    These look interesting. The kit comes with stick on lenses that magnify to up to microscopic scale. They stick on with tape and unlikely to have a working life as long as the bigger, metal bodied, clip on type we might be familiar with.
    I've just had a quick go at a convention and might invest in a set.
    Anyone have experience with these or competing lenses?

    Not an interesting pic but better magnification than im used to. 20180306_122243.jpg

    Any time I see the words "stick on" I'm leery of using them on my *precious*. :eek:

    Stick-on doesn’t stick to my gloss black 7+. I’ve tried all sorts of things. Gorilla tape falls off after a short time.

    I’m very happy with the quality of the Moment Macro but they only attach with a case. They abandoned the stick-on adapter plate. People don’t get them properly centred.
    The downside to the Macro is that it is just one magnification and just one focus distance - fairly limited. I find I get much greater use from less powerful close-up lenses.
    I haven’t had the chance to try much higher magnification than the Moment Macro. Might be fun. But I would have to remove my case first and after use remove the stick on thing so I could put my case back on.
    A problem with the new phones is the camera lens sticks out from the phone quite far. You wouldn’t want the add-on lens to touch the phone lens.

    A major issue with phone Macro is they are all wide angle close up. The phone is so close to the subject it blocks the light. I want telephoto close-up. DSLRs commonly have 200mm macro lenses for this exact problem. Much nicer subject/background isolation. Better working distance. It’s pretty hard to sneak up on a butterfly at the best of times but 4cm away is impossible. Unless the butterfly is dead.

    Edit: the Moment Macro is a true flat field lens, without distortion. Lines stay straight and in focus right into the corners.

    Since I’ve seen you posting very close-up photos I presume you have found some sort of close-up or macro lens. What did you find? Are you happy with it?

    I haven't. I do have a couple of low end macros I've had for years but the gain in magnification is offset by a drop in quality so I rarely bother with them these days. I just use the phone for close shots. As long as I don't use too much zoom it does quite nicely. I don't get the magnification I want but I prefer the quality.

    Here's a couple with no extra lenses.
    The quality on this first is too low for production pics imo. Too much zoom.

    But that's quite nice.

    Could be the Gorilla Tape/Gorilla Glass transmogrification whereby one uses so many strips, to hold on previous strips, that the underlying structure resembles something out of a John Carpenter movie with one eye. Or something like that ;)

    You've made me rethink my macro options and I've been re-testing my assumptions. Although my native lens gives me zoom and quality I'm happy with, it's not as good as even my cheap macro in terms of magnification.
    Here's the same spider with and without a macro.

    They look good on my iPhone so I had to switch to my iPad to see the quality issues you mentioned. The Moment Macro is 10X which doesn’t give me enough for tiny subjects. The problem is that it’s a wide angle macro so you end up about 2 cm from the front lens element. Not to mention that you end up blocking the light because you’re so close. Too close for many subjects. I’ve been trying to use the 2x tele lens on the iPhone for close ups since it gives more reach and has a narrower angle of view, which is good to narrow the area taken in in the background, especially useful when the background is untidy. When you zoom in with your standard lens you are on the same path. The tele lens is f2.8 instead of f1.8 for the wide angle so there’s a little more depth of field, but never enough. There’s always a problem with anything. The tele doesn’t focus nearly as close as the wide angle so I’ve been using close-up lenses to allow closer focusing. What I really want is a telephoto macro. I sure wish there was a universal lens mount for add-on lenses so I could get lenses from different manufacturers and they would all fit one mount. The worst set-up is the clip-on type. Alignment is always a problem.

    Well, I suppose that’s why I bought the Beastgrip Pro because of the 37mm thread but it does rather feel like cracking a nut with a sledgehammer. I tried the wide angle lens that came with it in Namibia and was very disappointed with it although I have now read that you need a slight zoom to get rid of the vignetting which I didn’t know at the time. The macro lens seems more promising although it still doesn’t feel as sharp as some of the macro shots I managed to get with the single lens on the iPhone 6 with the olloclip which I absolutely loved and this was even without a tripod. I need to experiment more with it because I don’t know whether I have the correct placement of the lens. It does work with the zoom too. Also, I would try it with a tripod as well.

    Here’s a typical shot without a tripod but I don’t think I quite had it right. I feel I could do a lot better but I would love to compare it with the iPhone 6 and olloclip.

    It’s a great image without a tripod, but it’s just that tiny bit out of focus. It’s only a tiny bit, but it makes all the difference with these close shots. The tripod would probably have made the difference, but who has a tripod set up on a flower just ready for something to land on it? Chances are the insect would land on the flower next door. :lol: I’m hoping that you all keep experimenting and find THE lens that does the job.:D

    I just can’t get the focus much better and if I compare it with an image taken with a x2 zoom without a lens and cropped, the cropped version is still sharper. I have come to the conclusion that the single lens on the iPhone 6 with x15 macro lens works the best for really closeup. I took these images below with this configuration and I have never been able to get a better image on my iphone 7+.

    These are wonderful aren’t they. I struggle with the 8+ and the Olloclip.

    I agree with rizole sometimes you can get good results with a steady hand and the right light. Remember my fly? Just the phone camera no add-ons here.

    It’s my impression that most of my focus problems are the result of getting closer than the closest possible focus of the lens or lens combination in use. This results in the main surface of the subject being slightly out of focus while something slightly farther back is in sharp focus. Your fly photo here is a perfect example.
    The close focus limit is especially a problem with the 2x lens.
    Even with macro or close-up lenses I think we tend to overestimate the closest focus range of the lens and this is one place where pushing the envelope just doesn’t work.

    Fantastic sharpness on this.

    Yes, I have definitely decided that I will not bother with a macro lens on my 7+ but may well borrow my husband's 6 and have some more goes with that. Mostly the serious magnification is unnecessary and anyway if you grab your phone and fumble around trying to put on a lens the moment is often gone.

    I spend a lot of time readjusting the distance and often snap images continuously to make sure that I have at least one image that has the correct focus.

    You might want to try the CameraPixels app. It has some features that are a bit hard to find. Among the bracketing options there is focus bracketing. 10, 20 or 30 steps. Also available with RAW files. You don’t have options to set the near and far limits of the focusing, as you would in a typical focus stacking app, it just shoots the entire focus range. But if you have enough focus steps the extra focus steps can be ignored. And.... if you make your focus brackets with a tripod... you have a good focus stacking set. So far, Affinity Photo is the only app capable of focus stacking, even with DNG files.

    CameraPixels does offer the option to set the focus range for me (iOS 11.3.1, iPhone 7). Maybe that's an iOS version/phone dependent feature?
