You can be certain of one thing: Google does all they can to give people the info they are looking for. Tools on how to tell genuine search querry info have changed over time - and will change. But the goal remains the same.
That's why I'm certain that duplicating content for no reason but trying to "outsmart Google" is not going to end well. At least not in the long run.
You can pull tricks, play cat and mouse. Might work if you are selling something, need to be highly ranked and sell as many as you can as quickly as you can. Still, even for those purposes, I'd say it's also better in the long run to not try tricking either Google, or visitors.
The beauty of hyperlinks is what they do. Making an article on low light shooting, and linking it to each camera would make a lot more sense. It would also make sense to let the visitors know what you wrote here: it's practically the same for all these cameras (perhaps include links to each camera page as they are listed).
It is what I do and the results are just fine in terms of Google ranking. Also the website is easy to navigate and understand.
For topics that are similar, but with enough difference to call for (need) separate pages (with seaparate titles) in order to be properly explained, I make separate pages. Info does have many similar keywords, but it's not the same. Such articles are ranked in a way described in the previous answer here as "doorway pages" - one Google search querry returning 3 different pages from my website as the top 3 results. However, the topics are genuinely different and each page explains a different aspect, or even term, but with some similar keywords. Photo example I can think of would be separate articles for "camera lens", "camera li-io batteries", "camera case", all being listed when someone searches "camera equipment" (if all those terms are not considered equimpent and such word would not be used in the articles, then I've chosen a poor example, sorry).
