FYI, here's a deal on that expires in the next two (2) days. The Rokinon 24mm T/1.5, 35mm T/1.5, and 85mm T/1.5 Cine lenses are bundled for an extra savings or $250 dollars. Available in Canon, Nikon, and Sony E/A mounts, but they can easily be adapted to fit M4/3 cameras as well. As far as Rokinon Cine Lenses go, these are probably the most popular and the deal ends March 2nd. Check it out via B&H (found here)
Rokinon Cine Lens Bundle Deal 24mm, 35mm, 85mm T/1.5
The BlackMagic Design Cinema Camera was announced in April 2012 (last year) and is still on backorder with every retail store. There are quite a few consistently listed to auction via eBay, but just be prepared to pay a bit more than the $2995 suggested retail price. Check out the listings via eBay (click here).
These lenses already in exist in the Rokinon lineup, and the Cine versions are about $50 bucks more with a de-click aperture, relocated markings, and built in lens gear. Check out the new Cine lenses from Rokinon over at B&H following the link (Click Here).
The new 35mm Cine Lens will have a lens gear built around the housing, and de-clicked manual aperture ring to adjust exposure on the fly. First lenses will come in Canon, Nikon, and Sony mounts, but as one wise commenter mentioned you could just go for the Nikon version (since it's a manual lens) and find simple adapter to fit just about everything else.
[Update] Rokinon will also be announcing a new 14mm T/3.1 & 24mm T/1.5 Cine Lens. At this time, only the 8mm T/3.5 Fisheye is already available, and 35mm T/3.1 has been just been released for pre-order, but you'll be able to check out the entire Rokinon Cine Lens collection over at B&H (Click Here).
The Rokinon 35mm F/1.4 is surely a nice lens to have in your kit - especially nice when there's a discount available. Normally about $500 dollars, today it's part of Amazon's Lightning Deals which is usually the best price you'll find anywhere. The deal was so good last time (just $350), I ended up buying a couple for my friends who missed the sale. They also only run a limited quantity during these sales so be swift. Check it out at the Lightning Deals page (Click here).
Just talking about how well reviewed the Rokinon 85mm F/1.4 lens was, and now here's a bit about the Rokinon 35mm F/1.4. First off, this is the same as the Samyang but since it's a different name, you'll save about $100 dollars off the retail price.
For Nikon, the Rokinon 35mm F/1.4 lens actually has a 'focus confirmation chip' built in. Why did they not include this for the other brands? The Rokinon 85mm F/1.4 comes in at an excellent price range, and I would say very affordable. This new 35mm F/1.4 sounds good, but it's going to have some very very stiff competition. In this area you could still get the wildly popular Sigma 30mm F/1.4 for cheaper, and that comes with full Auto Focus.
The Sigma 30mm F/1.4 has already been proven out in the field and is a very sharp lens for cheaper than than the Rokinon 35mm. The Sigma 30mm is just a tad wider, but that's a good thing especially for cropped cameras. If prices don't change, in my opinion the Sigma is the lens to get. A quick note to Micro Four Thirds shooters - the Sigma 30mm F/1.4 has been discontinued for Four Thirds cameras. If you're considering this for a GH2 (would need an FT to MFT adapter), there might be a few left in retail spots like Amazon Here, or check a few eBay Auctions Here.
