I've just bough this week that lens and I've been testing it for a couple of days. I was hesiting to buy it for weeks, I mean +/- 250$? Why those Canon Lens arr waayyy much expensive then?
Well you got no auto feature, so you have to well understand basic of photography ( iso, f/ shutter speed ) and everything will go alright. It's good if you just started and want to sharpen your skill. If you like a minimum of the challenge that bring manuel mode, then you will love it. Take great photos, all aluminium alloy housing, good looking.
I took picture of jupiter yesterday and i was able to make it appear with the real color on the picture, grey in the center with the 2 orange stripe on each pole, and a picture of the moon who take 80% of the size of the picture.
If you hesitate and wonder: "should i get it or not."
You should, I was worrying too but it really worth it :)
Dont forget to get yourself your T-Mount adaptor ;)
