I usually talk about how to save money however we all have our hobbies. I did buy this second hand and saved at least $300, so perhaps the money saving tip for the day would be to look on kijiji or craigslist or any second hand classified of your choice before heading to the store for your money burning exercises!
I have a 35mm which sometimes I feel is too close, something wider would be very nice to have so I picked up an 18mm, and I went shooting.
I enjoy this lens quite a bit, some have mentioned the sluggish autofocus due to being an older lens but I had great experience with the autofocus, it hunts a bit during close focus situations.
