Here is what I would go for if you want to cover the type of work you are doing
A-850
50mm macro for product as often feel 100mm might be a little too long sometimes. If the product shots doesn't need more than 1:5 ratio, even the 24-70 makes a good candidate.
Travel
Either 16-35 if you are into Scenery or 24-70 if you are more of street and stuff. remember there is always an option to stitch 2 images together using the 24mm end if you need wider view and best thing about this is the resolution is going to be more than just 1 single image. Cropping the 16-35 for longer view might sacrifice the image quality.
Portrait
24-70 makes a good portrait lens if you use 50mm - 70mm end. I use this lens a lot around 35mm-70mm for portrait work.
Here is another option...
A-850 + 24-70 f2.8 + extension tube so it gives you macro capability without much weight. But still give you much of the "range".
All the best.
