If he’s into street photography then a small camera with a prime lens would be ideal. Anything else will become a chore and you end up just not taking the picture. I had an EOS1 mk3, 24-70Land 70-200L both F4 and 50mm F1.4. Sold all and got a rangefinder Fujifilm xpro2 graphite edition(relates to finish of the product)with a 23mm f2.0 lens. Got the grip and a thumb rest as an accessory. Absolutely love it, intuitive versatile always on hand to take a photo. Speaking of photos, fantastic to say the least. Real, 3D, gorgeous color and plenty of advanced options.
