I'm going to buy a Canon D50, a rookie. Ask the master to teach you to match a lens.

First of all, correct the landlord's statement about the 50-day building. That's how I matched my contacts to 15-85. A novice cried her eyes out when she was matching a head upstairs. The fixed focus of 50 1.4 is not the header on the 50-day building, but a big aperture. Not worth it. To be cost-effective, 15-85 plus 70-200 is enough, which is more practical than what is said upstairs and saves more than 6 thousand yuan.
