Originally posted by house I meant a comparison of the images they produce not primarily the focal length. Someone who knows the lenses well might be able to find situations that show of their character. Bokeh, colours, aberrations, sharpness behaviour.
I understand, just wanted to offer an alternative point of view. I could look into my archive for some images that could compare both, but I didn't do a head to head. I think I sold the FA35 to finance getting the FA31 from a DPR forum friend moving to Olympus. And besides, my shots with the FA35 will all be 6MP only, so probably not representative for use on modern gear.
If you are not so FoV sensitive as I am, one point in favour of the FA35, regardless optical characteristics, is its ease to mount filters compared to the relatively unpractical FA31 with its fixed hood. Just in case you hadn't considered this...
