The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 7.5mm F2 MFT and the Olympus ED 8mm F1.8 Fisheye for their suitability to various photography scenarios:
Size and Weight Comparison The size of a lens is a crucial factor to consider when comparing two lenses. Olympus ED 8mm F1.8 Fisheye is the longer of the two lenses at 80mm. The Venus 7.5mm F2 MFT with a length of 55mm, is 25mm shorter. Besides being longer, the Olympus ED 8mm F1.8 Fisheye also has a larger diameter of 62mm compared to the Venus 7.5mm F2 MFT's 50mm diameter.
Below you can find a scaled side-by-side image of Venus 7.5mm F2 MFT and Olympus ED 8mm F1.8 Fisheye to get a better idea of how their sizes compare in real life.
