How much does Canon 24-70 cost now? I also want to buy a 5D2 or 5D2 one, which is better, mainly for taking portraits!

60D or 7D plus the two heads you mentioned can open a photo studio, and the pixels of 1800w are still ok. 5D2 will be better, because the pixels are high and Quan Huafu. If you use a lens, you need to change from these two to 70-200. Because it is for the photo studio, you use more shelves, so you don't need to consider too many anti-shake problems. You can buy a second-hand little white generation, and the new one is only 8000, 24-.

In addition, pay attention to your studio, because if your studio is not big enough, whether it's an APS frame with a 50mm head or a Quan Huafu with a focal length of 70-200 mm or 70 mm, indoor shooting will not work.

There is actually a more cost-effective solution. Consider Sony's α 65,2400 W pixels. Although the high sense is average, compared with you, you won't lose to the high sense image quality. The price of the new machine is also cheaper than these two schemes. Photo studios pay more attention to pixels, you know, but Sony lenses are more expensive. You can find the best solution for you again.
