Tamron 17-50 2.8 on GH1?

If I understand well, in order to be able to control aperture with the jinfinance adaptor you have to purchase a Nikon (and not Canon) mount of the lens
and the lens must have an aperture ring. Do all Nikon mount Tamrons have an aperture ring?
 
Kostas, yes you need to get the Nikon version but no you cannot control the aperture from the lens. This lens does NOT include an aperture ring. You need to get a Nikon lens to M43 adapter that allows you to control the iris FROM THE ADAPTER...such as the previously mentioned Jinfinance model or from Novoflex or Ciecio7.

Note that some Nikon adapters do not allow you to control aperture.

Thanks for clearing this up. I guess you need the Nikon version of the lens because the corresponding canon to micro 4/3 adapter doesn't have the possibility to control the iris. True?
If one had both the 550d and the gh1 the best solution would be the canon version of the lens though, I think.

Actually the Canon version of the lens is not even an option for the GH1. It would work fine on the 550d of course, but on the GH1, you would be stuck at f/32 all the time and wouldn't be able to change it.

I thought that if you set the aperture of the lens on the canon body, then put the lens on the gh1 body the aperture setting wouldn't change. Of course this is a bit of a hassle, but I am just wondering if it works.

Well yes that works, but boy is it a pain, and I don't personally consider that way of working to be acceptable or usable, but I guess if that was your only choice then I guess you'd just have to do it that way :-|
 
Has anyone seen this... bit.ly/c8IKRG

I was looking into a getting a zoom lens of similar focal length and was looking into the Tamron, of course cause of the price, but then I saw this...

I assume there would be no way to control aperture on something like this, is there an adapter for a lens like this that can control aperture?

While there are m43 adapters that provide crude control over a Nikon G ("gelded") lens, there are many more Nikon-mount lens available that have built-in aperture rings and manual focus rings (including most autofocus lens). The other type of Nikon lens to avoid are DX lens, which are designed for APS-C sensors instead of full-frame sensors. While the G and DX lens can be made to work on a GH1, you can have far better quality and usability with a traditional Nikon lens.

Yes there are lots of Nikkors, but very few that are reasonably priced AND wide angle. Hence this discussion.
There is nothing wrong with Nikon DX lenses for GH1 usage and there is no reason to avoid them, because the GH1 isn't a full-frame camera anyway (nor an APS camera).
Yes far better usability is true, but many of the DX lenses offer very high quality.
 
Yes, Nikon DX lens are high quality. However, the image quality of wide angle lens tends to fall off near the outside edge of the lens, which on a DX lens is not far from the four thirds sensor's edges. With a full-frame 35mm lens, the image picked up by the sensor comes from the middle of the lens, where image quality is the highest.
 
Unless you plan to use the lenses on a full frame as well, it seems like DX Nikons make perfect sense for the GH1. For instance the Tokina 11-16 f2.8 has received many accolades on this board and elsewhere for it's amazing IQ. Where else can you find a fast, wide lens that looks good? And for a mere $600 to boot.
 
Hello i just orderd this adapter:

http://cgi.ebay.co.uk/Nikon-G-AF-S-...ns_caps_hoods_adaptors_ET&hash=item5d282dfe76

My plan is to use this adapter with tamron 28-70 i havent got the adapter yet but i now feel very unshure about this adapter, how will i do to change the apenture? with a ring on the adapter? culd someone please help me out?

Is there any better adapter out there that will work much better? (dont really care about the price, just want it to work perfect)

or is there any better lens (2,8 zoom all the way) that works better with gh1?
 
Help? Is there verison that don't work?

Help? Is there verison that don't work?

Crucial to get the Tamron 17-50 to work on a GH1 is that the aperture can be controlled by the adapter.

Now, today I tried to buy a Nikon-version om the lens from Cyberphoto in Sweden and they did not beleive it would work. They needed to test it before. Ok, that is fair enough. Don't promise things you don't know anyting about.

But is it possible that there is different versions of the lens and there some can't have the aperture control through an adapter?

I have a Pentax mount version of the Tamron 17-50mm, have I got any chance at all of using this on a GH1? With aperture control?!
 
@JimNastics, I don't think you can use on the GH1 because there is no way to control aperture. Unless there is a Pentax adapter that controls it. I've never heard of such a beast.

@leif ivan, the Nikon version CAN be controlled through an adapter but it must be the correct type of adapter. On eBay, they usually say things like "For 'G" lenses". If you're not sure, check with the seller. There are two versions of the Tamron 17-50, but the only apparent difference is one has what they call Vibration Compensation (VC). I would think either will work the same with an adapter, but I think a Nikon body would be required to get any VC.

hi, everybody,

I just wonder, what Tamron you are talking about, because there are two versions (400$ and 600$):
http://www.bhphotovideo.com/c/product/550954-REG/Tamron_AF016NII_700_17_50mm_f_2_8_XR_Di_II.html
http://www.bhphotovideo.com/c/product/652137-USA/Tamron_AFB005NII700_SP_AF_17_50mm_f_2_8.html

is it the second (more expensive) version everyone like?

The one with VC is the one that is a bit blurier.
The original (XR DI II) without VC has been noted to be very sharp -- coming close to the sharpness achieved on the Canon 10-22 (which is practically double the price)
