I want to buy a lightweight SLR bag, but mine is Canon EOS REBEL T2i. What model is it? Is it the same as 550D? What kind of good to buy?

EOS REBEL T2i should be called foreign 550D model ~ that is, domestic 550D ~

It belongs to Canon's entry-level machine ~ not very big ~ ~

If the bag is generally better, buy it from Le Shebao. The quality is very good and the price is not very high ~ ~ ~

There is also the domestic Hemu ~ ~ which is a canvas series ~ with fashionable style, good workmanship and high cost performance ~ ~

Because I don't know your budget and what style you like, it's not good to recommend the model ~ ~

Check the relevant information on Taobao or Zhongguancun and Paopao websites, and evaluate the use ~
