So, last year we upgraded our 4L420 (2000+) camera to the HighRes option. But thru a misunderstanding, we discovered that the HighRes option doesn't work well for a C Mount setup because the HighRes is just a larger sensor on the camera - not a more denser sensor of the same size. As a result, a C-Mount lens will obscure the top & bottom of the larger sensor, as you can see here:

So, we have a choice, we either go with a F-Mount setup - which will give us the larger resolution, but then we lose the automatic zoom, iris and focus. (there is a remote iris option, but that's it).

Or, we can revert back to the original std resolution.

This is our track/camera setup as you can see here, a camera at the top of a 12' ladder, situated about 15' away from lane 1

I'm concerned about doing the focus/iris/zoom from the top of ladder, but I really don't have an experience with this.

So, my fellow timers, what are your opinions here? Keep the HighRes and go to an f-mount setup (also, what lens would you recommend?) or go to back to std. res? We are always outside, usually bright sun, but sometimes overcast conditions.

Many thanks!

the sensor is actually the same size, but with the High res you get to use more of it. For years I prefered the manual C mount over my remote one. Main reason was that I'd be switching between two different finishlines using just one camera. manual zoom, focus and F stop ment doing that faster. With the C mount and High res you can use about 660 pixels without too much fall off. The F mount lens will cost more and if you go for a zoom will likely have a higher F stop number. so does not do as well in lower light. To make F lenses cheeper for a camera I've picked up some Nikon mount film camera lens at pawn shops. but they are still F2.8 or so which means the camera needs 4 times more foot candles of light to get the same results as a F1.8 C mount lens. To me it is not so much a question about which lens to use but are you going to use the higher caputer speeds that come with the high res.
