Binary Yes/No probably does not apply here. I can afford this level of sharpness, and not wish I had gone Full Frame.
An f-1.8 aperature, in a zoom is either insane, or a sign of things to come....
I mated this with my Canon 70D, and I am realizing a great pairing here.
Heavy, yes, but zooms by nature have more glass.
You can go cheaper, but have no doubt this is money well spent and your results need very little skill to show it. And, this is helping me take more and better photos, so my skills are improving even faster with this in my goody bag.
NO kit lens can compare. The ample 72mm front element adds weight and filter costs, while many Kit & Pancake Primes can share one set of 52mm add-ons. Smaller cheap glass will never outperform a quality larger lens (IMO).
A crop sensor lens, basically a limited & dedicated device to crop sensor bodies. I do not see this niche of the Camera Body market going away in the years I plan on still using this format, and this lens.
All this being said, I consider this money VERY well spent. On social media, I can fake telephoto by cropping a large RAW file (~20MB) to fill a 2,000p frame with more sharpness that F'book can handle w/o compressing out detail.
This Zoom will give me broad landscapes, night city scapes AND stars as well as provide all the Portraiture bokeh I could ever want. It works on several levels, and fits my desires more than adequately.
Best of luck, whichever direction your desires take you in your hobby.
