rokinon lenses?

[xpiotiavos]

Anyone have any? are they any good?

[mel_unruh]

I don't have any currently. Rokinon lenses were from Ricoh. Although Ricoh had a couple of bodies that were actually pretty good, they are generally regarded as being sub-par. They used a hybrid K mount which allowed their bodies to use Pentax lenses. But, as I recall, it didn't necessarily work the other way. In other words, if you have a Rokinon lens with the Ricoh mount, there may be some compatibility issues when used with an actual Pentax body. So, unless its free or pretty close to it, I think I'd pass.

I picked up a 28mm f/2.8 on ebay for about $10, which is close enough to free for my taste. If it's any sharper than my DA 18-55 @ 28mm, I'll be happy. If it isn't, I'll probably use it for target practice or something... ought to be entertaining enough.

The name of the Ricoh lenses is Rikenon and they will not fit a recent Pentax body.

I picked up a 400mm f/6.3 Rokinon lens some time ago on eBay, from a pawn shop in Las Vegas. Dead on arrival. They refunded the purchase price (about $10) and told me not to bother sending it back.

 

These are fairly pedestrian lenses. I just wanted to see if I could still hold-hold 400mm.

 

Of course, the vendor had thrown in what they described as a little tripod, which turned out to be a Bogen tabletop and ballhead. Some day I'm going to use the lens as practice for lens repair work.

I think they used to have a super-fast 55mm (or 50mm) f1.2. It was said to be 'not sharp' super wide but ok after a stop. When you figure the weight of the lens it is hard to justify purchasing an optic that cost more and doesn't match a standard 50mm f1.4 from Pentax.

FYI, I use Rikenon (not Rokinon) lenses on my *istDS. They work.

 

Rikenon and Rokinon are not the same thing.

[xpiotiavos]

Well, the lens arrived. The aperture blades are oily, but that doesn't really matter considering they don't use the same mechanism as every other k mount lens. You were right, Markus. Lens actually did fit on my DL though, and as you can probably guess, it's optically laughable: much worse than my kit DA 18-55mm @ 28mm.

 

Ought to be fun to take apart at least ;).

At least some of the lenses sold under the Rikinon name were really from Cima Kogaku, who also sold them directly under the Cimko MT name. Cima sold under a LOT of different names, including Super Paragon PMC, Carenar, Cambron (house brand of the notorious Cambridge Camera Exchange), Revuenon, and more. They also made the last (low-cost) set of lenses for Topcon cameras (RE Topcor), and the AM Topcor lenses with K mount.

 

They had a US patent (4,174,167) on a system by which one lens design could be fitted with a huge variety of mounts, fixed by 4 screws.

 

I've seen them with a huge variety of mounts, including M42, Pentax K, Topcon, Canon FD, Contax/Yashica, Nikon, Minolta MD, Konica, Olympus M.

<p>Hey that 28 sounds fun you can always use it as a kind of toy camera shooting experience, should give some interesting effects.</p>

<p>My first "not normal " lens, other than my smc pentax 50mm in the mid 70's was a Rokinon 80-200 zoom. Got stolen during a trip to London. I have very fond memories and pictures to prove it was a great lens. More recently, I acquired a M42 28 mm 2.8 made/sold as a Rokinon. I find it sharper than the Minolta 28 AF on my Alpha mount system. My belief is that it was a marketing company peddling lenses, etc made by whoever, but had some stellar products. Here is a picture</p><div></div>

<p>Rokinon is OEM lens in China <strong>Shenyang web page:</strong></p>

<strong></strong><em>Sorry for only Chinese. In Product you can see a 35~200 Rokinon AI mount is OEM by this company.</em>

<em><strong></strong>So I believe currently Rokinon lenses are China made.</em>
