Robin Wong:

I have recently added the Panasonic 15mm F1.7 lens into my camera bag, mainly for 2 reasons: to replace the Olympus 12-40mm F2.8 PRO as my general wide angle video lens when I am filming videos for this channel, and as a wide angle prime for my street photography sessions, replacing the too slow Fuji XF10. I have written about the Panasonic 15mm F1.7 lens before, so I am making this video to reshare my thoughts on this tiny gem for Micro Four Thirds shooters. I think it is small, light, well-constructed and delivers sharp results.

The new TTArtisan 40mm f/2.8 Macro for MFT is now in Stock at BHphoto.

And here are three new video reviews of this lens (in other mount versions):

For once something different ;)

TheNarrowBand made this cool video and writes:

Attaching your MFT camera to a telescope could not be easier today. There are a plethora of adapters and some of them do some very unique things. A few interesting ones permit you to adjust tilt of the camera and some even reduce the f-ratio of your scope so you can collect light even faster.

ATTENTION!
There are two different standards for M42. One has a 0.75mm thread pitch. The other is 1mm thread pitch. You will only find the 1mm thread pitch in European markets. While the M42x0.75mm dominates the American Canadian, Chines and Japanese markets. Both seam to have the same back focus or lens flange distance of 45.46mm.

Here is a link for the adapter that I used. https://www.ebay.com/itm/284169576224…

And the thread adapter can be found here. Just select the 10mm option.

I would recommend purchasing the adapter for M42 first. See what it is as far as thread pitch then order your 42-48 adapter should your scope need it.
