One of the biggest strengths of micro 43 cameras is the abundance of high quality lenses that are available for the format. But can a non-native lens work effectively on a micro 43 camera? Watch this test of a vintage Minolta 50mm f1.7 Lens on a Panasonic GF2 Micro 43 Camera. Here are several examples of desirable F stops with pulls (pull speed varies and there is no focus assist in place for this barrel). Auto Correct is dropped on these clips in Adobe Premiere Elements 10, so there is some color correction.
The Minolta lens featured in this video (and many other classic lenses) are inexpensive, can be readily found and are easily used on Micro 43 cameras by using inexpensive adapters.
Below is the link to the Minolta 50mm lens used in this video as well as the Panasonic GF2, the new GF5 and a Micro 43 adapter for the Minolta Lens.
