Our unique lens comparison widget lets you view test data for a wide selection of lenses, and compare them to each other at a range of apertures and focal lengths. First select the lens, then an appropriate test camera. You can use the control dials below the display to change focal length and aperture, and can switch between three views (for Sharpness/CA, Vignetting, and Distortion) by clicking on the tabs at the top.

To compare two lenses, click on the 'compare' link, which will open a new page with a second copy of the widget. Simply select the second lens and explore the data. In this mode you can use the cursor keys to change the focal length and aperture for both lenses together (up/down to 'zoom', left/right for aperture).
Home Lens Reviews. Our lens reviews are based on detailed testing in an optical lab and real world shooting. We also provide hundreds of user reviews from photographers like you. The basic steps in testing the lens are: Purchase or print an SFRplus or eSFR ISO test chart and mount it on a flat surface. Photograph it in an environment with even, glare-free lighting. Use the View/rename Files module to rename the files to more meaningful names, based on EXIF data contained in the file. For example, the name.

Below are links to six printable targets. All are sized for 16-inch (410 mm) stars. All are binary (not sinusoidal). There are three stars for Epson printers, which want 360 ppi input images, and three for Canon printers, which take 300 pi images. To download a file, right-click on the link below, then choose 'Save as…'.
Don't downsize these targets before printing them. Send them to your printer driver at 360 ppi in the case of the Epson files, or 300 ppi for the Canon ones. If you want to print on smaller paper, crop the targets, but print at 360 or 300 ppi. If you want bigger targets, let me know how big, and I'll create some and post them here.
These are monochromatic files. When you open them in Photoshop, you'll see something like this:
Since every pixel in the files is either pure black or pure white, it doesn't matter what grayscale profile you assign. Gray Gamma 2.2 is as good as anything.

And here's a really big file (12000×12000 pixels, 200 spokes), for those making a really big target. There's a fair amount of aliasing towards the center, but that should all be a blur in actual use.
