Hello again,
First of all I would like to thank you all for your responses. I will certainly give all their due
consideration in helping me make purchases.
May main concern was trying to utilize what I had as much as possible. From all the reading I have done, manual mode was going to be my only option no matter what new camera I purchased, with these lenses. I have looked and narrowed my choices down to either Sigma or Sony. The reviews and comparisons tell me that the Sony a6300 is the most bang for my buck right now. I do like the Sigma Merill SD1, however I don't believe my lenses would have full function anyway. So, when looking at cost, for right now, the Sony a6300 seems the best choice at 3.5x less the cost. I just have to buy an adapter. As time goes on, I would purchase E mount lenses for the Sony for full function and capability.
Thanks again,
R.T.G.
