Anyone using an AF confirmation adapter for this amazing lens? Thanks to Klaus and Photozone btw for the review.



I've heard of people using one but don't know what I need exactly or where to get one (I live in the UK unfortunately).

Well, you can get the Nikon version and use a Nikon-EOS adapter with AF chip. This will work in any case.

The Nikon version with af-adapter is absolutely a good solution and the lens can be used both with Canon and Nikon bodies. But one point is weather the af is really needed, because the hyperfocal distance of 14mm is so close. with f5.6 it is only 1,17m. So with f5.6 you only set the focus scale to 2m and shoot, and with f8 the distance can is smaller. This works well with this awesome lens for it´s price, under 300€.

I have read in DPreview pages that somebody has clued an af-chip to the mount in the same way as earlier was done with non af-adapters. Maybe it works too.

The big advantage of the focus confirmation chip is actually that it'll provide exif information to the camera (and to the raw and jpeg files IOW), which makes it a lot easier to identify when using all kinds of tools. I also understand that that way it'll work well with ETTL too.



However, as Klaus mentioned, I'd suggest to go for a Nikon version and use a Nikon -> EOS adapter with chip. No gluing required, or lining the chip up correctly for that matter, and generally you can have the adapter preprogrammed for your lens too.



Kind regards, Wim

Thanks very much for the replies. Sorry, I should have mentioned I already have the lens with Canon mount, I was unaware of the existence of an AF confirm chip at the time of buying.



Is it too late to get a compatible adapter? I was hoping all that was necessary was something like a T2 adapter but for Samyang. Does anyone know of a product and can provide a link? I doubt I'd do a good DIY job!



Thanks Pixee, for the additional information about hyperfocal distances. It is useful to bear in mind though I was considering the addition of AF confirmation light to be useful for wide open, close focus shots (more artistic stuff for want of a better descriptor). But it definitely is comforting to take into account for the remaining 90% of usage for sure.

It is too late indeed to get a compatible adapter, unless you can stil exchange the lens for one with another mount (Nikon I would suggest in that case, because if you ever decide to sell it, you have 60 % of the market covered with both Nikon and Canon <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />).



However, the chip should come with attaching instructions, and will be a lot cheaper than a good focus confirm adapter, i.e, one with chip already mounted. The chip by itself, latest generation, is probably about $25 or thereabouts, a good chipped adapter wil set you back at least $70, if not double that, plus of course shipping costs.



So, whatever the option, I do think that if you value a focus confirm chip, it is worth it to try attaching one yourself if you can't exchange the lens anymore, or don't have the budget to cater for the additional expense of a good, chipped adapter.



Kind regards, Wim

Thank you for going to the trouble of explaining further, Wim. I've had the lens for about a month now and though it's in the same 'as new' condition, I'm not in the same town I bought it and don't think I want to attempt to trade it in for the Nikon variant. It would be at another branch of the store I bought it from (London Camera Exchange), and I can just imagine what their general responses would be. A great big 'get lost' probably. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/unsure.gif' class='bbc_emoticon' alt='' />



Okay, so, if I try to track down this chip and adapter, or even a more expensive 'chipped adapter', are there any links that would help me identify what I need and where to best get them from? I really am still in the dark about all this, despite people's best efforts here to educate me more. Cheers. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />



Edit: I should add that I have searched but not really found anything that positively is what I need. And, re-reading your post, Wim, are these chipped adapters only available for Nikon and not Canon? So it's a dead end anyway if I stick with the Canon? Thanks. I'm a bit confused. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/blink.gif' class='bbc_emoticon' alt='' />

The reason to suggest a Nikon mount lens plus a Nikon->Canon adapter, is that the Nikon register distance of the lens mount (the lens mount to sensor distance so to speak), is longer than that of the Canon lens mount, therefore allowing for a piece of metal to be stuck in between lens and Canon lens mount and still allowing for infinity focus on a Canon body. If you'd add a mount adapter to a Canon mount lens for use on a Canon body, you'd effectively be using an extension tube, IWd, you can only focus at close distances, no longer at infinity. In short an adapter with a focus confirmation chip for a Canon mount lens is not available, as it defeats the object really.



This means your only solution now is to glue a chip to the lens mount yourself.

Wim, you are a legend. Thank you very much for the detailed (hopefully foolproof) information. I will be sure to let you know how I got on.



Thanks again for educating me, now I think I finally understand and shall go look at those links you've kindly provided.



You've saved me a helluva lot of running around websites and probably a couple of quid too.



If I ever get the lens chipped and manage to take some half decent pics with it, I shall dedicate them to you. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' /> <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />
