The Next Question = For use the EF to EF-M Adaptor, Yes, We can use both EF and EF-S mount to this Adaptor and shoot with EOS-M----How can We use EF-S with the same space distant from the back of EF-S lens to the APS-C sensor, and work---BUT Can not mount EF-S Lens on Full Frame Sensor Canon EOS Cameras----In the reverse, We can use all EF Lenses on the SOS Body / Small sensor like 7 D .EF-S has an identical 44 mm flange distance to EF. However, EF-S lenses are specifically designed to create an imaging circle which is not big enough for a 36x24 mm frame. In a bid to prevent strong mechanical vignetting, EF-S lenses have a plastic bung at the back preventing mounting on an EF mount body. This has a second advantage - these lenses can be designed to poke deeper into the body into the area where the larger FF mirror would otherwise clash, allowing some wide angle EF-S lenses to be slightly less retrofocus than the same focal length FF lens would be.
??, May be, Canon try to trick us, Not let us use the cheap FE-S Lens on the high cost FF Cameras .
how do these charts compare to canon charts?
Hmmm! ... can you repeat the question please!
Just to confuse the issue - you may find that a polarising filter will do a better job of cutting through the haze.
Have a look here for an example:
You missed a chance to save money and get a Crop Camera like the 70D instead of the 300mm f4.A 70-200/2.8 on a crop body is still a 70-200/2.8. However, if you want to look at it in 35mm terms, equivalence isn't just something restricted to focal length - it effects equivalent aperture and ISO too. The only part which needs no equivalence when comparing different sensor sizes is shutter speed.
Together with the 70-200mm 2.8 II you'd have the same amount of reach, you'd be more flexible and have one f-stop more speed.
How about distortion? Had any trouble with that? 24-105 is great all-rounder but distortion at 100 complimented by softness is just killing me. I love it most at 35-65(it's straight range).
It is really important for me that the lens is super straight, super sharp and the colors to be right.
im confused the caon 100 mm macro is not compatible with dual pixel af but the 55-250 and 18-55 kit lenses are while the 100 mm macro is more then2 times faster focus wise?
im sure theres more to this as it makes no sense at all.
All- thank you for your replies.The 70-300/4-5.6 IS USM was released in the latter half of 2005, 2 years after the 300D was released. 6 months prior to the lenses introduction, the 300D was discontinued. Are you sure it's not a 75-300 you've currently got?
Jim, Im quite certain I bought my Canon 300 (rebel) in 2003 or 2004... I was taking pics of my kids at sports events and the like with it (checking file folders). It is 70-300mm EF w/ image stabilization, f4-5.6 (gold).
There's a myriad of lenses to choose from; the one package i was looking at is thru Costco (red / L 24-105 and the 'same telefoto' w/ IS) along w/ a camera bag. The local big camera retailer here was matching it, but was offering the 'non IS' tele.. (surprise?)....
Never thought that a good size spend on cameras would be similar to buying a car!
