We’re currently building and kitting out a studio, largely to be used for shooting products. We’re getting an Alexa, but are stumbling on our lens choice, mostly because the budget is not infinite. Our MUST HAVE primes are 35mm, and 50mm. We are looking at CP.2 super speeds – the cost is attractive, but more than that the speed is important – we often open up to f1.4 to knock the set background out of focus (rather than for exposure). I’m concerned about the performance of these lenses - I’ve not used them much - what are they like wide–open (T1.5)? We’re not looking at cinema projection here, TV or digital is where our shots will be seen, so I’m trying to be pragmatic. Am I worrying about nothing? Is there another line (other brands) of fast lenses that sits between Master Primes and CP.2 super speeds that I’m missing?
