I’m delighted with my new D500 but, unlike my old D300s, it doesn’t have a pop-up flash. What compact flashgun would you recommend that’s smaller than my SB-900? Conrad Dobson, via email

Jason says... The lack of a pop-up flash on the D500 is a shame, as it would have been useful not only for adding a bit of fill-in lighting, but also for wirelessly triggering off-camera flashguns. (In most current Nikons, this is easily done by setting the pop-up flash to Commander mode.)

Nikon’s smallest and cheapest flashgun is the SB-300 (£120/$150) but the SB-500 is a better buy, at £195/$250. It’s still fairly compact, but more versatile. It features wireless Commander and Slave modes, making it more useful for creative lighting techniques based on multiple flashes (including your SB-900). It even includes a secondary constant LED light, which is handy for close-ups and shooting video.
