Zoom Lens Questions?
 

I am using a JVC gy-hd100 and I am looking for a zoom lens to replace the standard 16x.
My thoughts are on the Sigma 120-300 f2.8, Sigma 100-300 f4, or the Sigma 70-200 f2.8.
I am confused, reading various threads. There is talk about these lenses not having an aperature ring, is this correct. If so what are my options? I will be shooting wildlife.

Moved from UWOL to ProHD.

Jason,

Go for nikons. I have a 80-200 f2.8 and is amazing in shooting nature. A guy here, Eric Gulbransen uses the same plus a 80-300 and has done great nature shots with it. Try to do a search on him here and you can view his samples.

By the way, i guess by now you know you need a third party adapter to use these. Which one are you using? I have the Zoerk.

Thanks Ted, I may have to look into a nikon lens. I had heard great things about the Sigma lens and I know Per Johan is using a 70-200 Sigma with great results that I have seen. I havent purchased the adapter yet, but I am going to get the MTF.

I have several Sigmas in my arsenal too Jason. I use them for my wide shots.
They are good and cheaper, and the models i use have aperture rings.

You may want to consider getting used nikons on keh.com if you're on a budget.

Some of the newer lenses that Nikon and Sigma brought out do not have aperture rings so cannot be used. But, there are older models out there that do. I have the new Sigma 70-200 which is of similar quality to the Nikon but would have to buy an older lens to use with a video cam. The Nikon 80-200 is a really good model.

This is correct. Most of the newer digital lenses don't have aperture rings (the camera itself has the aperture), and newer versions are sometimes denoted with a "G" (if they're Nikkor).

On a side note, how are you connecting the lens to the camera? What adapter?

Is the Nikon 80-200 still sharp when used with a x1.4 extender?

Dave,

Do you mean putting an extender on the 80-200 then onto the mtf/zoerk then onto the jvc? or in general terms as when its used on a dslr?
Because when you put the nikon, any slr lens for that matter, onto the jvc via mtf/zoerk adapter it effectively increases its focal length by, uh if my memory is right, about 8x.

Hi guys

I have a number of Canon DSLR lenses.

Does anyone make adapters to run these on the JVCs?

Scott, I plan on using the MTF adapter, which gives apox. 7.2 magnification

thanks for all the help, after doing a bit more research I am now in search of some older lenses. Does anyone know if the Sigma 120-300 f2.8 is a new lens and there is no older option for this one??

Hi Jason,

I'm wondering if I have the calculation of that adapter MTF correct. If the magnification is 7.2x then the lens would effectively be a 864-2160mm? Am I missing something?

Also, how much did that adapter run you?

Hi Scott, your calculations are correct, I have not purchased yet, but it is in the works. Runs just over $400 shipped from Mike Tappa of MTF Services in London. I am currently looking for a lens or two then will purchase the adapter. There are also a couple other options out there, another is from a company called Zoerk JVC GY-HD200 Lens adapter comparison - Zoerk VS MTF

Can you explain the reason for such a huge zoom? I don't understand how that adapter can be useable. Is it for documentary type things? For narrative I can't see using anything with that high a focal length, even 200mm (normal, no magnification) would seem high to me.
