Panasonic Lumix S 70-300 mm f/4.5-5.6 Macro O.I.S.

I've been a Panasonic/Lumix user since 2012. Their cameras are amazing but their lenses are just good enough, in general. This one is not inexpensive, so it's just good enough for the price. It's not too heavy for 135 Format. Since they didn't mention freeze resistance, I will assume that the weather-sealing is adequate for light weather. I have been able to photograph stars at the wide end, but for some reason, the S5 Mk II refused to get any photos at the long end in the dark. That was the main reason I bought the lens. It's not that an aperture of f/5.6 is so bad. Certainly when you're photographing from a distance you can use a deeper Depth of Field with a larger sensor. Dual I.S. seemed to perform well. During daylight, it focused accurately, though focus was a bit slow. Hopefully, a firmware update would help it.

Excellent lense, very good build quality and sharp pictures. Great lense for any collection

Had this a couple of months now, everything as expected from panasonic. 5 stars

Such a great telephoto lens. Light weight and portable. Can walk around with this lens on my camera all day without it feeling tiresome. Great range and macro function. Images are super sharp. Have not detected any softness in images taken with this lens. The OIS works great and helps in low light situations. This has become my favourite telephoto setup now.

I thought this lens after trialling it previously. It’s light, very fast to focus and incredibly sharp all through the focal range. With the high ISO performance of the Panasonic bodies it becomes a great lens for capturing moments at sport. The close up abilities are good enough to capture individual flies too. Although it’s missing the wide apertures of more expensive lenses and the full reach of some other brand lenses I think that lens is an almost perfect compromise for me. I will get a 70-200 f2.8 at some point but this will still get a lot more use.
