Recommended Nahlinsenset

I ordered the Nahlinsenset for my Canon 55-250 STM. I was about to buy a macro lens, but then have first resorted to the close-up lenses by Polaroid to see if the macro range is at all interesting to me.
The set comes in a nice bag with small mesh pockets in the inner part of the four lenses. The threads engage very clean and the lenses make ever a high-quality impression.

First I put my camera on a tripod and screwed + 2 lens. This makes for a telephoto zoom lens with 250mm focal length actually the most sense to that later. I have a black printed side taken as a goal because you can see there well fringing or diffraction blur.

The magnification in this case is 1: 2. Although the autofocus works, but you should already manually focus to get good results. We can already see strong fringing in black lettering. Fade help here and from screen 13 I was able to achieve very good results.
The +4 and +10 lens I screwed only to test to see what happens so. It was natural to expect that the fringing were violent and the focus range is extremly low. The +4 would still, but you have to stop down so much that it takes a lot of extremely light and even then one has strong diffraction blur.

The lenses for this price of course not achromatic and so you have to live with the chromatic aberrations, and I have not expected anything else. What you need from the set?

+1 Hardly makes a difference
+2 Super for long focal lengths of 150mm
+4 Great for shorter focal lengths as a 50mm or 85mm fixed focal length
+10 To experiment

I think the best results with close-up lenses will be achieved with a long focal length as 250mm and the +2 close-up lens. This is really neat. For +4 at long focal length you have to stop down too much. Who wants to really good quality should pick up the achromatic or macro. To test and still sizable pictures of this set is great. But as I said it's the combination of focal length and diopters. As I review the product and not the price, there are 4 stars.
