Why is The Bower 85mm f1.4 $100 More Than The Rokinon Version ?

I thought they were the same, is it higher quality control in Bower versions or middleman profit ?

PS: What dealer has the K mount Rokinon version for sale, I don't see any as of late ?

I think it's safe to assume all these lenses are exactly the same on the inside, and apart from the VIvitar, they all seem to be the same on the outside. I would purchase the cheapest brand (but make sure it comes with a hood).

All appear to be Samyangs. Why not contact Samyang to find the US distributor and do a deal at the distributor level. It worked for me in getting $100 knocked off the price ona Samyang 8mm fisheye lens.

it might be worth just checking the mount. K vs KA.

On many web sites you can see some product photos are K mount while others are KA mount.

I bought the vivitar from B&H only after confirming personally that it was a KA mount. My perspective was that it was worth the $50 more not to risk getting a K mount.

Having Automatic aperture is very important with respect to retaining matrix metering, and P-TTL flash, as well as more consistent exposure (especially on K10/K20)

Lowell, all the versions seem to be P/KA, but some Pentax auctions show photos of the Nikon version. I have not seen a photo of any of these lenses in Pentax mount that was not P/KA.
