EF-S Lens & compatability:

[Iguide]

Good evening all:


I have been doing a fair bit of research on just what cameras they are compatible with. I know that they will work with 1.6 sensors and not with full frame. What I have not figured out is are they compatible with the 1.3 sensors. I have not been able to find it addressed any where. It is most likely someplace very obvious and I have over looked it, or some other obvious place I have not thought of looking yet.


So does any one here have any idea if EF-S lens's work on cameras with the 1.3 sensor like the 1D Mrk IV? [:^)] Yea that is what I'm aiming for next. Well, if your gonna dream might as well dream high.


Thanks & Godspeed


Wayne

Short answer as far as I'm aware is no. EF-S lenses are only compatible with APS-C (1.6x) sensor cameras.

Unfortunately EF-S lenses are not compatible with APS-H sized sensor (1.3x FOVCF) cameras like the 1D Mark IV. You'll have to invest in EF-mount lenses if you purchase a 1D Mark IV.

Excluding the 10D, where Canon had not yet come up with the idea of EF-S lenses.

Maybe not in the USA, but in Germany:

(no EF-S lenses on the 10D, see http://www.canon.de/For_Home/Product_Finder/Cameras/Digital_SLR/EOS_10D/index.asp?specs=1 ("http://www.canon.de/For_Home/Product_Finder/Cameras/Digital_SLR/EOS_10D/index.asp?specs=1))

Hi cfnz, alexniedra, DavidEccleston, Yves, neuroanatomist &amp; Kayaker72:


Thank you all very much for that information. Could you please point me in the direction of where that information is stated. I'm kinda in the middle of a debate with my buddy on this and he refuses to believe that they are only compatible with only the APS-C and not the APS-H. As for me I only have one EF-S lens the 17-55 f2.8 IS USM, so it is not like I need to replace all of my lens's.





Thanks Again &amp; Godspeed

That's exactly what David is (correctly) stating - EF-S lenses do not mount on the 10D. They do mount on all other Canon APS-C bodies (7D, 20D and up, and all the digital Rebels).

Hi Wayne,


Check the Compatible Lenses:Canon EF." Compare that to the same section of the specs for an APS-C camera, e.g. the 60D specs (http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_1d_mark_iv#Specifications]1DIV specs: "<span class="bold_text): "<span class="bold_text"]Compatible Lenses:Canon EF lenses (including EF-S lenses)."


Hope that settles the debate...


As a side note, if you mount a Mk II extension tube (EF 12mm Extension Tube II orEF 25mm Extension Tube II) to an APS-H body (or a full frame body, for that matter), you can then mount an EF-S lens to the extension tube. Of course, you'll lose the ability to focus to infinity, and get a lot of vignetting, so you wouldn't want to do that. But, technically, you can make an EF-S lens compatible (sort of) with an APS-H or FF body that way (Bryan did that in his review of the EF-S 17-55mm ("http://www.The-Digital-Picture.com/Reviews/Canon-EF-S-17-55mm-f-2.8-IS-USM-Lens-Review.aspx), down near the bottom of the review).

[Kayaker72]

Another source: http://en.wikipedia.org/wiki/EF-S ("http://en.wikipedia.org/wiki/EF-S)


Also, almost all of Bryan's EF-S reviews have some statment such as " Before reading any farther, you need to be aware that all Canon EOS cameras can accept EF lenses but only Canon EF-S compatible bodies (1.6x FOVCF ("http://community.the-digital-picture.com/Canon-Lenses/Field-of-View-Crop-Factor.aspx) only) can accept EF-S lenses. "


Finally, canon's website talks about it, most specifically the compatible camera bodies are listed on page 2 of the instruction manual for each EF-S lens . I don't see any APS-H cameras on that list. Here is the link to the EF-S 15-85:

Easy answer: look at a picture of the body with no lens mounted.


If you see a white square, it'll take EF-S. If you only see a red dot, EF only.

I think in order to make the lens a little cheaper, they needed more realestate to work with (length). Knowing the 1.6 crop sensor is smaller, they snuckpart of the lens inside the camera. At least that's how I understood it. And the 1.3 is just big enough to hit. Like Peety said, no white square on the camera, no ef-s compatibility.

I think what makes the lens cheaper is that an EF-S lens only needs to produce an image circle large enough to cover the smaller APS-C sensor (26.7mm diameter circle vs. the 43.3mm needed for FF). The smaller image circle means the optical elements can be correspondingly smaller in diameter (= cheaper), and the mechanical elements needed to move those lighter optical elements can be less robust (= cheaper), etc. Even so, 'cheaper' is relative, and you can see that with a lens like the EF-S 17-55mm - it's fast aperture and multiple aspherical and ultra-low dispersion elements give it L-level lens optical performance, and it has the L-level price tag to go with that. Still, the closest FF equivalent would be the mythical EF 24-70mm f/2.8L IS - and if that lens is ever released it will probably cost nearly double with the EF-S 17-55mm costs.


Since the lens mount to sensor distance must be the same as FF for compatibility with EF lenses, but the 1.6x sensor requires a smaller mirror, Canon took advantage of that slight increase in space within the mirror box to design lenses that protrude a bit further into the body. The short back focus also facilitates the design of wide angle lenses.

You "can" make an EF-S work with a 1D series body. The trick is you have to remove the rear bezel (black plastic), which can be done by hand after zooming all the way out with the lens. Below is a link with the write up on the 10-22.

My link is from the official technical data sheet, found at canon.de, the German Canon hp. AndI can't believe in differences between Canon Europe and Canon USA...so no EF-S lenses on the 10D (or any other 1.3x crop sensor cameras).


The technical problem is the mirror, not the distance between lens and sensor. You can remove the mirror (but do You want to try it???), but then You have no more viewfinder...


So the only right decision is: 10DOR EF-S lenses!

Hi Yves:


Understood about the link. The problem is that for many of us it is written in German. Good for you not for me.

Sure, that's a problem. But it is better to get official informations in a foreign language then to get no informations...[^o)]


And, by the way, sometimes I have some trouble to find out what is the meaning of the posts here...but I still do my best![;)]


Jan's link worked fine, I hope.

You're not the only one, trust me [;)] I have to read some of the technical posts 3 times before I totally know what they say [:P]
