Canon EF 70-200mm f/4 USM L IS (full format) - Review / Test Report



Special thanks to Johannes Matzke for providing this lens for testing!

Introduction

Canon users were always gifted with a broad range of excellent tele lenses, especially zooms. At the time the Canon EF 70-200mm f/4 USM L hit the market back in 1999 it was another milestone but there was one itch left: wouldn't it be nice to have this lens with an image stabilizer ? In late 2006 Canon heard the calls and released the Canon EF 70-200mm f/4 USM L IS so there're now no less than -four- 70-200mm L variants in the lens line-up. However, some user calls probably went silent after seeing the price tag beyond the one grand (€/US$) barrier. Still, for many a wish came true. We have already tested the lens on an APS-C DSLR some time ago (with superb results) but its native playground is the full format so let's have a look how it performs here now.

Distortions

The Canon EF 70-200mm f/4 USM L IS does a good job with respect to distortions but the situation is still a little worse compared to prime lenses. The Canon lens produces a slight degree of barrel distortion at 70mm, slight pincushion distortion at 135mm and moderate pincushion distortion at 200mm. The latter may be visible in very critical field situations.

The build quality of this lens is excellent - no wobbling and smooth controls. The lens does not extend during zooming and thanks to its inner focusing system the front element does not rotate so using a polarizer is no problem - unless you attach the hood of course.

The lens incorporates a new third-generation Image Stabilizer (IS) with a claimed gain of 4 f-stops for hand held photography (at cost of shutter speed). This is achievable in the field but better take 3 f-stops as a guidance. Unlike the consumer variants the IS system has 2 modes - a normal one for static shooting (horizontal + vertical stabilization) and a panning mode (horizontal OR vertical stabilization - the panning direction is automatically detected). It also features tripod detection so the IS can remain activated here.

By default the EF 70-200mm f/4 USM L IS does still NOT come with a dedicated tripod mount but it is available as an option either in black or white. The lens may be relatively light-weight but used on a tripod the camera-lens balance is quite bad so if you intend to use here the optional tripod mount is a good investment.

Typical for most modern EF lenses it features a ring-type USM drive which offers near silent and very fast AF operations. There were no problems with respect to AF accuracy during our field tests either. Like its direct cousins the lens is compatible to the EF 1.4x (-> 98-280mm f/5.6) and EF 2x (-> 140-400mm f/8) converters. Please note that Canon consumer DSLRs will not provide AF with the latter combination due to the small max. aperture.

The similarities between the two 70-200mm f/4 variants are quite striking so let's have a short look at the paperwork here before going on to the test results.

Canon Rebel T1i Review


Canon Rebel T1i Review

BY: Adam Crawford, DigitalCameraReview.com Contributor
PUBLISHED: 6/19/2009

The Canon Rebel T1i is the camera company's first DSLR to feature both full HD and 720p video capture in the same camera body (the Canon EOS 5D Mark II was their first DSLR with full HD capture). The T1i comes packed with pro-quality features like an APS-C sized 15.1-megapixel CMOS sensor, the impressive DIGIC 4 image processor, a high-res 3.0 inch LCD, full manual control over exposure, and easy-to-use scene modes for everything from night portraits to sports.


With all the buzz surrounding Nikon and Canon's trailblazing DSLRs with HD video, we are starting to see an onslaught of cameras being released, from point-and-shoot compacts to pro-level SLRs, with this exceptional feature – appealing to those who need HD video and the highest quality stills all in one device. The T1i certainly is capable of both.

The T1i inherits the same technology as the higher-end 50D, packing the same-sized image sensor and DIGIC 4 processor, and giving a reviewer like myself reason to draw comparisons between the two cameras. Although technologically similar, the T1i and 50D are different in size, features, controls – and, of course, price. But it is interesting to see just how much of the 50D has made its way into the affordable T1i.

Canon EOS 450D (Digital Rebel XSi / Kiss X2 Digital) Review May 2008, Simon Joinson and Phil Askey



Review based on a production Canon EOS 450D
camera second, kamera second, info camera, nikon, canon, minolta

Four and a half years have passed since the first affordable digital SLR from Canon; the EOS 300D (Digital Rebel). In that time we have witnessed two further iterations (the EOS 350D and EOS 400D) leading up to today's fourth generation EOS 450D, with twice the megapixel count of the original (twelve versus six) in a smaller body with a far wider range of functionality and features and a $200 lower list price. Since those heady days in 2004 when the EOS 300D was the only kid on the block we've seen Nikon, Pentax and Olympus all attempt to hit the same sweet spot of size, features and price at the 'lower end' of the DSLR market, with varying degrees of success. Without a doubt the EOS 450D will have to do more today to prove itself in an increasingly crowded market.

On the third page of this review you'll find a detailed breakdown of all of the changes and updates compared to the EOS 400D but the headlines are; a larger 3.0" LCD monitor, Live View with both passive and contrast detect AF, Spot metering, improved auto-focus, 3.5 fps continuous shooting a larger viewfinder and a switch SD/SDHC for storage (all previous cameras in this range were Compact Flash). Other features appear to be inherited from the EOS 40D; 14-bit image pipeline, Highlight Tone priority, optional High ISO noise reduction, 'My Menu' and display of the ISO sensitivity on the viewfinder status line. There's also the new stabilized kit lens (for review and samples click here).

Note that throughout this review we will refer to the EOS 450D by its European name; if you live in other parts of the world you'll know the camera by (in order of silliness) Rebel XSi or Kiss X2 Digital, but they're all the same.
