Canon 24-105mm Lens

Description

The Canon 24-105mm lenses are among the most popular standard zoom lenses, offering a versatile focal range from wide-angle (24mm for landscapes, architecture, interiors) to short telephoto (105mm for portraits, travel, and everyday shooting). This 4.4x zoom covers many common scenarios without frequent lens changes. On full-frame bodies (like your EOS 6D), it provides the full intended field of view. On APS-C bodies (like the EOS 1500D/Rebel T7 or 7D), it behaves as a ~38-168mm equivalent, still very useful but less wide at the short end.

Canon has produced several versions in EF mount (native on your DSLRs) and RF mount (for mirrorless EOS R-series). The constant f/4 L-series models are the most sought-after for professionals and enthusiasts, while variable-aperture or non-L versions prioritize affordability and portability.

1. Canon EF 24-105mm f/4L IS II USM (Best Overall for EF DSLRs – Recommended for Your Setup)
Released in 2016, this is the refined second-generation L-series version. It improves on the original Mark I (2005) with better optics, stabilization, and build while maintaining the constant f/4 aperture.

Key Specifications:
• Focal Length & Aperture: 24-105mm, constant f/4 – f/22
• Lens Construction: 17 elements in 12 groups (includes 4 aspherical elements; Air Sphere Coating for reduced flare/ghosting)
• Diaphragm Blades: 10 (rounded) — smooth, pleasing bokeh
• Minimum Focus Distance: 0.45 m (1.48 ft), max magnification 0.24x (at 105mm)
• AF System: Ring-type USM (fast, quiet, with full-time manual focus)
• Image Stabilization: 4 stops (improved and quieter over Mark I)
• Filter Size: 77mm
• Dimensions: Approx. 83.5 × 118 mm (3.3 × 4.6 in)
• Weight: Approx. 795 g (28.1 oz)
• Other Features: Dust- and weather-resistant (L-series build with magnesium and plastic elements), zoom lock switch (prevents creep), fluorine coating on front/rear elements, EW-83M hood included

Performance Highlights:
• Solid sharpness across the frame, with good contrast and reduced chromatic aberration compared to the Mark I.
• Constant f/4 aperture allows consistent exposure and depth-of-field control throughout the zoom range.
• Effective IS for handheld shooting in lower light.
• Good color rendition and flare resistance; some softness or distortion at extremes (correctable in-camera or post).
• Works seamlessly on your EOS 1500D, 7D, or 6D.
Strengths: Versatile “walk-around” lens with pro-level durability, weather sealing, and optical quality. Excellent for travel, events, landscapes, and portraits. Pairs well with your 50mm and 85mm primes for complementary coverage.
Limitations: Heavier than non-L options; not as sharp as prime lenses or newer RF versions, especially in corners wide open. No Nano USM.
Best For: Users of EF-mount DSLRs like your 6D (full-frame benefits) or 7D/1500D who want a durable, constant-aperture zoom.

2. Canon EF 24-105mm f/4L IS USM (Original Mark I – Still Capable Used Option)
Released in 2005, this was a workhorse lens paired with many full-frame bodies. It has slightly less advanced stabilization (about 3 stops) and optics but remains sharp for most uses.
Key Differences from Mark II:
• Lighter (~670 g) and slightly shorter.
• 18 elements in 13 groups; 8 diaphragm blades.
• Older IS and more prone to flare/CA in some conditions.
• No zoom lock on early copies (some suffer from zoom creep).
Many photographers still use well-maintained copies successfully, especially if budget is a concern.

3. Canon EF 24-105mm f/3.5-5.6 IS STM (Budget / Lightweight Alternative)
Released in 2014, this non-L lens targets enthusiasts seeking a lighter, more affordable option with good video performance.

Key Specifications:
• Focal Length & Aperture: 24-105mm, variable f/3.5-5.6 – f/22-32/36
• Lens Construction: 17 elements in 13 groups (2 aspherical + 1 UD)
• Diaphragm Blades: 7 (rounded)
• Minimum Focus Distance: 0.4 m, max magnification 0.3x (better close-up than L versions)
• AF System: STM (stepping motor) — smooth and near-silent, ideal for video with Live View/Dual Pixel AF
• Image Stabilization: 4 stops
• Filter Size: 77mm
• Dimensions: Approx. 83.4 × 104 mm
• Weight: Approx. 525 g (much lighter)
• Other: No weather sealing, plastic-heavy build, zoom lock
Performance: Decent sharpness for the price; good for stills and video. Variable aperture means slower shutter speeds at the long end in low light.
Strengths: Lightweight, quiet AF, affordable, close-focusing.
Limitations: Slower aperture at telephoto, less robust build, softer corners compared to L-series.
Best For: Beginners on the 1500D or those prioritizing portability over constant aperture/pro build.

4. Canon RF 24-105mm f/4L IS USM (Best for Mirrorless / Future-Proof)
Released in 2018 for EOS R-series. Native RF mount delivers superior performance in a more compact package.

Key Specifications:
• 24-105mm, constant f/4
• 18 elements in 14 groups (3 aspherical + 1 UD)
• 9 rounded blades
• Minimum focus 0.45 m, 0.24x magnification
• Nano USM AF (fast, smooth, quiet — excellent for stills + video)
• 5-stop IS (coordinated with in-body IS on some bodies)
• Filter: 77mm
• Dimensions: Approx. 83.5 × 107.3 mm
• Weight: Approx. 700 g
• Features: Customizable control ring, weather sealing, fluorine coating
Performance: Noticeably sharper (especially edges/corners) with better contrast and aberration control than EF versions. Superior for hybrid photo/video work.
Strengths: Modern optics/AF, lighter than EF L II, control ring for quick adjustments.
Limitations: Requires adapter for EF bodies (adds bulk/weight).
When to Choose: If transitioning to mirrorless (e.g., EOS R series).

Other Notes
• A lighter RF 24-105mm f/4-7.1 IS STM also exists for budget mirrorless users (variable aperture, very compact at ~395 g).
• No f/2.8 constant version in this exact range (Canon has RF 24-105mm f/2.8 L for pro video, but it’s much larger/heavier).

Which One Fits Your Cameras?
• On your EOS 1500D, 7D, or 6D (EF DSLRs): The EF 24-105mm f/4L IS II USM is the top recommendation — constant aperture, weather sealing, and versatile range make it a true “do-it-all” lens. It complements your 50mm (everyday/natural) and 85mm (portraits) perfectly for travel or events.
• On full-frame 6D: Best image quality and bokeh potential.
• On APS-C: Still excellent, though consider wider primes for true wide-angle needs.
• Budget/portability focus: Go for the EF f/3.5-5.6 IS STM.
