Guess The Lens! A little bit of fun and an interesting test.

XDCAM-sliding-system-v2 Guess The Lens! A little bit of fun and an interesting test.

Last week I was at O-Video in Bucharest preparing for a workshop the following day. They are a full service dealer. We had an FX9 for the workshop and they had some very nice lenses. So with their help I decided to do a very quick comparison of the lenses we had. I was actually very surprised by the results. At the end of the day I definitely had a favourite lens. But I’m not going to tell you which one yet.

The 5 lenses we tested were: Rokinon Xeen, Cooke Panchro 50mm, Leitz (lecia) Thalia, Zeiss Supreme Radiance and the Sony 28-135mm zoom that can be purchased as part of a kit with the FX9.

I included a strong backlight in the shot to see how the different lenses dealt with flare from off-axis lights. 2 of the lenses produced very pronounced flare, so for those lenses you will see two frame grabs. One with the flare and one with the back light flagged off.

I used S-Cinetone on the FX9 and set the aperture to f2.8 for all of the lenses except the Sony 28-135mm. For that lens I added 6dB of gain to normalise the exposure, you should be able to figure out which of the examples is the Sony zoom.

One of the lenses was an odd focal length compared to all the others. Some of you might be able to work out which one that is, but again I’m not going to tell you just yet.

Anyway, enjoy playing guess the lens. This isn’t intended to be an in depth test. But it’s interesting to compare lenses when you have access to them.¬† I’ll reveal which lens is which in a couple of weeks in the comments. You can click on each image to enlarge it.

Big thanks to everyone at O-Video Bucharest for making this happen.

  1. I like the flarey look of lens 2 (it`s also not so saturated and contrasty). And the shallow depth of field of lens 4 is also nice – it`s also not so red in the skin tones.

  2. I suggest that Lens 3 is Sony due to the larger depth of field. I have no clue what the other lenses are but I tend to say that lens 2 is Zeiss. Anyways it’s very impressive what a difference a lens can make in terms of color rendition! Not only overall but also for specific hues. Thanks for the comparison Alister, I’m really thrilled to see the reveal!
