The Ultimate Buying Guide: Choosing Your Canon EF Mount Lens
Canon EF mount lenses offer a huge range of options for photographers using Canon DSLR cameras. Whether you shoot portraits, landscapes, or fast action, there’s an EF lens for you. This guide helps you pick the best one.
Key Features to Look For
When shopping for an EF lens, several features really matter. These determine how well the lens performs.
Focal Length
Focal length tells you how zoomed in the lens is. Shorter focal lengths (like 18mm or 24mm) give you a wide view, perfect for big landscapes. Longer focal lengths (like 200mm or 400mm) zoom in tightly, great for sports or wildlife. Standard lenses (around 50mm) are close to what the human eye sees.
Aperture (f-number)
The aperture is the opening inside the lens that lets light in. It’s shown as an f-number (like f/2.8 or f/5.6). Smaller numbers (like f/1.4 or f/2.8) mean a wider opening. This lets in more light, which is great for dark situations. Wide apertures also create that nice blurry background effect, called bokeh.
Image Stabilization (IS)
Image Stabilization helps keep your photos sharp, especially when shooting handheld or in low light. Canon calls this feature IS. It physically moves lens elements to counteract small camera shakes. If you often shoot without a tripod, look for lenses with IS.
Important Materials and Build Quality
The construction of the lens affects its durability and weight.
- Lens Elements (Glass): High-quality glass elements make a big difference in sharpness and color accuracy. Canon uses special coatings on these elements to reduce glare and ghosting (flares caused by bright lights).
- Lens Barrel: Most modern EF lenses use strong plastics or metal alloys. Professional “L” series lenses often feature robust metal construction and weather sealing.
- Weather Sealing: If you shoot outdoors in rain, dust, or snow, look for lenses marked with weather sealing. This protects the internal parts from the elements.
Factors That Improve or Reduce Quality
What makes one lens sharper or better than another?
Factors That Improve Quality:
- Prime vs. Zoom: Prime lenses (fixed focal length, like 50mm) usually offer sharper images and wider maximum apertures than zoom lenses.
- Large Aperture: Lenses with a constant, wide maximum aperture (like f/2.8 across the zoom range) capture more light and offer better background blur.
- Special Glass: Look for terms like UD (Ultra-low Dispersion) or Fluorite elements mentioned in the specs. These correct color flaws and boost clarity.
Factors That Reduce Quality:
- Older Autofocus Motors: Very old EF lenses use slower, louder autofocus motors. Newer lenses use faster ring-type USM (Ultrasonic Motor) or STM (Stepping Motor).
- Chromatic Aberration: This appears as color fringing around high-contrast edges. Good lens design minimizes this.
User Experience and Use Cases
How you plan to use the lens guides your choice.
Portraits:
You need a lens that captures faces beautifully and separates the subject from the background. A 50mm f/1.8 (the “nifty fifty”) is cheap and excellent. For professional portraits, 85mm or 135mm lenses with wide apertures (f/1.8 or f/1.4) are top choices.
Sports and Wildlife:
Speed and reach are essential here. Look for long telephoto lenses (100mm and up) that have fast autofocus (USM) and Image Stabilization (IS). Constant f/2.8 aperture zooms (like a 70-200mm f/2.8) are professional standards.
Travel and General Use:
Versatility wins here. A standard zoom lens, like a 24-105mm f/4, covers most everyday situations without forcing you to change lenses often. They are usually lighter than professional fast zooms.
10 Frequently Asked Questions (FAQ) About Canon EF Lenses
Q: What is the difference between EF and EF-S lenses?
A: EF lenses fit both full-frame and crop-sensor Canon DSLRs. EF-S lenses are designed only for Canon’s smaller, crop-sensor DSLRs. EF lenses work on both types of cameras.
Q: Are used EF lenses safe to buy?
A: Yes, many used EF lenses are reliable workhorses. Check the glass for fungus or deep scratches. Test the autofocus motor to ensure it sounds smooth and focuses quickly.
Q: What does “L” mean on a Canon lens?
A: “L” stands for Luxury. These are Canon’s professional-grade lenses. They feature superior optical quality, robust build, and weather sealing.
Q: Do I need Image Stabilization (IS) if I use a tripod?
A: No. When the camera is perfectly still on a sturdy tripod, IS is not needed and sometimes can even cause minor issues. You can usually turn IS off when using a tripod.
Q: Which EF lens is best for low-light photography?
A: Any lens with a very wide maximum aperture (a small f-number like f/1.4 or f/1.8) lets in the most light, making it best for dark scenes.
Q: How does aperture size affect depth of field?
A: A wider aperture (smaller f-number) creates a shallow depth of field, meaning only a small part of the image is sharp, blurring the background nicely.
Q: Can I use EF lenses on mirrorless cameras?
A: Yes, you can use EF lenses on Canon EOS R mirrorless cameras using an EF-to-RF adapter. The adapter lets the lens communicate perfectly with the camera body.
Q: What is “back focus” or “front focus”?
A: These terms describe focus errors where the lens consistently focuses slightly behind (back focus) or in front of (front focus) the exact point you aimed at. Good quality lenses minimize this.
Q: Should I buy a prime or a zoom lens first?
A: If you are starting out, a versatile zoom lens (like an 18-55mm or 24-105mm) is a good start. If you know your preferred style, a prime lens (like a 50mm) offers superior quality for less money.
Q: What is the quietest autofocus motor for video?
A: The STM (Stepping Motor) lenses are generally the quietest for video recording because they are designed to be smooth and silent during continuous focus adjustments.
