Landscape shots can be taken using pretty much any lens. Astro shots would generally require wide-ish angle lenses (28mm, 24mm, 20mm etc). The Panasonic is a crop sensor camera, so the focal length you see advertised for the lens would be doubled to give the equivalent field of view for a 35mm (full frame) camera.
So, if you want a 24mm wide angle view for the Panasonic, you need to buy a 12mm lens.
For astro work, you generally want a reasonably "fast" (larger aperture) lens (f2.8 or faster) to minimise the use of slower shutter speeds. These type of lenses tend to be heavier and more expensive. A fast lens is not a prerequisite for landscape shots as the lens is normally stopped down (set to a smaller aperture F8.0-F16.0) to get greater depth of field.
Looking at your budget, I cannot see many wide angle lenses with a reasonably fast aperture, especially if buying in the UK!
If your nephew is OK with manual focus, Samyang sell a 12mm F2.0 lens but it does not have autofocus. This can be had for around £260.00 in UK. It gets pretty good reviews.

There is also a Sigma 16mm F1.4 lens that does have autofocus and can be bought for around your budget. This is a very fast lens, good for low light with an equivalent view of 32mm, so it may be OK for astro. It also gets very good reviews

I'm not familiar with the M43 scene but hopefully others will come along soon and give you some better alternatives within your budget. |
