Here’s my rewrite of the grammar problem mentioned in my previous post.

First, the original:

These pioneering innovative cameras each have a novel feature which sets them apart from the pack

Yuck, that’s just terribly sloppy, even though it sounds okay at first. Now, the rewrite that only solves grammar problems:

Each of these pioneering cameras has a novel feature that sets it apart from the pack

“Each” is the subject (singular)

Therefore, “has” is the correct verb to use

It’s the feature that sets camera apart, not the camera, so it should be “that”, rather than “which”.

Also, if “which” were going to be used, it would need a comma before it to indicate that it’s an independent clause. That vs. which is tricky.

Even better would be to use a consistent metaphor.

These cameras contain pioneering features that allow you to explore new photographic terrain

That’s a little better, though I’m not happy with “pioneering features,” since features can’t pioneer anything. The features are actually the result of pioneers in the field.

Each of these cameras has a novel feature that’s more than a gimmick

That’s more the direction I’d go. Consistent, short, but interesting language. It also invites the reader into a debate. “Oh yeah, well maybe I’ll think it’s a gimmick!”
