Do you think that the heavy price tag on this lens makes it worthy?
The price tag as originally advertised was steep. But I managed to get it for 788AUD (793USD, 637EUR, 510GBP, 6150HKD at today's exchange rate) delivered, which after claiming the tax back (as I am heading overseas) will only cost 716AUD (or 720USD, 579EUR, 463GBP, 5595HKD).
On a crop body it would make an excellent walk around lens. Almost like some mirrorless cameras out there.
Though heavier than the 40mm pancake and the 28mm f2.8 lenses, on the 5DII it feels extremely well balanced. Its focus is fast and silent, just like any other USM lens. I haven't tested (nor will I have the time to) its image stabilization.
On the 550D, it becomes front heavy. But makes a compact kit almost like the cheapo 18-55mm kit lens. Attached is another photo taken with the 550D for the same scene in the previous image (as well as a photo of how the lens looks like on the 550D).
I am going overseas and will be leaving behind the bulky 24-105mm behind. Only taking this 24mm and the pancake with the 550D. Let's see how they'll fare.
