I am not familiar with your equipment, however, I would like to give you some advise. I have been shooting for over twenty years. I have used all formats from pinhole to 8x10 and have tried numerous film types and countless processes. Throughout all of this, I have learned one thing; better photograhy is in the eye and mind, not the equipment.(posted 9579 days ago)Looking quickly at what you currently have, I'm not sure what your goal is. You have lenses that cover 35mm to 300mm. Based on what you want to shoot, you should be in good shape. Now if you're not happy with the speed of the lens (F4.5) or the quality of the optics, that's another issue. I would suggest save your money and buy film.
Have a great trip!
