SLR Gear:

The Canon 14mm f/2.8L is a sturdy smooth-functioning lens that exhibits very good Center Sharpness across its f/2.8-f/22 aperture spectrum on both full-frame and sub-frame bodies. Corner Sharpness is, at best, mediocre; Chromatic Aberration is quite poor; Shading is reasonably good; and Distortion is average. Interestingly, the Canon 14mm f/2.8L ($1800) would appear to outperform (by a slim margin) only the Nikon 14mm f/2.8 ($1420). Whatever, the overall performance of the Canon 14mm f/2.8L is a bit of a disappointment (as was that of the Nikon 14mm f/2.8). READ FULL REVIEW

The Tamron AF 17-50mm f/2.8 XR Di II LD Aspherical [IF] is a very serious performer capable to deliver some of the best MTF50 figures to date in this lens class. Vignetting and distortions are about average for a lens in this class. CAs are very high at 17mm and 24mm. Mechanically the lens isn’t top notch but it compares very well here to other third party lenses. AF accuracy could be a little better on the Nikon D200. Thanks to the very moderate price tag the lens is highly attractive and definitely worth a deeper look when shopping for a quality standard zoom lens for your APS-C DSLR and it’s also a very interesting alternative to the genuine Nikkor standard zooms. “¦ READ FULL REVIEW

Canon 70-210mm f/4 EF Review Round-Up

Ken Rockwell:

The Canon EF 70-210mm f/4 is sharp and works great. The optics are as good as similar current lenses in actual use, although it’s soft at f/4 and 210mm. The reason to pay more for the newest lenses are features like Image Stabilization, not optical quality. READ FULL REVIEW

The Canon EF 28mm f/2.8 may not be the most attractive lens on the market but it is still interesting nonetheless. It is very affordable in combination with a pretty impressive optical performance (except CAs) and quite decent mechanics. However, it faces pretty stiff competition from the Sigma AF 30mm f/1.4 EX DC HSM which is a little better in the center but worse at the borders. The Canon is much cheaper though. READ FULL REVIEW

Nikon 28mm f/1.4 D AF Review Round-Up

If you own or have used this lens, let us know what you think! Leave your comments and thoughts below.

Regarding the obvious centering defect it is difficult to find a verdict for the Nikkor AF 28mm f/1.4D. Assuming a valid sample the performance should be great when stopped down a little. Even in its less than perfect state the tested sample performed better than the AF 28mm f/2.8. CAs, vignetting and distortions are very well controlled for a lens in this class. The build quality is superb. It is a pity that the lens has been discontinued – more so because Nikon does not offer any replacement nor any other ultra-fast wide-angle fix-focal AF lens.

Photo Zone:

In lens land there’s no such thing as a free lunch and the EF-S 18-55mm f/3.5-5.6 II is an example for that. Under controlled conditions (stopping down two stops at 18mm) the lens can provide very decent results – certainly more than enough for casual users who are the target group anyway. However, technically the resolution is mediocre all-in-all and at 18mm @ f/3.5 it’s downright poor. Distortions and vignetting are very high at the wide-end but no big issue at the tele end. The construction quality is soso at best. In its price range there’re few alternatives in Canon EOS mount and they probably aren’t better either. However, serious users looking for a good quality lens should save a little longer and look elsewhere. READ FULL REVIEW

Since the release of the EOS system we have seen several updates to Canon ultra-wide zoom lenses but they didn’t really care about their fix-focals in this range ever since their initial release back in the early 90s. The Canon EF 20mm f/2.8 USM feels a little dated by now – less so regarding its mechanical qualities but optically it isn’t really something special anymore. Most good quality zooms can match its quality by now. The fix focal lens can still convince regarding distortions and CAs. Resolution-wise it is still a good to very good lens for sure – just not more than that. Vignetting is a little on the high side at f/2.8 which is a little disappointing for a full format lens tested on an APS-C DSLR. So unless you require an affordable, large aperture lens in this range there’re few reasons left to favor this lens over e.g. the Canon EF 17-40mm f/4 USM L. READ FULL REVIEW

Photo Zone

The Tamron AF 24-135mm f/3.5-5.6 AD Aspherical (IF) SP is indeed a worthy competitor for the Canon EF 28-135mm f/3.5-5.6 USM IS. The resolution and vignetting figures are slightly superior whereas it’s a tie regarding distortions. The Tamron shows a rather weak CA characteristic though. The build quality of the lens is very decent but it leaves a little to be desired regarding AF speed. Due to the 1.6x cropping factor on APS-C DSLRs the range isn’t all that attractive than it used to be so shopping for a new ones seems rather pointless regarding the existing alternatives. However, on the long term Canon users may see mainstream full frame DSLRs where the lens could show its old qualities again. “¦ READ FULL REVIEW

Nikon 105mm f/2 D DC AF Review Round-Up

If you own or have used this lens, let us know what you think! Leave your comments and thoughts below.

Photo Zone

The DC-Nikkor AF 105mm f/2 D is a very high quality, versatile tele lens. The resolution figures are excellent when using the Nikkor as a conventional lens. The Defocus Control (DC) feature gives you superior control over background and foreground blur … Vignetting, distortions and lateral CAs are very low and nothing to worry about in the field. The build quality of the lens is excellent whereas the AF (relying on the slotted drive screw) is a bit dated by now. The DC-Nikkor has one major drawback – its price tag. At around 1000 â‚¬/US$ it costs about as much as the Nikkor AF 85mm f/1.4 or the new Zeiss ZF 85mm f/1.4 – two other excellent but even faster “portrait” lenses. READ FULL REVIEW

Photo Zone

The Tamron AF 90mm f/2.8 Di SP is a superb lens without any significant flaws and it’s easily as good as the corresponding (classic) Micro-Nikkor – the resolution figures are extremely high, vignetting is marginal, CAs are low and distortions are non-existent. The build quality may be slightly inferior in comparison to the Nikkor but then the price tag is also substantially lower so the verdict can only be – HIGHLY recommended! READ FULL REVIEW
