However, they work very well. I haven't experimented fully with them yet, but I did just spend about an hour taking photos with the +10 and +4 stacked together. Tomorrow I intend to try out every combination I can. Yes, they do have a very shallow DOF, but for the sort of macro photography I like, that's not only not a problem but ideal.
This is definitely a product I would recommend for someone who wants to give macro photography a try but is hesitant to spend the money an actual macro lens costs.
I was thinking of just going out and buying a ~300$ dedicated macro lens at first ... but then I quickly changed my mind when I discovered these.
I, like many other photographers out there, am new to the DSLR thing. I recently bought a Canon Rebel XS (1000D) to really get into photography.
Macro photography just so happens to be one of my favorite styles. But, I'm not made of money. So these were a perfect buy for someone who is just starting to get a hold of different styles of shooting. (Macro, ... etc)
The build quality is very good for the filters themselves. The metal rimmed glass feels secure and safe at the top of my 18-55mm kit lens. The filters simply screw on to the front of my lens and are easily stackable.
The build quality for the pouch on the other hand, is just some sort of synthetic thread. I just got these filters in the mail today and the pouch is already starting to tear at it's seams.
This really doesn't matter to me. I just care about the filters lol. And for the price, about 11$ for me here in the US, how could I go wrong?
The filters came relatively fast with the free shipping. They were in a small cardboard box and were heavier than expected.
No ACTUAL instructions were included with the filters, but there are some guiding sentences on the box they came in.
The bottom line is that if you are new to photography and like shooting macro or close-up ... BUT don't have the large budget for investing in a dedicated macro, these diopters are perfect for you. If used correctly, you can achieve a very impressive picture quality.
I wasn't disappointed when I bought these. I sure that you won't be either. :D
