Upgrading lenses on a D90 to EF level

[peteck18]

Hi all,

I shoot with a d90.  I upgraded from a rebel, so most fo my lenses are EF-S.  I want to get better glass and am a little confused about the issue of using an EF lens on my camera.  I understand that there is a 1.6x crop factor, so a 50mm would really be closer to an 80mm on my camera (right?).  So here's my question.  Eventually I'll want to upgrade to a full frame, so I figure I should start upgrading my lenses to EF level so that when I buy the next camera, I'll have the lenses, spreading out the financial pain, as it were.  Does this make sense? On the other hand, I've read that using EF lenses on an APS-C is less than ideal.  What do you all think?

Thanks!

I don't know that this is a good plan.  How long in the future do you expect it will be until the FF upgrade comes?  Also, will the FF upgrade be a new or used camera?

Another point because it seems you like almost everyone is stumbling over the ridiculous "crop factor".  Did you get the ef-s 18-55mm kit lens zoom with your 90D? If you set it to 50mm and look through the viewfinder you will see exactly the same thing as the ef 50mm f1.8 lens will get. EF or EF-S makes no difference.

But let's rethink the upgrade goal. A far better way to go is mirrorless and that means R series lenses.  They will not work on your 90D but that is the future, not EF. If on the other hand, upgrade is near or you are buying used I suppose EF will last you quit a long time. Unfortunately we are in that twilight zone between a new format and the old.

IMHO, if I had a 90D, I would never buy EF-S lenses at all.  What do you think a FF camera will give you that your 90D doesn't?  The 90D is a very capable camera. It is one of the best cameras ever made. It is going to be difficult to buy better particularly if you pare it with top of the line "L" lenses.
