18-55mm on Full Frame?

[marco_de_biasi]

<p>Hi there,</p>

<p>I've a 18-55mm lens (http://is.gd/fJ80km) and I use it on my 7D.<br>

I'm wondering if it's gonna work on a Full Frame camera and if so, what issue I can have, i.e. vignetting, ca, etc....</p>

<p>That lens is an EF-S lens that will NOT mount on a full-frame camera.</p>

[marco_de_biasi]

<p>oh :/<br>

thank you Charles!</p>

<p>EF-s lenses will not mount on full frame, physically there is a ring that prevents that. Further to that EF-s lenses protrude back further than EF lenses. If you search the archives/internet you will find that the ring can be removed so you can mount the lens on a FF body, with the risk that the mirror hits the rear of the lens. You can try it at your own risk.<br>

You could try using an extension tube, it will give you macro capabilities and you'll loose infinity focus. In my opinion it's not worth it bur YMMV.</p>

<p>Thanks Jos,</p>

<p>I was planning to use it on a FF mirrorless though...</p>

<p>And use that terrible MF ring to manually focus?</p>

good point!<br>

I totally forgot about that, I'm using only manual and I've that 18-55 sitting in my bag.<br>

Time to sell it! :)</p>

<p>Like a Sony Alpha 7? Apart from severe vignetting that ought to work, assuming your adapter accepts EF-S lenses.</p>

<p>Whatever kind of sensor or film, an EF-S lens will only cover roughly a 24mm diameter field.<br>

The regular lenses (EF) will normally cover a 36mm diameter field (the maximum dimension of "full-frame"), although some special lenses or adapted medium or larger format lenses will of course cover whatever they are made to cover (6 cm, for example).</p>

<p>Presumably you mean a minimum of 26.8mm (EF-S) & 43.3mm (EF) respectively?</p>

<p>Many zooms also increase or decrease their image projection area dramatically as they zoom in or out. That said, I would be pretty surprised by an EF-S lens that covered the full sensor of a full frame camera - unless it was on an extension tube.</p>

[JDMvW]

<p>Marcus, of course you are right. It's the diagonal diameter, not the x by y distance.</p>
