Venus is very difficult, as it's thick atmosphere is

a) extremely dense, crushing stuff under it's pressure (it has a pressure of 93 bar, so about what we have here at over 900 meter/1000 yards underwater (which is too deep and too much pressure for most submarines btw!),

b) toxic and corrosive, so probes tend to get destroyed before they even touch the ground even if they could withstand the pressure, and

c) absorbs and reflects radio waves, so even if the probe survives, if the signal emitter ain't strong enough, you'll never know.

Also, considering the thickness and composition of Venus's atmosphere, even if all those problems would be solved, I'm pretty sure you wouldn't see anything in that thick, dense fog...

Probes have already managed to survive on the surface for a short time; (Venera 13 lasted 127 minutes after touchdown) we could work from there on producing something more durable.

Venera-D is currently proposed to put a probe on the surface designed to be able to survive for 90 days, with a proposed mission date of 2026:
