A few days ago I wrote a post about lighting on location with LEDs. Here's how the final image looks.

Portrait Subject. 

Several days ago I wrote a post that showed how I was using LED lights to illuminate portrait subjects at a law firm here in Austin. I wanted to follow up that description of the technical stuff by showing what the final result looks like so you can better understand what I was trying to accomplish at the shoot. The image above may not be the one finally selected by the client for inclusion in their website but it is a good example of what we were going for. No major retouching has been done.

To refresh, the taking camera was a Sony A7R2, using a Rokinon 85mm t1.5 cine lens set at f2.8. My goal in lighting is to first make the subject look great while matching to a consistent look for all the thirty+ images I've made for the same company over the last few months. My lighting goal is to control the color and quality of the light on the subject while effectively blending the existing light from three different, continuous sources (exterior through the windows (blue/cyan), mixed spectrum florescent, and more yellow spectrum from compact fluorescents in ceiling cans). The effectiveness of precisely targeted, custom white balancing can not be underestimated.

That's it. 

(Sorry for the delay between the first blog and the example photo. I wanted to receive permission to use my client's portrait before posting it here. Not necessarily required but very appropriate....).

The Rokinon 85mm t- 1.5 Cine Lens Photographs chef, David Garrido.

As part of our restaurant project for Garrido's I was asked to make photographs of the chef (and owner), David Garrido. We made images in the kitchen with David surrounded by staff and we made images of David on the patio, but the ones I liked best are the casual ones of David sitting in front of the "tile" wall.

I would love to regale you with stories of how I lit this and I would love to jump into a lively discussion about the virtues of LED versus flash and more. But the reality is that the light coming through a west facing wall of windows in the late winter afternoon was as nice as any lighting I could have designed.

The real story in the image is the lens and camera combo I used. I'd just gotten the Rokinon 85mm 1.5 cine style lens and I was excited about shooting just about anything on which I could train my camera. I put my Sony a99 camera on my wooden, Berlebach tripod, set the exposure to something like 1/30th at f2.8 and blazed away. Jeez.... I didn't even add a reflector for  fill...

Am I happy with my new acquisition? You bet. Best lens purchase ever for $340.

I used the same lens yesterday to do a video interview for Zach Theatre. Well, it was one of the lenses I used. We decided to do a two camera set up in order to have footage to cut away to. I used the 85 R on the a99 as our primary, frontal camera and I used a Tamron 28-75mm 2.8 on an a57 about forty five degrees over to one side as a secondary camera.

I just reviewed the footage from both cameras in Final Cut Pro X and I was delighted all the way around. We have an incredible array of choices at our disposal these days. Next time I'll try the 85mm R on the Sony Nex 7 and see what APS-C's highest quality sensor can do with a speedy lens.

Crazy Photographer buys Wacky Off Brand 85mm Lens. Why? What was he thinking?

The 85mm t-1.5 Rokinon Cine Lens. Yum.

 I've been around the block long enough to know that there's no free ride. But I've also racked up enough lens purchases to know that there's also a lot of wiggle room between quality, branding, features and price. So you'll have to forgive me for going off the reservation and purchasing a wacky newcomer to the 35mm lens market, the 85mm 1.5 Cine Rokinon lens.

A couple of weeks ago I did a test with the 85mm 1.4 CZ for the Sony. While I'm a sucker for cool lenses and I would definitely toss one in the bag is the price was right I was also very underwhelmed by the center performance of the lens wide open. You may want a homogenous sharpness across the full frame but I'll trade some corner performance for center sharpness any time. Like it or not, the important and juicy stuff usually winds up in the middle of the frame. (Please don't be too literal, I'm talking about the inner 70% of the frame not the little 10% chunk right in the center...).

