    Evin, any plans to do more tests, for lenses that escaped from you the first round? I find what you did very insightful, especially considering opinions from all the contributors with their different backgrounds and ways to compare and measure differences between lenses.

    Right now I am torn between purchasing RPPs and Illumina S35s. Both seem good options for people on small budget ($27K for T1.3 18mm, 25mm, 35mm, 50mm, 85mm). But I absolutely NEED to know what you guys think about the Illumina lenses to make up my mind :-) what are their strengths and weaknesses??? Will they even cover Epic S35 @ FF?

    After speaking to the manufacturer of Illumina lenses I was told that the existing 5 lenses were designed and built with 31.8mm image circle and will not cover Epic's 34mm. He did not specify which lenses in the set exactly, but did say that they are planning to design and build 14mm and 135mm lenses to add to the set (around this time next year) and will keep in mind Epic's larger sensor.

    Area is naturally smaller than whole sensor. According to AbelCine 29.7mm so yes the lenses will work..

    @ 5K 16x9, yes, which is 4800 px horizontal
    but that is not as wide as it goes. at max rez it's 5120 horizontal so the circle is also wider

    I wish the Panchros could have been a part of this. Would love to see what all you guy think of them.

    Had a chance to test the Illumina S35 lenses with Epic and indeed 18mm does show slight vignetting at 5K FF. Other lenses in the set covered OK.

    that chart explains why 5D shooters constantly struggle with depth of field, while the 7D has become more popular.

    I thought I'd link this thread to the Portland Lens Test thread for more lens tests: http://reduser.net/forum/showthread....-LENS-SHOOTOUT
