Lens L - Is - Dc

What do these Letters and others after the Lens name mean :confused:

Any feed back from the gurus would be appreciated

From the new kid on the block.... :)

L stands for kicks ass.(i really don't know but it's basically canon's top of the line lenses)

IS stands kicks even more ass.(image stabilization)

dunno about dc(digital crop maybe?)

[forno]

L is for Luxury

DC ?????

In case that wasn't all clear:

L - this is the top of the line lenses by Canon. They have the highest quality optics and are the most expensive.

IS - Image Stabilization is in the lens for Canons, some camera makers have implemented IS in the camera body. This adds weight, cost, and complexity to the lens, but can be a hugely important feature especially on long lenses. It allows you to shoot at a slower shutter speed then you would normally be able to use without a tripod.

DC - Not sure what this is. For the crop lenses (lenses that only work on the non-full frame cameras) they are designated EF-S. Could you mean DO? That stands for Diffractive Optics, which reduces size and boosts image quality.

I'm going to go out on a limb here, doesn't DC mean something like Digital Camera (SLR).

I mean, someone was telling me, if you notice where the lens connects to the body, you line up the red dot or white square. The red dot is for SLR camera and white square is for Digital SLR, of course, can be used either SLR or DSLR but the white square is optimized for digital SLR?

I think I just confused myself lol.

DC usually means "digital crop" meaning it won't work on full frame (regular 35mm) cameras.

DI II also means that, as does EF-S.

L isn't always the beat quality but it means the best build quality. The 17-55 EF-S is a very high quality optic, better then the 17-40 "L" but built like a hunk of crap and crop bodies only so it's not an L.

Best explanation ever :)

Can you imagine how many "arses" a L IS lens would kick?

I think DC stands for Digital Crop, it's a Sigma designation:
"DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction."

Is there a web page which describes all the lens acronyms ? :rolleyes:

Or a thread on here, Ive read the Lens Reveiw pages and very good it is.

Is there a canon page like the sigma?

[coldrain]

I do not think there are sites that tell all of the acronyms and such...
But they are not all that complicated either.

EF = Canon's auto focus lens range for the Canon EOS system
EF-S = Canon's auto focus lens raneg specifically designed for APS-C crop sensors.

APS-C lens designations from other manucaturers:
Sigma: DC
Tamron: Di II
Tokina: DX
Nikon: DX
Pentax: DA

Sigma and Tamron use DG and Di respectivily to show they adapted the coatings for digital cameras, for full frame lenses. DC and Di II are for the APS-C lenses.

Image stabilization:
Canon : IS
Nikon: VR
Sigma: OS

Silent ring type motors in lenses:
Canon: USM
Nikon: AF-S
Sigma: HSM
Minolta: SSM
Pentax: I forgot.

Nikon uses ED to say they use certain types of glass in lenses.
D and G to differentiate lenses with aperture ring and without, for modern AF SLRs.
Canon uses L for their top build quality lenses, "Luxury".
Tamron uses SP for the lenses they find to be their best lenses.
Sigma uses EX for their better built lenses.

APO is used to say they used special measures to make sure all 3 base light colours get bent in the same way, so the images of all 3 colours have the same focal point. Apochromatic.

Asph. I used to tell a lens is corrected, to show a flat image instead of a curved one (like a fisheye lens).

Hmmm.. what else...

DO is used by Canon to tell special optical elements are used that allow a lens to be built a lot more compact.

I think that makes for quite a complete list for now.

Coldrain, thanks for the write up

Dave Metsky & dmuller thanks for the links I will have a good look at those sites when i have more time :)

[nutsnbolts]

Yes that is a great write up.
