What's the lense standard for cooke s4/i

[Ahmed Al Dhahyan]

Hi guys, I try to know normal focal length which is nice for wide angle and close up etc..   And what do you think about 21mm is it perfect for that ?. I'm looking forward your recommendation 

Thanks a lot

I generally find that 21mm is as wide as you can go (in terms of focal length) without getting problematic perspective distortion on close-ups.

So yes, I'd say it's the perfect choice for what you describe. ?

Thanks mark, I was thinking about 18mm but I feel don't help me what I need, which is better for just long shot
