General Notes:
1.) Korean Samyang Optics Co. is known since the 1980s for being a manufacturer of generic lenses, mostly long focal length tele and mirror lenses as well as some shorter ones (including the 18-28mm F4.0-4.5). The more recent lenses are sold under several labels including Bell+Howell, Bower, Opteka, Phoenix (discontinued around 2007/2008), Pro-Optik, Rokinon and Vivitar in the US, Polar in Asia, Walimex in Germany and the UK, Falcon in Poland and TKL in Italy. Lenses branded Samyang are available as well all over the globe, and btw. earn a very good reputation.
Samyang is further claimed by some to have been the manufacturer of Cosina and Vivitar AF lenses (Denis' Konica & Nikon Photography Pages, I think his assumptions are based on - regarding AF lenses somewhat misleading - material formerly published by Monaghan). Not sure how this fits in with AF lens world reality actually. Basically, everything that says Made in Japan won't be Samyang, and that's just most of them. To name the most obvious oppositing facts, the only AF Samyang lenses I know of are the above 28-70mm and the 100mm Macro, while Cosina has "them" all, unlike any other of their former rebadgers.
2.) The AE versions feature electronic circuits to transmit aperture values from the camera to the lens as well as to support focus confirmation (see Lens Comments for availability).
3.) The XP (eXcellence In Performance) Premium MF lens line introduced in 2016 is advertized to deliver 8K video and 50MP still photo resolutions. The barrels are made of aluminum. The first 2 lenses still didn't feature dust and moisture sealings. However, they do feature almost fully compatible electronic mounts - the only thing missing is Autofocus.

  • Kelda is the house brand of UK based distributor Kauser International. They sell rebadges of the usual current suspects, but actually claim to buy them from a China based company called Changchun Kaili Optronics Co., Ltd., in case obviously another rebadger. Also it's curious to see that the 2 lenses above are rebadges of the same Samyang lens that as such have only been offered by Opteka, who also started the rebadge as golden ringed 6.5mm and later switched to 8mm with the release of the new red ringed design, only that Opteka started to sell the rebadges early enough to still catch the old design in time. However, the rebadges are yet to be confirmed as none of the provided product pictures actually show the lenses branded as Kelda (or Kaili).
