The image circle, its falloff, and where the corners go dark.
Light loss follows the T-stop you set and the lens's own data. Turn on the test chart and focus falloff to see how sharp the edges stay.

The camera department's field kit. Put any lens on any sensor, see its coverage, falloff and framing, then take it to set through a director's viewfinder on your phone.


Pick a camera, a sensor mode and a lens. Coverage draws what that glass actually throws onto that sensor, to scale.

Line up an 8mm against a 25mm, or the same lens on two sensors. Specs sit in two columns, row for row, and the export is a landscape sheet you can send to the producer.

The quickest answer to "will it vignette on open gate?" A clean diagram you can screenshot into a prep doc.

Active area, diagonal, field of view, measured coverage, close focus, front diameter, the matte-box filter format, weight and mount, straight from the manufacturer's data.






Type a series and you get the set. Add a focal and you get the lens. Filter by format, primes or zooms, or show only rehoused glass.



Every lens page lists the rental houses that carry it, country by country. Each house's lens list is checked against its own website, so the answer is the inventory, not a guess.


Export one lens, a whole set or a project as a print-ready A4 report: the projection, coverage, corner light, field of view and full specs. Compare two setups on a single landscape sheet. Shot lists and MTF/VFX packages for the comp lead too.
Camera, sensor mode, lens list, framelines and camera settings for the shoot, with the crew credits on every report. Add a whole set in one tap. Share it as a single file, shots included, and it opens straight in a colleague's Coverage.


The phone's cameras zoom to the exact field of view of the cine lens on your sensor, with its falloff, framelines and camera settings drawn over the live image. Stills and clips save with tilt, dutch angle, compass heading, GPS and camera height.

Check coverage on a new sensor mode without a laptop, walk the scout with the real focal, and hand the producer a sheet.
Front diameters, filter formats, close focus and weights for the whole set, plus who rents it when the house is short.
Look through the lens on the recce, save stills with framelines and heading, and send the shot list.
Coverage and spec questions answered from the counter, with a report the client can keep.
Coverage is in beta on iPhone and iPad. Write to us with the device you shoot on and we'll send an invite.
