My Buying Guides on Canon Ef 100 300
When I decided to invest in the Canon EF 100-300mm lens, I wanted to make sure I chose the right version and understood its features fully. Here’s what I learned through my experience, which might help you too.
Understanding the Canon EF 100-300mm Lens Versions
There are a few different versions of the Canon EF 100-300mm lens, including the original 100-300mm f/5.6, the 100-300mm f/5.6L, and the 100-300mm f/4.5-5.6 USM. I found it essential to know the differences:
- The f/5.6L version is a professional-grade L-series lens with superior optics and weather sealing.
- The USM version offers faster autofocus thanks to the Ultrasonic Motor.
- The original 100-300mm f/5.6 is more budget-friendly but slower in focusing and less sharp compared to the others.
Choosing the Right Aperture for Your Needs
My shooting style influenced my aperture choice. If you shoot wildlife or sports, the wider aperture of the 100-300mm f/4.5-5.6 USM helps in lower light conditions and faster focus. However, if you mostly shoot in good daylight and want a lightweight option, the f/5.6 versions are adequate.
Autofocus Performance and Motor Type
I prioritized fast and quiet autofocus since I often photograph wildlife. The USM (Ultrasonic Motor) lens was a game-changer for me, offering near-silent focusing and quicker response than the older motor types.
Image Quality and Sharpness
From my tests, the L-series 100-300mm f/5.6L lens delivered the best sharpness and contrast, especially wide open. If image quality is your top priority and budget allows, the L version is worth considering.
Weight and Portability
Since I often hike with my gear, the lens’s weight mattered. The f/5.6 non-L versions are lighter, making them easier to carry for extended periods. The L lens, while heavier, felt more solid and durable in my hands.
Compatibility with Your Camera
The Canon EF 100-300mm lenses are designed for full-frame and APS-C Canon DSLR cameras. I made sure to check my camera model’s compatibility to avoid any mounting or autofocus issues.
Price and Value for Money
Prices vary widely depending on the lens version and condition (new or used). I balanced my budget with my needs, eventually opting for a used 100-300mm f/5.6L that offered excellent value and performance.
Additional Tips from My Experience
- Consider investing in a good tripod or monopod to stabilize the lens at longer focal lengths.
- Use a lens hood to reduce flare and protect the front element.
- Test the lens if buying used, checking for smooth zoom and focus operation.
I hope my insights help you make a confident choice when buying a Canon EF 100-300mm lens!
