Hi, i just wondering if i can use any lens with the 100a, i just need a adapter ring, its that true,

i cant afford the 1.6 Century optics,

any solutions

Thanks
 
Do you mean a lens adapter (like a telephoto attachment) or an actual lens, like a DSLR lens? I assume you mean an adapter. You can attach one, but, yes you do need an adapter ring to convert to the correct thread diameter. However, you aren't going to want to mount anything smaller than, I'd say probably 67mm because eventually, the smaller the converted diameter, it will begin to vignette and look unprofessional.
If on the other hand you do indeed want to attach a DSLR lens or movie lens, you will need what's known as a 35mm adapter which mounts in front of the camera. They range from $1000 to well over $5000.
 
both those lenses are CRAP
save the money and get the real thing.
don't cheap out in quality glass or you'll regret it when you are editing it.

Also, a 35MM adapter will cost you more at the end than the Century Optics lens.

Thanks Alejo, i got it

but, sorry im newbie, i still not understand why i need a 35mm adapter if the lens have the 72mm diameter
 
The 35mm adapter is if you are mounting a lens that is either a movie lens or SLR lens. I just wasn't sure what you meant at first. However, both of those lenses will work on the camera, but they are indeed crap. I also think you should save up for one by Century Optics, but if you need one and can't afford it, then you could get one of those. I'd say go with the fuji lens, as they make good broadcast camera lenses. Digi-tech is a knockoff brand.
 
35MM lense doens;t mean 355mm THREAD.
is just like the focus length of it.
just like a 50mm or a 135mm (i would love to see a 135mm thread :giggles:)
anyways,

do research and learn it.
if the 35mm is something you want, there are websites that teach you how to make it yourself....
even if you won't be DIY'ing it , still read thru the tutorials as they explain everything there is to know about adapters.
 
thanks to both, i do a research and i quite understand what you say. i found a century optics used for 130, i think it is good price dont you think

another one, it is really necesary to use filters like UV and polarized, if is so, whis is good enough

whats the diference betwen polarized and built in ND filters

Thanks

ok, you use filters when needed!
remember, every filter you add bumps up the f stop, meaning less light
polarized/nd filters are used mostly outdoors under sunlight.
 
thanks again Alejo, sorry my isistence, but i dont understand if there is a diference using a polarized filter or the built in ND filter
 
a polarizer filter is different from an ND filter in that polarizer filters are usually used to kill certain reflections from shiny surfaces while the ND filter will cut down the amount of light to allow you to run slower shutter speeds without blowing out your highlights.

at least that the way i see it.

here are two examples:

Polarizer Filter.

part of the image darkened by using a 3/f stop ND filter


neutral-density-filter4.jpg
a picture taken with a ND filter
as you can see, the ND filter allows you to run slower shutter speeds while maintaining the same /f stop so your depth of field doesn't change and movement is blurred with the slower shutter speed.

i hope this helps
