Canon EF 24-70mm f/2.8L USM
Standard Zoom Lens for Canon SLR Cameras

I have the Canon kit lens – 18-55mm, but it’s only a f/3.5-5.6. When I take pictures in the house there just isn’t enough light sometimes. I have to crank up the ISO or I adjust my shutter speed so much that it just wont work for hand held. It doesn’t take long after you buy your first DSLR camera to realize f/2.8 is pretty awesome!

Now who has the best deal today… Amazon has it listed for $1329.00 + Free Shipping! Bhphotovideo has it listed for $1399.00 + Free Shipping!

Official Product Description:

The Zoom Lens EF24-70mm f/2.8L USM was developed as the successor to the EF28-70mm f/2.8L USM lens released in November 1993. Featuring a new optical system design, the new zoom lens delivers an expanded zoom range with a 24 mm wide-angle focal length, ideally suiting it to digital image sizes, while also maintaining or improving on the outstanding image quality of the superseded model.Moreover, the power of the focusing lens group has been increased to allow a minimum focusing distance of just 0.38 meters, the shortest in its class at the time, throughout the entire zoom range. The new EF24-70mm f/2.8L USM also features a circular diaphragm, to give better background blur, and utilizes only lead-free glass optics in consideration of the environment.

Technical Details:

  • EF mount; standard zoom lens; Comes with Lens Cap E77U, Rear Lens Cap, Lens Hood EW-83F, Soft Lens Case 1219.
  • Ultra-low Dispersion glass with Fluorite elements; inner focusing ring; full-time manual focus; aspherical lens
  • 24-70mm focal length
  • f/2.8 constant maximum aperture
  • UltraSonic Motor (USM) AF actuator

Canon EF-S 55-250mm f/4.0-5.6 IS Telephoto Zoom Lens

This is a great lens! My favorite part is being able to take close up pictures from a distance. You don’t have to stand right in front of someone to take a picture.

Right now it seems to be pretty close in price with B&H Photo being the cheapest at $255.00 for the USA version including shipping! Amazon is also $255.00 shipping not included. Buy.com has it as a kit $279.95 shipping not included, but it does come with some accessories.

Here is the official product description:

Incorporating Canon’s Optical Image Stabilizer technology, this Canon 55-250mm telephoto zoom lens captures long distance, low-light shots far better than many comparable lenses, helping you photograph the far-off action of athletes or zoom in for an intimate portrait with a blurred background. The high-zoom-ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses). More significantly, the image stabilizer effect creates an equivalent shutter speed of roughly four stops faster than the same size lens without an image stabilizer. In other words, if the slowest shutter speed you can hold a 250mm lens steadily is normally 1/250th of a second, this Canon lens will let you hand-hold shutter speeds as slow as 1/15th of a second. The lens also boasts a UD-glass lens element to correct chromatic aberration to create excellent image quality throughout the zoom range. Delivering an excellent performance at an affordable price for all photographers, the 55-250mm lens carries a one-year warranty.
