So this is what I already did. But the only difference is that it's 'hidden'. Which of course I don't want. I want people to be able to find the Camera + Lens when they search for it. Because it a way bigger adjustment than just changing the color of a sweater for example. 

I asked if its possible to merge all those products to one page so google wont see them as duplicate. But I guess it is not.

I think I should use caconical urls or put the pages on no-index.

Hi, 

So Google doesn't like it when you have duplicate pages, but when I have a camera (lets say Canon 250D), is have a description and price comparison.

But the Canon 250D also has combinations (Canon 250 + 18-55mm) with a lens. So I duplicate the page, same text (sometimes adding info about the lens), add new meta title and descripton. It will have a different URL. 

Google will still see that as duplicate content. Now I know I  could use Cocanical URL's, but my question to you is:
I know it possible to make product variations. But is it also possible to have 1 page and 1 urls and variation whith different price comparisons? 
So when I enter the page on Canon 250D, I could click on 250D + 18-55mm lens and withing that same page a new price comparison loads. (without have to change the page)

I added the url to the product. Below the prices you can see the variations of the camera, which now links to a new page so it can show the price comparison. 

I hope my question is easy to understand. Thank you very much.
