1) Numbers
There is no doubt the size of Ottoman armies were sistematically exaggerated by their foes, as usual, but as we don´t have the detailed musters and payment documents (at least available to western scholars)that we have for western armie from the second half of XVI century we can´t exactly tell what the real figures were.
2) weaknesses of Ottoman armies
They are comparative to western armies, they were not really evident until late in the XVI century and they were not evident at all against non European foes.
a) Outdated siege techniques againnst the trace italianne, so that Ottoman sieging forces had to rely mainly on mining.
b) Ottoman armies never adopted the pike, so that infantry remained very vulnerable to enemy cavalry, and exception for the janissaries before the end of XVI century, Ottoman infantry lacked discipline
c) Ottoman timariot cavalry was also indisciplined and was unavailable for winter campaigning
d) Fire weapons were slow to replace bow, still the basic weapon at the end of the XVI century.
In general all those weaknesses revealed as Western armies become better disciplined and organized, but in the XV century Ottoman armies were on a pair with the best of Western armies, they just didn´t keep the pace of change, and here culture could be probably the main reason
