I’ve purchased from HK in the past also and even after paying duties it still worked out cheaper than the high street here. If you do buy from B&H you will most likely pay more duty than HK so bear that in mind.
I bought from HK a couple of times… had to pay taxes etc but it still worked out cheaper than here… I too have the 35 f1.4…. brilliant lens the only downside of which is that you’ll want the 85 f1.2 next…! Watch this space…! Its getting closer…………………
