Another dumb question for the day. Just got my used 8x10, cleaning it up, and i have two lenses that will cover 8x10, both are g-clarons, one is the 240mm and the other is the 270mm. Pretty close in size as you can see. Both are mounted for use with my 4x5, but I bought both thinking that eventually one would be for 4x5, and the other for 8x10.

Now that I am there, not sure which one I should mount on the 8x10? I will not be using any other lenses on my 8x10 in the near future ( I do have a couple of process lenses, but that's down the road), the one g-claron will be my "do everything" lens.

With 25 sheets of 8x10 at over $100 a box, before I experiment too much, any suggestions over which one of my two g-clarons I should try first? Anybody used both before? More concerned with the "best" for my 8x10 as first choice, either one is fine for my 4x5 work.
thanks
