I am not exactly new to photography as I have enjoyed using a camera for many years but have never really looked into the technical aspects. Recently I inherited my Father's camera equipment and now I want to know how to really use all of the pieces.

The camera (film) is an OM-1 F1-8 purchased in 1974, along with the camera there are the following
the original Olympus lens 50mm
Olympus 75-150mm lens
Olympus teleconverter 2X-A 100mm F2.8, 135mmF2.8, 135mm F3.5 200mm F4, 200mm F5
Panagor auto macro converter 1/50mm
Soligor lens 1.8 30 mtre
Sigma zoom master 70mm

I hope the above descriptions make sense.

Apart from the original lens
does it make sense to have all the others
how do they work in conjunction with each other i.e. what sort of combinations can you use
in what situations do you use the various pieces

I also use an Olympus digital SP-56ouz and it has been interesting taking the same subject with both of the cameras

I look forward to any and all advice
Thank you
