Nikon 40mm f/2.8 Micro. Happy with mine; super sharp, no complaints for electronics.

Hey! For small electronics, consider a used Nikon 40mm f/2.8 Micro. Super sharp for the price! Check KEH; you might find one for around $200. Great value!

For electronics, macro's key. The Nikon 40mm f/2.8 Micro is sharp and around $280 new. Unfortunately, I had issues with chromatic aberration on cheaper lenses. Consider extension tubes with a 50mm f/1.8; not as good as a true macro, but budget-friendly and surprisingly decent. Worth considering for the long term, right?

Instead of Nikon, check out used Sigma Art lenses. They often outperform Nikon's primes optically for less. A used 50mm 1.4 Art can be found around $400. Factor in potential repair costs, though. Tamron's SP series is another decent option, but Sigma generally offers better bang for your buck in sharpness per dollar.

Be careful of reflections! Consider a used Nikon 40mm macro. Make sure to use proper lighting; avoid overheating electronics.

DIY'er? Nikon 40mm f/2.8 Micro. Sharp enough, about $300. Build a lightbox; save pro fees!

My Nikkor 40mm macro is sharp. Had it 10+ years; still happy. No complaints, works well.
