Thanks for your reply! That combo would kill my budget, right? I was hoping to keep it under 1500eur. I've seen people using the ronin-m with the Ursa mini. Of course they take out the batts, side handle and use very light lenses, but even if i use the sigma 18-35mm, the weigth is still under the ronin-m limits. Do you think it would not be able to balance?
