Illumina S35 Lenses – BEWARE!
This is an important review of the Illumina S35 lenses, please pass it on the community needs to know.
This is a test of a set of Illumina S35s that I purchased early this year (2012). I ended up sending them back for a refund. But due to a re-stocking fee I received only 90%. And because I also cancelled my order of the 135mm I ended up loosing, with shipping close to $5000 Australian dollars.
For me, the lenses didn’t perform. The 18mm & 25mm show severe edge distortion and softening – too much to be considered in the same league as Arri, Zeiss or Cooke. Distortion that wouldn’t smooth out until as far down as T5.6. Personally I don’t see the point in having a T1.3 rated lens that doesn’t perform until way past T4.
This is in fact the 2nd test I shot, to try and rule out the possibility of a back focus issue with the first test, let me assure you there was no back focus issues. The Red & the Alexa were supplied by a national camera rental company with a long and respectful history of serving the Australian film industry, they checked the back focus for me knowing the test that I was about to perform. Also, the lenses taped out to where they were supposed to ie. 5’6″ hit right on the lens mark. But the edges – well disappointing to say the least.
It was a sorry outcome for a set of lenses that I’d hoped so much for, I really wanted them to perform but I felt the edge distortion unacceptable, the build quality was suspect and the illumination was patchy.
I even had a lens tech at Panavision Australia look over the test and he said “I can see is that the centre is sharp and the edges are soft and there is a little distortion as well in your test. This is Field curvature, the inability of a lens to hold focus from centre to the edge of frame; distortion is the inability to reproduce image shapes accurately”. He then added “When compared to the Zeiss I can see the Zeiss has much better Field flatness”.
The lenses were sent back to the broker and the manufacture for testing, they re-tested and claimed the lenses looked good? I was amazed that they could make these claims. I shot tests on 3 different cameras and even cross checked them with a Zeiss Superspeed MkIII just to make sure I wasn’t going crazy – I wasn’t. The Red One, The Alexa and even the poor old Sony F3 revealed the incredibly poor performance of these lenses.
Ultimately I was pretty disappointed by the attitude of the owner of Lumatech, it was an expensive lesson for me to learn and unfortunately with a small amount like the amount I lost it’s hard for me to justify the expense of a lawyer, although I’ve discussed the situation with several, but the costs are prohibitive.
I would urge anyone thinking about these lenses to think again, I certainly won’t be buying anything from Lumatech ever again.
