Hi, I am a complete novice when it comes to photography but would like to be able to take good close up shots of my watch collection. A friend of mine has given me his Nikon D3300 to play around with. It comes with an 18-105mm lens but no macro. I'm not sure whether to buy this combo from him and in addition purchase a macro lens and tripod, or buy one of the macro lens attachments you can attach to an iPhone. I'd only really use the camera for watch shots and cannot imagine getting seriously into photography. Can anyone please recommend a macro lens to go with the above camera within say £100 (is that even possible?!) If I go for a phone lens, can they still be used if my phone is upgraded or will I have to buy a new one each time I upgrade. I believe I could buy something decent for less than £100. I have been reading various posts on this forum and that has been very helpful but would be very grateful for any advice from the knowledgeable OF members. Thanks!
