS had a Canon 450D. I now wonder which camera the newly married will use. I saw the couple everywhere I went, they simply enjoyed the company of each other and would stop anywhere and take turns taking pictures of the other. When I waited for the sun to set, CC and CS were resting on a lounging chair by the infinity pool enjoying the sight of the sun going down. After my first dozen shots, CC approached me and introduced herself and her fiancee who followed a few steps behind. She asked how I took my shots. I showed her and she made a few shots and showed to CS. The boyfriend nodded in approval and told me, they will soon be married and they are planning to spend some time here after the ceremony. I just saw their uploads and indeed they got married. The lovebirds must be Bagac renewing the vows they made while in the Las Casaa Filipinas de Acuzar and enjoying their honeymoon. Best wishes and congratulations to CC and CS. Enjoy your new status in life as husband and wife.

My congratulations also to Carol (nona) who recently celebrated a 27th wedding anniversary. Cheers Carol and hubby, you have found great love, nurture it till forever.

The Canon EF 24-70mm standard zoom lens does what many pros thought couldn't be done--it replaces the L-series 28-70mm f/2.8 lens with something even better. The lens offers extended coverage to an ultra-wide-angle 24mm, making it ideal for digital as well as film shooters. The new processing unit, meanwhile, makes the autofocus (AF) faster than ever. And thanks to the two aspherical elements and a totally new UD glass element, the optics are far superior to the earlier lens. Sealed and gasketed against dust and moisture, the EF 24-70mm lens carries a one-year warranty.