While I am deeply and irrevocably in love with the cool little Sony 85mm 2.8 lens I have found a few situations (mostly in video production) when I'd really like to use a decent 85mm 1.4 lens at its wide open aperture. So when I started having second thoughts about the venerable Zeiss offering I also started to look around at other options, like the Sigma. That's when I discovered this particular lens. The Rokinon 85mm t-1.5 Cine version of Samyang's well respected and inexpensive 85mm 1.4 still photography lens. I'm increasingly interested in the intersection of still photography and motion so this lens caught my attention for several reasons. First, the basic design is based on Samyang's latest permutation of their still lens and countless reviews have made it pretty clear that its optical performance is competitive. Secondly, the lack of click stops is a great thing for quiet interviews and other video situations where you might need to compensate for a light shift during a live take. Finally, the lens looked cool in the product advertising and it was dirt cheap compared to everything but my little 2.8. I figured I could compare it to what I saw with the CZ and if it wasn't as good I could send it back for a no hassle refund. A quick test with no harm done.

Short story: It's not going back. Long story? It toasts the Carl Zeiss lens for center sharpness wide open.  And to my eyes it's at least as good at the rest of the f-stop range as well.

The 85mm t 1.5 Cine mounted on a Sony a99.

As you can see in the image just above the lens has it's t-stops (actual light transmission stop as opposed to theoretical f-stops) running down the side of the lens when the camera is in a normal position. That's because filmmakers tend to prefer apertures on the side because there are so many attachments that loom over the top of their full configured cameras that getting to the ring and seeing the settings can be....challenging.  You'll notice that the focusing ring is rotated into this position as well. 

The focusing ring is deeply scalloped and it's done that way so it will mesh with most of the follow focus units that are on the market. Those are the units that use a geared attachment to the focusing ring so that accurate focusing can be done by rotating a knob. The focusing ring is also a long throw, linear ring so it's harder to overshoot your mark.

So, the lens is solid, the focusing ring is smooth as butter, the aperture ring is click-less but has enough resistance to stay put when you engage it and the whole package looks very professional. Optically, the lens is constructed with 9 elements and includes an aspheric element. I used the lens yesterday at a product shoot and stopped down to f16 without much perceptible diffraction effect on the Sony a99. Below are a couple of studio illustrations I did before I sat down to write this.

My favorite, older ball head. The Leitz Ballhead. This was shot at f4.

I wanted to see what the sharpness of the lens looked like in the center at f4. According to all the tests I've read this is where most 85mm's shape up and become bullet proof in their performance.

Here's what a 100% crop of the center looks like. 

But, if you are going to pay for a fast aperture you've got to be curious about what you're going to get as a result of your investement. With that in mind the next photo down is in my studio as well and is shot at the full 1.5 t-stop. First the full frame:

And then the 100 % crop (see below).

I'm happy with that kind of performance. But what are the downsides of a great performing but dirt cheap ($350) fast lens? Since Samyang/Rokinon didn't scrimp on image performance what got left out of the mix to hit this price point? Well, it's totally manual focus. The Nikon version has a focus confirmation chip but the Sony and Canon versions are bare-bones. That's okay for Sony users because we have focus peaking and it makes using this lens in most situations fast and accurate.

The lens also has no aperture automation. When you move the dial to a smaller aperture the lens stops down. Always. In a traditional OVF camera the finder gets darker and darker until (varies by camera) the finder gets too dark to be useful. For a number of situations it's useful to focus near wide open and then stop down and that can be a real pain in the butt. There's a reason people like automation.....

Their are two other glitches but neither of them shows up anywhere in my list of deal killers. I'll mention them anyway. First, the lens hood, while included ( take that, Olympus), is about as flimsy as it comes and most ham fisted American users will have theirs in small pieces in short order. The same sentiments for the lens cap. Look to the aftermarket market if these things bug you. I'm presuming most video users will be using a filter holder or compendium bellows shade on the front of the lens anyway and most of us still shooters have so many 72mm lens caps floating around from yesteryear's wonder lenses that it won't matter.

For studio shooters like me, and photographers who set up lights and work with maximum control, there are no real deal killers with this lens. It's a great value for us. If you do a lot of sports the long, linear focus ring will screw you up. So will the lack of automation in exposure.

My most anticipated use? Portraits. Wonderful portraits with vaporous backgrounds. I like the look of the files I'm getting enough so that the lens has not come off the front of my camera since I first got it. Your mileage will vary depending on what you'll be using the lens for but you won't be able to complain about image quality. This lens delivers that.

It is available in Sony Alpha, Sony NEX, Canon and Nikon mounts.
