I wondered whether just uprezzing the image from the 50-200 might be better. However, there are two issues. One is how much better? if it's marginal then it's not worth the trade-off. This is why side by side examples would be nice. Second is whether the C-AF for the 50-200 SWD is on a par with the m.43 75-300. Static images I can manually foucs but BIFs and/or action are a different story.

I'm really only interested in the long end.

OK, here we go.

I searched the old test-pics in lightroom and I found 2 typical candidates. Both shot from a tripod with the same distance (tripod mount).

  1. A bookshelf from 4m distance (200mm@f5.6 and 300mm@f8)
  2. The moon from xxxxxxxm distance (200mm@f7.1 and 300mm@f7.1)

The books really are in focus for the 75-300, no cheating, I checked it. And no cheating while upscaling: simple export to photoshop as TIFF, scale picture by 150% using bicubic scaling smooth, save TIFF.

While the 7-300 has no perfect focus point, you can be somewhat sloppy when focusing, the 50-200 has ONE point which is very sharp. Unfortunately with my EM5 it was quite a torture to find this perfect focus manually. This has improved drastically with the EM1's PDAF.

And NO, this 75-300Mk2 was not a bad sample, before I had the 75-300Mk1 which was even less sharp.

100% crop: 200mm (bicubic upscale) and 300mm
