Olight Osight Reflex Sight 3 MOA Red Dotoffers an easily visible red 3 MOA aiming dot and a magnetic cover that charges the sight and displays available battery power. The Osight offers all the advantages of reflex sights: fast target acquisition, both-eyes-open situational awareness, unlimited eye relief, and parallax-free performance. The dot can be set to one of 10 brightness levels for daytime use or two more for use with night vision gear; you can also lock in one level or let the sight choose, based on ambient light. Impact point adjusts at 1 MOA per click with the included tool, and you have 40 MOA of adjustment for wind and bullet drop.

The charging cover has a display that shows the battery level of both the cover and the optic. The cover is USB-C rechargeable, while the optic is charged magnetically. The cover can charge the optic up to three times when fully charged.

The Osight will run for up to 70,000 hours on its lowest output setting. Even at its brightest setting, it can run for over 17 days, and this duration can be extended to over 70 days with support of the fully charged charging cover.

Featuring a generous 0.94 x 0.85" window, the optic ensures fast and accurate target acquisition and makes for successful follow-up shots.

Q: 6. I just got this lens for an Olympus EM1-ii. Can't seem to get the focus peaking to work. Works fine with the one other manual focus lens I have. Is there some limitation with being 400mm or f/8?

A: According to Olympus, they state this must be an isolated lens issue. There is no in-camera reason for lack of focus peaking. You simply need to customize a button to focus peaking usage. Tap the selected customized button to turn on focus peaking, and tap the button again to turn off the focus peaking feature. If there is still no focus peaking, then it is really a lens issue as focus peaking depends on contrast to work; no electrical lens contacts are needed.
