SLR Magic quick test

 

How well do you know your lenses ?  If you want to test yourself, Watch this short video and see which lens family you like most.

You can choose between A, B or C, but which is the Panavision Primo, which is the Zeiss CP and which is the SLR Magic APO ?

I’ll reveal below in case you want to try and test your knowledge of lens characteristics.

In this short test I had a subject lit using a 12k Tungsten Maxi Ultrabounce wedge with a light grid. I actually added a daylight S60 syk panel to get the white balance to exactly 3200K.

I shot this using an Ursa Mini 4.6K shooting RAW. You can download the camera original files here. Be warned, they’re very large !

I applied a simple LUT form the show I’m shooting right now. Thanks to my crew who volunteered their time to help me with this and especially to Akeria for modeling for me.

This is my standard way of testing lenses, starting with a lens flare which I then pan across to show it moving through frame to a Kino tube which I find is a good way to test for CA, and for veiling flare. You can see the veiling flare change as the camera pans through it.

I SHOULD have frozen the pan instead of what I did, so it’s hard to gauge in this version how the CA is. I’m an idiot for forgetting this crucial step!

I then land on some skin tone, before racking to minimum focus for each lens and then through to infinity to check for focus breathing.

There’s some xmas lights there for looking at the Bokeh.

All shot at T2 1/2 and you do see some exposure variation between them but I’ve left that as is.

I’ve had the SLR Magic APOs in daily use now for a couple of months and I’ve been finding they match really well alongside the Primos that I’m shooting, much more so than the Zeiss CPs which tend to be very sharp and contrasty. The SLR MAGIC APOS are indeed sharp but they don’t pop as much as the zeiss, they’re more flattering to skin. Breathing is good and sometimes you can get an unusual flare which I wasn’t able to provoke here.

There was also a small bump in the focus on the SLR Magic 25mm as it went towards minimum. I haven’t noticed it in practice on set, but it’s there in this test. They have been remarkably well built though aside from this anomaly, and in daily use on high torque focus motors they’ve stood up perfectly well.

So how did you go ? Where you able to pick which lens family was which ?

Now for which is which ?

Lens family A is the SLR Magic APO Primes, the 25mm, the 50mm and the 85mm
Lens family B is the legendary Panavision Primo primes, the 27mm, the 50mm and the 75mm
Lens family B is the Zeiss CP2 primes, the 28mm, the 50mm and the 85mm.

    Nice little exercise JB. Happy to say that I picked the A, B or C lens families in the first setup.
    Hope all is good with you. Greg de M.
