I have a crazy few weeks coming up. This week I will be filming at the Glastonbury festival, then next week I will be in Dubai for a workshop on virtual production with Sony’s Venice 2 camera. This will be a great opportunity for those that have never been to a virtual studio to have a look at how it all works and what’s involved – nad to see how Venice 2 is an excellent camera for VR thanks to it’s very fast sensor readout speed, frame size flexibility and wide range of frame rates. To join one of the sessions please RSVP to Omar.Abuaisha@sony.com
I was recently given the opportunity shoot some test footage with a Sony Venice II. A camera like Venice needs good glass, so I put out some feelers to see what lenses I could get for the shoot. I was offered the use of a set of the Tokina Vista primes, lenses I have been wanting to try for some time, so this was the perfect opportunity to try these interesting lenses on Sony’s newest cinema camera.
Lets cut straight to the point: I love these lenses and I loved using them with the Venice 2.
I guess I had some concerns at first over choosing the Tokina Vista’s. Lets face it, Tokina are not the first brand that springs into most peoples minds when you are thinking about high quality PL cinema lenses. But I had been hearing nothing other than good things about them and when I had played with them at a couple of different trade shows, they did always look nice.
There are currently 8 lenses in the Vista range starting at the very wide 18mm and going up to 135mm. All are t1.5, are beautifully constructed with all metal bodies. The focus and aperture rings (with approx 300 degrees of travel) are in the same position on every lens in the set, so lens swaps are easy. The 9 bladed iris works well to give pleasing smooth bokeh.
Many manufacturers claim that their lenses have minimal breathing and this is definitely true of the Tokina Vista. Focussing from near to far resulted in only a very small change of the image size on all the lenses I tried. The breathing is truly minimal.
As I was shooting using the Venice 2’s 8.2K 17:9 mode this was a good test of the lenses resolution and sharpness. In the video at the bottom of the page you will see a couple of shots where I added a slow post production zoom in to the image, reaching 2x magnification. If you watch the video in 4K you won’t see any appreciable drop in image quality during the zoom in where I am in effect expanding the original 8.2K pixel image by 200%. This to me is a clear indication that these lenses are plenty good enough for 8K capture.
But, at the same time I also felt that the lenses were not excessively sharp. There is a “roundness” to the images from these lenses that I really like. The Vista’s are also very slightly warm looking and this combined with the roundness of the image and very slight propensity to flare a little gives them a very appealing look. I guess I could describe it as a vintage look, but that might make them sound old fashioned. These are not old fashioned lenses, these are clearly modern, high performance lenses. But the images they deliver has a beautiful, almost old school look that I found to be very appealing.
Faces and skin tones looked really nice, of course this is a combination of both a great camera and great lenses, but the colour reproduction from the combination of Venice 2 and the Tokina Vistas was very pleasing.
I did have a play with most of the lenses in the set and they all appeared to perform similarly. But for the video shoot in London I focussed on the 18mm, 40mm and 135mm lenses.
The 18mm is very wide. It is not truly rectilinear, there is some barrel distortion, but nothing too severe. You do have to remember that this is a t1.5 lens and it’s not easy to produce very fast, very wide lenses for full frame. The 46.7mm image circle of all the Vista lenses means that they comfortably cover the full frame Venice sensor and even at 18mm there is barely any light fall off or vignetting at the edges of the frame.
One of the other things that really impressed me with all the Vista’s was the lack of chromatic aberration. Even when shooting very high contrast, backlit edges or specular reflections it was hard to spot any chromatic aberration. There is not a single shot amongst all of the material that I shot where I noticed anything nasty.
The only negative I can really find about the 18mm is the size and bulk. This is a big and heavy lens. All the Vista have the same external diameter of 114mm. The 18mm is no different in that regard. But the 18mm is one of the longest lenses in the set, it’s 180mm from front to back. And it weighs almost 2.7Kg. A big part of the weight probably comes from the bulbous front element of the lens – which you will be glad to know does not protrude beyond the end of the lens housing, giving it some protection from accidental damage.
When you have an 8K camera, wide angle lenses can be used to capture a very wide frame that can then be cropped into to re-frame in post, so having that maximum t1.5 aperture which helps maintain a shallow DoF is important.
The 40mm lens is also really nice. 40mm is an interesting focal length, a shade longer than 35mm and wider than 50mm. I found it to be a very nice focal length for a lot of different types of shots with the Venice Full Frame sensor. At 2.24kg it is a much lighter lens than the 18mm and a fair bit shorter at 160mm. Once again extremely small amount of breathing and near total lack of chromatic aberrations makes this a lovely lens to shoot with. When shooting high contrast point light sources such as street lights at night there is a bit of circular flare around the light source, but I find this to be quite pleasing. Strong light sources just out of frame can lead to some minor veiling flare on all the lenses in the set, but this is no worse than seen with most other similar quality lenses and the lens coatings give the flare a slight warmth that again, I find very appealing.
The 135mm lens doesn’t disappoint either, shooting at 135mm and t1.5 delivers a very narrow depth of field. As expected this is one of the larger lenses in the set. It’s 187mm long so a bit shorter than the 18mm but it is heavier with the PL mount version coming in very close to 3kg. There isn’t much more I can say about this lens that I haven’t covered with the other lenses, extremely minimal breathing, near zero chromatic aberration etc all make for a great image. The consistent look across all the lenses means this too shares that well rounded not too clinical and very slight warmth that makes these all of these lenses very appealing.
The Tokina Vista’s are not re-housed photo lenses, they were designed specifically for digital cinematography. They are available in a range of mounts including PL, Canon EF, MFT, LPL and Sony E. I had heard good things about them from other users before I tried them and now I have had a chance to shoot with them I have to say that they are lenses that I will want to use again. Perhaps in particular when the project would benefit from a slight vintage or romantic look without being soft and without giving up any resolution. For the money they are great looking lenses and would recommend anyone that hasn’t tried them to give them a go.
