I've messed with tilt (and shift ,and swing, etc) mainly on a 4x5 camera, but I've always wanted to mess with it more or less on the likes of 35mm format. Ever since switching to m4/3 on account of mainly using old orphaned lenses most of the lens I use are adapted. And I noticed that most of the native tilt lens are roughly 8 degree's capable such as this adapter shown here: Tilt Pentax Lens Adapter for Micro 4/3 Olympus E-P1 E-P2 E-P3 E-PL1 E-PL2 E-PL3 | eBay I use an Olympus Pen E-P3, and I already use a SMC Pentax-M 50/1.4 (via PK to MFT adapter) and Tamron 90/2.8 1:1 (via Adaptall to MFT adapter, but I can easily make the 90/2.8 into a Pentax-K mount since I got the adaptall mounts for that). So was thinking of that Pentax-K to MFT tilt adapter. The problem that comes to mind however is that unlike native tilt lens I imagine that the degree of tilt and it's visual impact will probably be significantly reduced due to the fact that the micro-4/3rd sensor is roughly a 2.0x crop over full frame, as such the shallowness I could hope to achieve is also significantly lower. I guess what I'm looking for is someone who has actually bothered to adapt a 50 or 90 to a MFT camera (or similar crop) with such a tilt adapter and how did they like the result.
