Canon EF 24-70mm f/4L IS USM Review (Photography Blog)

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

The Canon EF 24-70mm f/4L IS USM (price & specs) is the standard choice for many pros using Canon full-frame cameras. The lens has image stabilization, macro features and an ultrasonic motor for AF. Although it has a price tag of $1499 it is still cheaper than the heavy discussed Canon EF 24-70mm f/2.8L II USM (price & specs), which comes at $2199. If you can live without the f/2.8 (but there is Canon’s excellent IS instead) this lens may be the right glass on your full-frame DSLR (like the entry level Canon EOS 6D (price & specs), the cam used to test the 24-70 f/4).

Photography Blog reviewed the 24-70 f/4 posting an exhaustive review (check the various sections about the lens’ sharpness, samples images here). In the conclusion they write (emphasis mine):

Given its L-series billing, the Canon EF 24-70mm f/4L IS USM build quality is reassuringly excellent and it makes a perfect partner to a full-frame Canon DSLR like the EOS6D that we tested it with. Auto-focusing is quiet and quick, with the ability to manually override it and focus manually if required proving a nice touch. The capable image stabilisation system used in conjunction with a high-ISO monster like the 6D is a low-light shooter’s dream ticket, making it easy to hand-hold the camera and get the shot, despite the relatively slow maximum aperture of f/4.

Canon EF 40mm f/2.8 STM DxOMarked (very sharp!)

Canon EF 40mm f/2.8 STM DxOMarked

DxOMark analyzed the EF 40mm f/2.8 STM (price & specs) using a EOS 5D Mark II (price & specs), and the nifty pancake got figures:

Considering its relatively low price, the EF 40mm f/2.8 STM was a solid performer on our DxOMark Camera Lens Ratings. […] it rates among the top seven standard prime lenses (with a focal range between 35mm and 85mm) achieving an overall DxOMark Score of 26.

Strengths of the Canon EF 40mm f/2.8 STM include resolution […] Additionally, our sharpness measurements and field maps […] indicated that the lens delivered relatively consistent edge-to-edge sharpness from f/2.8 to f/11.

Other strengths include its low geometric distortion and well-controlled chromatic aberration as indicated by its low Chromatic Aberration score of 10µm.

The one weakness of the Canon EF 40mm f/2.8 STM was the strong vignetting evident at the widest apertures. You can see from the vignetting field maps below that at f/2.8, there is heavy shading across 2/3 of the field.

The Canon EF 40mm f/2.8 STM actually has price tag of $149. A bargain for a lens that has such a good perfomance (click on shop name): B&H Photo, Adorama, Amazon USA, Amazon CA, KEH Camera, BestBuy, Canon CA, Canon USA.

The 40mm pancake performs slightly better than the much pricier Canon EF 50mm f/1.4 USM(price & specs), and the cheaper EF 50mm f/1.8. As you can see, all three lenses have very good sharpness figures.

DxO Optics 8.1.2 has been released. Among many new features, support for the Canon EOS 6D (price & specs) has been added (in the Elite version of the software). Around 300 new camera and lens combinations have been added to the DxO Optics Modules library, there are now of 10,000 available Optics Modules.

DxO Optics Pro achieved the goal it set in early 2012 to have 10,000 DxO Optics Modules available by the end of 2012. Developed in the laboratory using an exclusive calibration process, DxO Optics Modules contain tens of thousands of data points about the intrinsic characteristics and flaws of each camera and lens. This database, unique in the entire world, allows DxO Optics Pro to automatically correct all the optical flaws in RAW and JPEG images – distortion, vignetting, chromatic aberrations, lens softness – with an unrivaled level of quality.

Sigma EF 35mm f/1.4 DG Reviews Round-Up

 

Sigma EF 35mm f/1.4 DG Reviews

Well, just two Sigma EF 35mm f/1.4 DG Reviews. :-)

The Sigma 35mm f/1.4 DG (price & specs), part of Sigma’s “A” (Art) line-up, is getting very positive reviews allover the web. Having a price tag of $899 it is also affordable for most of us.

Photography Blog has to say:

If the new 35mm F1.4 DG HSM lens is anything to go by, Sigma are definitely raising their game with the recent introduction of their three new lens ranges (Art, Sports and Contemporary). The Sigma 35mm F1.4 DG HSM is a fast and tack-sharp lens that exhibits low chromatic aberrations and very little barrel distortion. Vignetting at wide-open apertures is the only real optical issue of note, something that other fast lenses also suffer from, and stopping down to F/4 solves the problem altogether.

SLRgear writes:

Sigma’s produced an excellent lens in the 35mm ƒ/1.4 DG HSM, with comparatively great performance at the ƒ/1.4 aperture setting, where the lens will no doubt be used for the majority of the time. There’s a lot to like here: great results for sharpness, low chromatic aberration, and low distortion. There is some significant corner shading when used wide open, but coupled with the corner softness at the same aperture settings this contributes to an interesting look and subject isolation. If you’re looking for corner-to-corner image sharpness you’ll need to stop down. The Sigma 35mm ƒ/1.4 is definitely priced to compete, and designed to perform.
