Ilford 12 x12" Multigrade Printing Filters are used for printing the Ilford Multigrade range of papers on black-and-white enlargers.  Ilford produces complete sets of filters for all contrast grades in half grade steps.

The twelve multigrade filters are in sets and are numbered 00-5 in .5 steps. The lowest number corresponds to the softest contrast.

Multigrade filters are supplied in 3, 6 and 12" square sizes to fit most enlarger's filter drawers, or as a set of mounted hard plastic filters for below-lens use in a filter holder.

Multigrade filters do not require any recalculation of exposure times when changing between grades 0 and 3, grades 4 to 5 simply requiring twice the exposure.

Easy to Use    No Complicated Calculations Required    Compatible with All Multigrade Papers

Easy way to control print contrast using variable contrast paper

Exposure time for filters 00-3.5 is the same; that for filters 4-5 is double

Q: 1. What f/stop does this lens have at 35mm?

A: The aperture number increases Linearly with the zoom. If I use A mode and set the initial aperture to f2.8 and turn the zoom up, the aperture will move to 2.9,3.0,3.1... 3.9, 4.0 to reach 60mm.

Q: 9. How does this compare to the a6500?

A: Both cameras are excellent image and video makers, having very good balanced spec s for both video and photo. The major differences are as follows: A6500 is a bigger camera, A6500 has a mic input, A6500 does 120 fps in 1080p, finally the a 6500 is a fast focusing camera. Some major differences between Sony mirrorless vs Panasonic are the sensor size; Sony has a APSC senor which is larger than Panasonics micro four thirds. Also Panasonic has a much larger lenses line up than Sony. Lastly with Panasonic you can pull a photo from the video with their 4K photo mode.

Q: 10. A consistent failing of similar designs (re-branded under countless names) is that 3-4cm of the outer edge is unable to be lit because the inward taper at the large end of the funnel is too aggressive (basically the inner reflector is nearly touching the diffusor). Is this design appreciably more bowl-shaped such that this would be alleviated?

A: I inserted wire into the seams to stiffen the 'funnel', but there remains some tapering light fall-off toward the edges, but I can't quantify in cm or f-stop.
