EF 24-70mm f/4L IS USM Review

The Canon EF 24-70mm f/4L IS USM (price & specs) is about to become a highly popular lens, at least this is the impression if you look at the many EF 24-70mm f/4L IS USM reviews that are published. The latest comes from slrgear. Some excerpts from their review:

  • The 24-70mm […] offers sharp results, but is also the subject of some controversy for its performance at 50mm. We tested three copies of this lens; the first and second had poor performance at the 50mm setting.
  • Stopping down the lens does improve its sharpness: corner softness is never completely removed to provide tack-sharp results from corner to corner on full-frame, but it is dramatically reduced. Peak performance is shown at ƒ/8 across all focal lengths
  • Results for chromatic aberration with the 24-70mm ƒ/4L were good: overall, CA is kept under control through the majority of the frame
  • On APS-C sensors corner shading is not an issue, but on full-frame: the lens creates images with corners that are significantly darker than the center. In the worst case, 24mm at ƒ/4, the extreme corners are a full stop darker than the center
  • […] testing for distortion shows a complicated pattern with a point of near-zero distortion.
  • Going from infinity to close-focus takes well less than one second, and point-to-point focusing is lightning quick
  • the lens offers an impressive 0.7x magnification [for macro]. There is also some slight fine-tuning adjustment available for zoom and focus in the macro setting

As you have seen, they are nor very satisfied with the performance at 50mm (sharpness-wise). Moreover, they found inconsistencies among copies of the lens (not good Canon!). It is hence wise to test the lens at 50mm before buying it. The issues at 50mm reflect also in the conclusion:

Canon made a smart decision to offer a lower-priced alternative to its 24-70mm ƒ/2.8, in order to give Canon shooters of the more casual or economical nature a way to stay true to the brand name. Unfortunately the lens’ performance at 50mm stands out as unacceptable, especially when you consider [it] still costs $1,500. […] So what is a Canon shooter to do? If you’re happy with the performance you see from our sample pictures, and you need or want the image stabilization and macro capabilities of the 24-70mm ƒ/4, then you should be happy with your purchase – assuming you get as good a copy as we did […]

There is always the alternative to go for the good old Canon EF 24-105mm f/4L IS USM (price & specs), which offers a wider range and the same specs as the 24-70mm. And the 24-105mm is known not only to be a lens of proven quality, but also to have consistent optical performance.

Metabones Speed Booster First Impressions (DPreview)

Metabones Speed Booster First Impressions

DPreview tested the Metabones Speed Booster for Canon EF lenses to Sony NEX mounts ($599, click here). They used a [shoplink 10206]Sony NEX-6 (price & specs)[/shoplink] for testing. All the marvels this adapter promises to deliver are once more confirmed. It is, definitely, a game changer. I think we will se great thing in the near future done with this adapter. In their conclusion DPreview writes:

There’s a lot to be excited about with a product that so transforms lens behavior and addresses such a long-standing issue for photographers who long for the wide-angle and light-gathering performance of their older full frame lenses on their newer APS-C body. Image quality is very impressive, with results that compare exceptionally well against a full frame sensor. You do pay a small price in terms of corner softness and CA.

The biggest remaining challenge, however, with the Canon EF to Sony NEX mount is AF speed, a direct consequence of pairing a PDAF-optimized lens on a CDAF sensor. And to their credit, Metabones makes it very clear that AF performance is going to lag far behind what you’d get by using the Sony NEX’s conventional AF system.

This does effectively make the Speed Booster an even more niche product, as it’s best suited for manual-focus shooters. We’d be keen to see a camera manufacturer license this now-proven technology and offer this optical quality and near-full-frame performance mated with an effective AF system. But for now, we tip our hats to Metabones for releasing a product that accomplishes what many had thought nearly impossible.

 The optical quality is outstanding. DPreview’s first impressions comes with samples and good technical description.

In this video, we take a look at Canon’s 24-70mm f/4 L IS lens, which seems to fit in right between the 24-105mm f/4L IS and the Canon 24-70mm f/2.8L II. Or does it? With less range, does it seem like a worse choice than the 24-105mm, which is considerably cheaper? Watch the video to find out.
