For non-astronomical photography, large format is used because of the versatility of large format cameras in terms of their ability to control perspective (buildings don't look like they're falling backwards) and the plane of focus (e.g. can create VERY deep focus in widefield shots), and because of the quality of image possible with the inherently large piece of film. No matter how fine your lens, film granularity limits how big you can make prints -- the less magnification required, the higher the final quality.

Both webcams are *tiny*, not much bigger than the average 20mm Plossl (the TouCam Pro is shown with a Mogg 1.25" nosepiece attached), so neither is going to strain even the smallest telescope. The LPI has a nice feature that the 1.25" nosepiece is actually a screw-on sleeve. Unscrewing it reveals a 0.965" sleeve, a thoughtful touch. Additionally, the 1.25" nosepiece is threaded for standard 1.25" filters.

At a zoom of 7.5x, the vignetting begins to diminish and is nearly eliminated at a zoom of 10x in both figures. This, however, is not due to any specific optical phenomena, but rather is a result of the digital zoom of the 707. Essentially, it is simply cropping and resizing the zoom 5x image, therefore reducing the appearance of the vignetting. Yet not all performance is about vignetting. Field curvature or flatness is also an important aspect.
