Strictly academic

 I tested the suitablity of Viltrox' 23mm f1.4 lens for closeup work. One shot at min focus, one with 11mm extension tube, and one (attempt) with 18mm tube. Not really surprising that the longer tube at 23mm caused the lens to block almost all light reaching the fuscia buds, so no additional testing needed! The 11mm tube performed nicely, and the Meike set passed all data along.

For a bonus, I put on the Pentax smc-M135 f3.5, both alone and with the two tubes. The minimum focus dropped from 5' to just over 3' with the shorter tube, the 18mm focused several inches closer. And to close, I pulled out the A100 f4 and shot a 1:2 closeup for comparison.

I shall post them here soon!

Winner lose, loser win

Lyric from Steve Winwood, Go 

For reasons that I accept as reasonable, a Z50 is coming soon - and the eM1 and a lens or three are leaving.

• Pros: larger sensor, smaller camera, tilt screen, USB battery recharge, Nikon menus like my former Z6, 'solitude' picture control
• Cons: no IStab inside, shorter battery life, usbμ port, plus a few Oly/OM features which I like yet never used!

Its 'starter kit' is TTArtisan 17mm + Viltrox (23, 40mm) primes, and the VRs 16-50 and 50-250mm. For now the Pentax 70+100+135 will fill the small-tele slot.

The camera comes with 3 batteries and a charger, so power won't be a big issue. 

I briefly considered a Z30, but its only view is via its flip screen; that outweighs the usbC power port for me. I rarely make use of a flip screen, but will use the tilt design frequently!

Note that the eM1² departure does not kill the μ43 kit! The gf9 and Lumix 14-140, plus a few nice primes, will carry on.

If the kit were to expand soon, I'd expect either the Nikkor 12-28 or Viltrox 14/4 to be next.
