  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Super Zoom Lenses?

The Hawk 150-450T2.8 is Spherical. And just to second what Florian said: A very nice lens! You can get the lens in an Anamorphic version too, but then it's a 300-900T4.
 
There's also the Elite 120-520 T3, available for rent from Slow Motion in LA. We stuck it on a Phantom HD for kicks and shot surfers about a mile away. What an amazing monster lens. It becomes a 170-730 T4 with the 1.4x extender and a 240-1040 T5.6 with the 2x extender. It's also several feet long, possibly the largest lens I've ever mounted on a camera. Makes the Optimo 12x look like a prime!
 
My Sony Z1u camera says 12x (32.5-390mm).

So if I am looking at a lense on a 2/3" sensor...say a Panasonic HPX 3000, that has say 540mm and I put a 2x extender on it..that would give me 1080mm?

And if so, would that then be approximately 3 times closer at maximum zoom as my Z1u at maximum zoom?

I am trying to compare about how much closer something looks like compared to my current setup?

Reaching out at 4K

Reaching out at 4K

The range of sensor sizes: 1/3", 2/3" and Super35 (roughly 1.33") being discussed here create a far greater field of view differential at specific focal lengths as expressed in millimeters than one might expect. This thread was started by a poster looking for "super" zoom options with a lot of reach and lot of range who cited "box" lenses used for sports and concerts.

If 2K resolution is sufficient for your project then a B4 adapter, bomber tripod head (the Vinten 75 is a work of art) with one of the many field lenses offered by Canon or Fujinon is your answer. If you require 4K rez then I would suggest you research and if possible rent several of the lenses cited in this thread to see if they meet your needs.

Will the lens manufacturers recognize that the RedOne and other next generation electronic cameras are impacting the level of demand for "super" zoom lenses for anything but 2/3" 3CCD cameras anytime soon? I recently took a booking to shoot a multi-RedOne concert and will likely spec the big Optimo for the back of the house position. Its a great lens but unless I can get within 160 feet of the stage the 290mm end of the bottle will leave me wishing for more.

Concerts, and to a lesser degree Sports, should make compelling 4K programs - particularly for theatrical showings on the Sony 4K SXRD. Now, who's going to step up and lay out the coin to develop lenses designed specifically for this use? I am certainly not an optics expert but from what I do know the requirements of resolving 4K at high magnification and maintaining precise focus over a large range of focal lengths with multi-element design is asking a great deal of lens designers and builders.
 
I started this post! I appreciate the info. I still would like to know some general comparison (so I know if I need 300mm, 600mm, 1200mm or more...these are huge price differences) between what my Sony Z1u (1/3" sensor) shoots at maximum zoom vs. what a 2/3" sensor would shoot as some specific mm length...then I can figure out how much zoom I need.

And my final output is 1080p, so I don't need to go beyond that...I know I can shoot higher and downsize and get some digital no loss zoom there as well if shooting at 2K, 3K or 4K.

If I did red which I know is a 35mm sensor, yes, I am wondering for that too, what would be the equivalent zoom I would need roughly so I am not wanting more.

Again all comparisons to my Sony Z1u make sense to me as that is what I shoot with today. Anything else and I don't quite know what that really means.
