Rodenstock Sironar N Compatibility

As long as you have a lens board that will take the shutter and a bellows that will allow extension to your closes planned focusing distance, you're good to go. You're very unlikely to run into any problems with movements with that lens; it has enough coverage that you'd be tying your bellows in knots before you run onto issues.

According to this list published by Graflex, there are two different Sironar N 240mm F5.6 lenses. They cast image circles of 337mm and 350mm, respectively.

The nominal negative size for 4x5 is 102x107mm with a diagonal of ≈148mm, so you won't have any issues with image circle size.

Just be sure your lens board can take a lens that large in diameter, as some 4X5 cameras, particularly "folding" cameras, can not handle a lens that large.
