想听听大家对全幅相机的看法，正在考虑是否进全幅相机

考虑进一台全幅相机，如果有了全幅相机是否有必要保留现有的APS-C相机？由于APS-C相机的 1.6倍的放大效果，打鸟是否用APS-C相机比较好？下面是我在网上看到的一段对全幅相机的评论，想听听大家的看法。谢谢！

“Now, 95% of the people seem to believe that full frame causes much better image quality, but is this really so?

This is the information I gathered, but I would like to hear more from more experienced people. This because I'm comparing 7D and 5D

If you look at high quality lenses they work nearly flawless in APS-C, but have great problems in full frame. The problems we are seeing in full frame are:

• blurriness at the edges

• vingetting so the edges are much darker

• way more chromatic abberation.

Other full frame problems are:

• lenses will be far more expensive to counter above.

• heavier lenses.

• 1/1.6 less zoom. ”
