Hi Everybody,
People need lenses. However, cine lenses are very expensive, and the price is not affordable for most people. So, still camera lenses are used by many people. There are some still camera lenses are modified and then sold in the market. And the price of the modified lenses usually becomes several times or even tens times of the original price. The is a ridiculous phenomenon. You have to know, the optics of rehousing lenses are still camera lenses. If it can only mount on cine camera, and without any improvement in function, then why not just mount the still camera lenses on your camera. (Nowadays, most digital camera can change the mount.)
So, what is the value of the rehousing lens?
The most valuable part is improved focusing structure if it is added on this lens. However, this is the hardest part to design, requires technique and costs most. But in the market, many rehousing lenses are focusing on modifying to PL mount, and maybe add iris ring and focus gears. If I have to spend thousands to buy these kinds of rehousing lenses, I’d rather to spend money on good mount systems for my camera.
Here I can give you some suggestions for choosing rehousing lenses:
- First, you have to pay attention to the quality of lens’ optics. You have to make sure that the quality is worthy for your money.
- Second, you need to choose one lens has very long and accurate focus rotation and scale. This is very important on video filming and I think everyone knows it.
- Third, you have to compare the original price with the rehousing price.
Anyway, we have to put our money on lenses with good optics, accurate function, instead of on PL mount or gears.
And now I would like to show you some of my works.
Many people know that I am doing rehousing as well. I really take too long time to do it, because I keep test and test and some lenses can not rehouse with same way. So I have to figure out different structures. Anyway, all of my test is just for one thing—to improve the accuracy of focus. These parts is some of my test parts, all of them are become wastes.
This lens was showed to you before, and it is under producing now. You can see the focus scale from the closest to the infinite is almost over 350 degree.
And this is another lens, rehousing from Nikon 14-24. For super-wide zoom lens, many people asked me about Tokina 11-16, and I said no, because the optics of this lens is not good enough, and would be horrible if use on EPIC 5KFF. Therefore, I’d rather to spend my time and money on Nikon 14-24, although it is not as wide.
Of course, you can find out that the focus structure of this lens is re-designed by me, so that we can get very long focus(sorry, I can`t show clear picture). People might be interested in the pricing, and I can promise that the price of it will be very reasonable.
And I will make rehousing ZA prime lens. But it won’t have PL mount. It will go with A-mount and EF mount. Now, I can hear so many people asked “why?”. If I want to make a fortune, I would choose a cheap lens and modify it to PL lens. But I am not a businessman, I am a cinematographer, I like very much how ZA(Zeiss for Sony) lens performs, more than ZF(Zeiss for Nikon). Unfortunately, ZA lens is not like Nikon lens, it doesn’t have enough space to modify to PL mount. So I choose A-mount (because it has cine-style lock) and EF mount (because it can be used for many cameras). It is not important for a lens to have what mount on it, the most important is the optics quality.
I can't abandon ZA lens optics. Even though it won't sale very well if it is not PL mount, I will still produce it.
Thanks for watching, it`s time to go back to work.
