Once again I return to testing a Wide Angle Add-on but this time it is actually a Wide Angle and Fish Eye Clip-on and it is for a mobile (cell) phone camera. Again it was very cheap! Ebay £1.20/$1.80 – so I was not expecting much! The question is naturally if you are entitled to expect a lot? For that low price! Well that is an open discussion without much of chance of a single correct answer! So … I will mostly be checking out if the kit is usable at all and show you a few sample pictures so you can see yourself what to expect!
I have used my iPhone 6 for all the sample pictures! But you should get the same results with any decent camera. It will fit any mobile (cell) phone camera as long as the camera is surrounded by a, mostly, flat area. You might have to slant the clip-on to one side so that you will have something for the clip-on to clip on! See the picture above or on the side – in which you can see that the bottom part of the clip-on is actually shorter than the top part!
Be sure to check out my review of a 0.45x Wide Angle Add-On for ordinary cameras!
What I got was 7 parts; clip-on holder, 0.67x wide angle + macro combo, 180° fish eye, two plastic lens covers and a small pouch to keep it all in. That is if you do not count the two small plastic bags that contained the lenses. You could get it in several different colours – I got a rather nice shade of blue!
Looking at the lenses mechanically they are very well built! Made from anodized aluminium and have threads that work very well. Here you can see the two-part wide angle clip-on as separate pieces. This is not a very advanced optical construction – just two lenses. But they are at least made of glass! As far as I can see there is no anti reflex coating on the lenses. You screw them together to use the 0.67x wide (as you can see on the first picture, above) and unscrew the “front lens” and use only the part marked “MACRO” when you want to take macro pictures. 😉 You only get two lens covers – for the front of the lenses but no back covers! So the plastic bags are kind of necessary to keep the rear lens elements clean! The clip-on is (naturally) made from plastic and is spring loaded and also padded to keep it attached to the phone without leaving any marks! It will fit on almost any mobile phone camera – as long as there is at least some flat area around the lens! It does not matter if the lens protrudes a bit as long as it is less than 3 millimetres – just over 1/10th of an inch and the diameter of the protrusion is less than 9 mm! It is OK attached tho the phone but it will fall off if you are a rubbing it a little bit too much and too hard against other items.
Looking at the lenses optically the story is a bit more varied! Starting with just the macro lens. First of all – it gets you very close to your subject! Its depth of field is very narrow – just a few millimetres or 1/10 th of an inch! It does give reasonable sharpness in the centre of the picture so pictures like the sample picture on the side works surprisingly well! But note that this type of motif is ideal for this lens as that there is nothing along the edges of the picture so except for the middle of the picture everything else is in a … rather nice soft blur! You can also see the difference in close up limit without the macro lens. The two first sample pictures illustrate how close as you can get with and without the macro lens. By taking into account the shallow depth of field and moving the camera you can get more of the flower in focus as the third picture (of another flower!) illustrates. Just click on the pictures to see them full size!
I have added two more sample pictures that I think shows very well the sharpness that is obtainable with the macro lens. Skittles – I love ’em! 🙂 Note also the difference in the depth of field between the both photos! The second one – without macro lens – is practically sharp all over the (too) small bag of Skittles! Check out the full size macro picture and see how sharp the printed dots are! I also think that the colours comes out as they should – with no changes at all! The iPhone was set for fully automatic and I used the standard Apple camera app! That software can naturally have compensated for any change in colour temperature – but I do not know if it has! These are the results you will get also!
Using the macro lens with a flat motif, the shortcomings of this lens is very obvious! It will not give a sharp picture over the whole area! Feels a little like you have twisted the zoom during exposure! Is this really useful? As always it depends on what you want to use the pictures for! It is rather cool to be able to get as close as this and the pictures do have a sort of novelty feel for macro pictures with a mobile camera – at least for the flower pictures above! The two pictures to the left also illustrate how close as you can get with and without the macro lens. The macro picture is taken at the very centre of the other picture.
Conclusion is that this macro lens is OK for “natural” non-flat motifs but is not very suitable if you want to document your stamp collection!
The other two lenses
First of all I have to really stress that these clip-ons does NOT give sharp pictures!
But as always there are different levels to sharpness – and also the position of sharpness! Another important factor to get maximum sharpness with this clip-on is how well centred it is over the camera lens!
There are two clip-on lenses to compare; a 0.67x wide angle and a fish-eye.
All lenses can be attached to both the ordinary front facing camera and to the “selfie” camera. It is actually a little easier to attach the lens to the side where the “selfie” camera is, because it is located further from the edges of the phone. I expect that the close-up lens will not be of any real use for the “selfie” camera! There is soft plastic area on both clamps of the clip-on that press against the phone so as to not scratch it.
You need to be very careful about centring the clip-on exactly in the middle over the camera lens! Look through the clip-on lens when you do this – you will then see the camera lens very clearly! Make sure you get the camera lens exactly in the middle. Also, when you switch on the camera you will see the dark vignetting in the outer edges/corners. If it looks as if the picture not is centred then move the lens a bitt to get it centred! Be careful once you have it in position as the whole clip-on – lens combo is quite easy to knock off the camera or move it away from the centre position.
Wide Angle Lens 0.67x
I will start with the wide angle clip-on. First picture is original iPhone lens with no clip-on. Second picture is with wide-angle clip-on. Click on pictures to see full size pictures! The wide angle does give very powerful vingetting, that is: dark corners! It also gives a big drop in sharpness, especially along the edges and the corners. Or I should maybe rephrase that and say that it is only reasonably sharp in the centre of the picture – sharpness drops significantly as you move away from the centre part! But even in the centre there is not as good sharpness as without the clip-on! The picture also has most other forms of distortion!
The difference to the original camera lens is striking! So picture quality in just one word: BAD!
As above the first picture is the original iPhone6 picture and the second picture is with the clip-on. The fish-eye clip-on gives almost a circular picture with black sides and corners! Notice the very unsharp branches on the left! Not much good to say about the picture quality at all!
As for the wide angle clip-on: the quality in just one word: BAD!
Well, this is very cheap product and the wide angle and fish eye lenses are almost useless due to their low picture quality! Still, the close-up lens is quite fun – but only when you have the motifs just in the centre! The clip-on is also quite large and is easy to knock off.
As the close-up lens does give ok sharpness (at least in the middle of the picture) I still think it is a fun thing to have for less than $2! But you might as well loose the other two lenses!
You can buy the same lenses – for a few dollars more – with magnetic attachment instead of clip-on. Probably even easier to knock off – but if you are just using the slim close-up lens it might be a more handy and compact solution!
