Hi,
Warranty is for 100 000 actuations. Replacing the shutter in the lens will cost about 500Euro.
I advise against buying second-hand body H1 and H2. In most cases, they can not be serviced.
If you buy a new body and you will be properly cared for the service (if you work a lot, I mean every day, there will be an expense of about 1200 Euros per year) I'll have the equipment in excellent condition.Even after 5 years. It is worth to send equipment to the site once every 6 months, unfortunately, in most cases, customers forget about it. This action is delayed as the equipment has already refused to obey, then generally it will be much more expensive. When buying new equipment you should purchase the "camera care plan" a very low cost and improving the user's peace of mind solution. Of course if you are professional photographer.
Best regards,
