Sony has another round of big trade-in bonuses for the A7 II, A7R II and A7S II cameras through April 1, 2017. You can trade an old DSLR or lens in for credit toward a Sony camera or lens and get up to $480 in bonuses on top of the trade value.
B&H has a dedicated page set up so you can select the Sony camera and/or lens you want, then choose your gear to trade in and get your instant rebate and trade-in bonus all at once. For example, the A7R II retails for $3198 and has a $300 instant rebate and $480 trade-in bonus for a $2,418 price before counting the value of your trade-in equipment.
