This means your camera would be unable to use autofocus and the viewfinder would be very dim when trying to manually focus. You might be able to use magnified Live View to manually focus. All of the flaws of the lens are magnified along with the image it projects.

Sharpness would suffer. You also would give up a little contrast. Chromatic aberration purple fringing would likely be increased. If the extender in question has a white square alignment mark on the lens-side bayonet, then it will accept the EF-S lens. If it has only the red circle, then it won't but if there is physical clearance it ought to work optically if you defeat the keying on the mount.

Don't bother with teleconverters with the EF-S mm, even if you find one that works with crop frame lenses.

You'll be wasting your money if you bought one. I think I already know the answer to this question but as it is so much cheaper I'll ask anyway,. What about using a spotting scope and adapter? Would the image quality be so poor that it is not worth the trouble? Likely you will be returning it. TC do degrade image quality but the best e. Found this site that lists teleconverters available and compatibility. I'm still not sure looking at this site which, if any are compatible with EF-S.

I love my and if I could reach just a little further it'd be perfect, but no TC works with it apparently. Not sure if that's changed since So now I'm stuck trying to save a thousand bucks for a decent mm, or scrapping probably my favorite lens in favor of a mm that accepts TC's. Anyway, I was able to use a spotting scope with adapter, just a few days ago. The image quality is simply too poor.

There's bad CA and vignetting which I can deal with but something about the scope doesn't allow focusing beyond a certain level of sharpness, no matter how carefully you fiddle with the dials.

I ended up returning it. I was so excited mm for just bucks??? Sample image if anyone is curious. This is postprocessed as much as I could in the Raw editor, and I adjusted the contrast etc. Could just be this particular scope sucks, but other spotting scopes do ok.

But I suspect that you mostly just get what you pay for, there's no free mm lunch. Crops from my were much better than any shot I got from the spotting scope. While I'm not great at estimate yardage this was probably not more than feet. The teleconverter made by Fotodiox will work with the EF-S lenses. It has the recessed area that needed to clear the lens.

Thanks for letting us know about this. Hm, I don't read it that way. Someone said it will work with EF-S "mounts". I can only find people saying their EF-S lenses won't fit in the reviews and questions on the page linked above. Is that where you're looking? Please quote the text and links, thanks. I can tell you as a certainty that the Tamron 1. Other TC's, I don't know.
