Viltrox EF M2 II & Tamron 70-300mm vs Olympus 75-300mm for Wildlife


This is probably a super obvious test. What is better for wildlife, using a speed booster or a native lens?

The answer was clearly the native lens. The speed booster used was the Viltrox EF-M2 II with a Tamron 70-300mm F4.0-5.6 with the Canon EF mount. This was used on a Panasonic G9 Micro Four Thirds camera.

The native lens was the Olympus 75-300mm II F4.8-6.7 on an Olympus E-M1 Mark II camera.

I was wearing a dual camera harness to switch quickly and easily between the two cameras. I switched lenses toward the end of the walk. Not much came along for that part, but the G9 did much better with the native Olympus MFT lens. The EM1 did better with the adapted lens, but not as well as the native lens.

The big downfall of the speed-boosted lens was the autofocus. It was plenty sharp enough and the colors look great. There is no contest here. The native Micro Four Thirds lens was much quicker to focus on either camera. The Olympus was able to handle the adapted lens better, but I’m finding Olympus autofocus is clearly better than Panasonic.

Sample footage starts around the 2:19 mark. This was the first video I tried shooting at my desk with the G9. I feel the Olympus has done better but might try manual focus next time.

This could be a more interesting test with a portrait-style shoot. What do you think?
