My understanding is the LW tended to favor single engined recon a/c over the UK like the Bf109G-2/U2 and Bf 109G-8 for high alt recon missions, rather than the slower twin engined a/c. There was a Fw190A-5/U4 recon a/c, although I have no info on Western Front deployment, it would have been used as a low level maching im sure.
The Fw189 was a tactical recon machine, unsuited to missions over the UK, and the Ju-86p was too vulnerable by 1943. Night time? well, sure, but you dont get much info, so you needed a recon fighter that could fly high, and fast, and get out of there in a hurry. The Arado 234 and Me262 (none were ever flown as recon birds past prototypes) were not available untill after Normandy.
This did limit their efforts, but the biggest problem was not that they did not know about the Allied buildup, they did, it was WHERE and WHEN the invasion was going to land, that was the question they failed to adequately answer in a timely fashion. It is remarkable that even after the Airborne Landings and the Seaborne invasion force was at sea for many hours, that the fact the Allies had landed in Normandy *as the main invasion effort* ,was still not fully understood by the German High Command untill well after the fact, despite being braced for that very eventuality.
I would say the failure was more on the intelligence side, rather than the recon side, although they are linked, as intel gets its info (at least some) from recon sources.
