Canon EF 70-300mm f/4-5.6 IS USM Lens Review (Video)


A detailed review of the Canon EF 70-300mm f/4-5.6 IS USM Lens. This is a very light weight lens, great for backpacking. I often use this lens for wildlife and flowers (on tall trees). So far no issues. Even though it is constructed out of plastic, this is one rugged lens. I have hit this on walls and other objects when it hangs on my neck, and it has been over a year and still working strong! The zoom is great, and I love the bokeh (make sure you watch the photo slideshow at the end).

If you are a beginner or intermediate photographer on a tight budget and want to start with wildlife photography, this is a definitely a must have for your kit. Remember that EF-S mount lenses are not compatible with full frame DSLRs! If you might upgrade, definitely go for a EF mount lens like this one!

Canon EF-S 18-55mm f/3.5-5.6 Lens Review (Video)


Warning: As shown in the video, I replaced this lens with one of Canon's top notch L-model lenses. The information provided in the video and video description may be slightly biased as the L-model works a lot better and gives a way better quality than this lens.

The Canon EF-S 18-55mm f/3.5-5.6 Lens is a great entry level lens for both entry level photographers and amateur photographers. The lens is light and compact and is made of plastic and glass. This is one of Canon's cheapest lenses and is usually bundled with some DSLR bundles. The lens gives off great photo quality for the price and would satisfy any amateur or entry level photographers.

Pro:
  • Light weight
  • Cheap
  • Has image stabilizer
  • Fairly good photo quality for the price
Con:
  • Not as sharp as L-models (Canon's elite lenses)
  • Chromatic Aberration at non-center
  • Aperture changes as you zoom
  • Front of the lens moves (not good for polarizers)
  • No distance window
  • Micro-motor focus (loud)
  • Light fall off at wide aperture
  • EF-S mount not compatible with some cameras

The Moon

The moon, Earth's only natural occurring satellite. A giant piece of rock floating in outer space. It is a wonderful site. Although it doesn't emit light of it's own, it reflects light from the sun so we can see at night. I recently taken some moon photos from my house, including the full moon. I hope you like them! I missed the lunar eclipse, sorry. One night of no sleep and I have very bad headache the next day, so I didn't say up. HAHA

These photos was all taken with my Canon EOS 7D at 300mm on my USM lens. I will tell you what settings I used under each photo. Hopefully it will help you take some better photos yourself! :) Also, click the photo to see the full size.

Full Resolution Photos and Prints: If you want to see full resolution photos or buy prints of any of the photos you see, they are up on my portfolio for viewing here.

Anyways, this photo, it says I used 280mm focal length. This is the only exception.

So, full moon was yesterday. That was all the good photos I took. I hope you have enjoyed it! Please leave me a comment if you loved it and share with your friends. You know, this is the first time I even tried to take a photo of the moon. Surprised I can see all the craters on the moon! Wow, what a strong camera and lens. Anyways, please like my blog on Facebook. You can also do it in the box on the top of the right sidebar.
