i just saw this in DPR's Nikon D3 review that the new FF camera supports Nikons DX lenses - for crop sensor as well as the FX lens.Come on Canon you should make the new 5D MkII or 6D which should be able to handle my EF-S 17-55 IS lens.

Would you be satisfied with a $5000 5MP camera?If you go full-frame, sell the 17-55/2.8IS for the 24-70/2.8L or 24-105/4L IS.

It's not exactly a secret that EF-S doesn't work with full size sensors/mirrors.Anders @http://www.aobild.com*

sigma DC lenses and tamron Di lenses will work on your full frame 5D... but there will be serious vignetting around the outside borders.the nikon full frame camera lets you mount a DX lens, but tehre will be serious vignetting, so saying that they are "compatible" is a little misleading...because they aren't. the DX lenses don't provide a large enough image circle for the full frame camera.

You get light falloff wide open but the Sigmas mount just fine on FF cameras.I agree its better to sell off the 1.6x lenses if you get a FF camera. ' -- ---------------------------------------------------------------------------- - http://www.pbase.com/jackcnd/british_tornados -

These people are missing the point; when you mount a DX lens on a Nikon FF sensor, the image size is reduced just the same as on a cropped sensor so the lens is just as usable on FF as it is on the copped sensor camera. A huge edge in compatibility for Nikon.

That's wasting money big time.EF-S is only for wide angle. If there's one situation where you don't want to crop, it's wide angle.

Just add an EF 12 II tube between the EF-S lens and the body.

Maybe Nikon have thought that aps-c on a FF sensor acceptable, that it will allow people to use their aps-c lens. They have only just accepted that FF is the way to go. At least Canon have a FF camera at a reasonable price. No disrespect but evrybody was happy the way things were, Nikon shows one FF camera, pro spec, expensive and will probably be elusive like their 18-200 and we get all these weird threads. Nikons new releases do not make any other camera worse, just differnt for the moment. Relax use what you have, ....... Enjoy...............

framemanwrote:Nikons new releases do not make any other camera worse, just differnt for the moment. Relax use what you have, .......QFT.Everyone is going crazy about Nikon's new releases. If your equipment is satisfactory for your needs, then it shouldn't matter much if the manufacturer comes out with something better, and it shouldn't matter any more if some other manufacturer comes out with something you think is even better than that. Brand loyalists act like they've signed a contract to use Canon gear, and that Canon is contractually obliged to produce the best gear. If you aren't happy with your camera, buy a new one. If you want to switch to the Nikon system, you can sell your lenses for nearly as much as you paid for them (unless they're in poor condition). I think a lot of people on this forum want to have "the best" equipment solely for satisfaction of having it.That said, there's not much debating that Nikon has been better than Canon about backward compatibility. Canon designed an autofocus system that was totally incompatible with the old manual focus lenses. Nikon made their system compatible with the old lenses as well (although their newer entry-level cameras have removed this backward compatibility). It could be argued that Canon's design choice (with each lens having its own internal focus motor) was justifiable for the much better AF speed it provided, at least initially. But, it appears that the design of the EF-S mount was intentionally made to be incompatible with the early digital bodies. A user perfectly happy with a 10D had to get a new 20D to use the 10-22mm lens, which was at the time the only ultra wide-angle option for APS-C sensors. Canon could have made these lenses to be compatible with the standard EF mount. We know this because the third-party manufacturers have done exactly that.

Is quite simple; if the lens meets your needs on a crop camera it will also do the same on a FF model. Thats called versatility.

Maybe you have a 1.5x and FF camera. If you find a DX lens useful on the 1.5x, the beauty is its interchangeable on the FF one. Is that a bad thing?? If it meets your needs on the 1.5x camera, it will do the same on the FF one. If it doesn't, sell it.

randy jkwrote:Is quite simple; if the lens meets your needs on a crop camera it will also do the same on a FF model. Thats called versatility.Except the crop sensors usually have way more pixels in that cropped portion. A 5D cropped to 1.6-crop has 5MP. Even a 1DsII cropped to 1.6-crop has only 6.5MP. If you buy a 1Ds for the pixel count, it makes little sense to through away 60% of those pixels.

I'm pretty sure there will be someone who likes it, or why else Canon created the sRAW?

lets do a reality check first:DX mounted in Nikon FF (pardon: FX) gives 5Mpix. a 5000$ body producing 5Mpix image with a lens costing up to 2000$, right?I honestly, and I really mean it: honestly, don't see many people using this, other than if they already have DX lens and must use them for some reason.this option is pure markieting gimmick. just the way aroud to not say Nikon pros they've been f*d about DX and can now stick their pricey DX lenses into their...Canon had FF for a while and its users had always been aware a budget FF comes. hence, most photographers had the option to buy EF-S or EF depending on their current and future needs. those who opt/opted for future FF simply stay away from EF-S. why should they now be given a gimmick oportunity to use EF-S in FF body?honestly... Nikon decision is just to don't admit gross misinformation and bad handling of their pros. the really isn't much use of this option. you don't buy $5k camera to use 5Mpix. those who do are simply cheating themselves they made good investment in DX glass. not that DX glass is bad because they have some excellent lens in this pack. but ultimately - for FF you buy FF lens. period.shan_lwrote:i just saw this in DPR's Nikon D3 review that the new FF camera supports Nikons DX lenses - for crop sensor as well as the FX lens.Come on Canon you should make the new 5D MkII or 6D which should be able to handle my EF-S 17-55 IS lens.

randy jkwrote:If it meets your needs on the 1.5x camera, it will do the same on the FF one.Because of the amount of unusable pixels it will not do. Period... And EF-S is physically incompatible because they use a smaller registration distance and in consequence the lens back element will interfer with the mirror on a FF body.In the Canon system everybody knew that when buying EF-S a use of such a lens on a FF or 1.3x crop body was neither intended nor possible.
