Yes—this is mainly an economic decision. The usual approach is to get a no-obligation repair estimate, then compare that cost with the current used value of each item and the cost of a replacement equivalent.

For the lenses, this comparison is fairly straightforward: if the optics and barrel are otherwise in good shape, a repair may make sense; if repair approaches the value of a good used replacement, replacement is usually the better choice.

For the camera body, be a bit more cautious. On an older body, repairing one fault can still leave other age-related parts likely to fail later, so repair can be less attractive unless the quote is low.

Photo count alone does not prove these items were only built for a limited number of shots, and lens longevity can vary a lot from one sample to another. Harsh temperatures and outdoor use may contribute to wear, but the practical decision is still repair cost versus replacement value.

In short: get quotes first, then compare against used-market value, with a slight bias toward repair only if you trust the shop and want to avoid the uncertainty of buying used.
