Hello

I've been using my k5 for almost 4 years now but it is only now that I discovered that the option for 2nd curtain flash sync is disabled if non A lens is attached to the body. I do have one AF lens and a few manual A lenses and a non pentax external flash but I often times want to use 2nd curtain sync on my non A lenses
My question is Is there a work around on this? Also I am contemplating on buying another apsc pentax body.
My considerations are efficient focus peaking with tilting lcd and manual flash control for manual lenses addressing my flash issues on k5 and of coarse no known mechanical or hardware issues.
