Lens Reviews Help
Full screen mode
This allows you to display the widget in a new full screen window for maximum legibility. Its is also used to show the results from two lenses side-by-side below in 'Compare' mode: both lens selection menus become available, so you can freely switch between any pair of lenses for comparison. Click on the image below to see 'Compare' mode in action.
Sharpness comparisons between lenses tested on different cameras must be treated with a fair degree of caution; whilst we've tried to keep the playing field as level as possible, differences in imaging qualities (and most notably the strength of the text cameras' anti-aliasing filters) will affect the results. This not an issue in the regions where the lens isn't very sharp anyway, but can limit the measured MTFs at higher frequencies.
Click here for a comparison using the same lens (the excellent Olympus Zuiko Digital 50mm F2 Macro) tested on two cameras with identical sensor size and pixel count, but very different anti-aliasing filters (the Olympus E-3 and the Panasonic L10). The E-3's strong anti-aliasing filter results in rather lower MTF-50 numbers, most evident at apertures around F4 where the lens is at its best; the L10 shows a much lighter touch in comparison. Note however that this is a fairly extreme case; most of our test cameras have rather lighter anti-aliasing filters than the E-3.
Note that all of the other lens properties tested (chromatic aberration, distortion and vignetting) are not expected to be dependent upon the camera body used.
This button allows you to generate a web link to a specific state of the widget, which can then (for example) be embedded into forum posts to illustrate points being made in a discussion. Click on the permalink button, double click to highlight the text, then copy the link and paste it where necessary. Prepare for war!
