Don't you hate it when sellers wallpaper the Ebay pages with repetitive offers of the same item? But wait, these unbranded flash units are supposed to be specifically for different cameras - yeah, that's right, with a single contact on the shoe.
Strangely, he recommends three "different" ones for the Pentax K-1, K-1 Mkii, and the K-3. However, the K-1 apparently shares its flash characteristics with a Panasonic Lumix, while the K-3 shares characteristics with a Leica M10. From the punctuation he seems to think that Panasonic makes Pentax cameras - does he know something?
Following the link to the unit for the "
Panasonic Pentax K-1 Mkii" we find it proudly shown fitted to a Canon EOS 500D, but for all the seven photos, not one shows the back and there is no other clue as to what modes this thing has other than what looks like a sensor on the front. But contrary to first appearances it does have a tilt head!
