Letโs talk about macro photography.
Do we need a macro lens to explore the world of minute? You are fully aware of many original or third party standard prime/zoom lenses have their macro mechanism to magnify objects from their minimum focus distance (MFD), respectively. Alongside, there is a suggestion of using telephoto lenses due to their narrower angles that enable them to zoom for close-up shots though their MFD could be a few times longer than those standard prime/zoom lenses in general. Another method is mounting one or more extension tubes in between a lens and the camera body by distancing the lens elements and the camera sensor to produce magnification. Usually extension tubes are hollow but some premium grade ones may have electronic contact points to record EXIF or AF of each photo being shot.
Are standard prime/zoom lenses or telephoto lenses or mobile phone cameras substitutions of macro lens? Shall I rephrase the question to: How far is a mobile phone cameras being able to perform macro photography in the absence of a macro lens?
I have taken 4 shots on the same white Adenium or also known Desert Rose using a telephoto lens, 2 standard prime lens and a mobile phone camera. Before placing a shot, I mounted the camera and the mobile phone on a tripod to ensure stability. The tripod was placed as close to MFD so that Adenium would turn out to be as large as possible on the picture. I took pictures successfully with different lenses and a mobile phone camera. Pictures were then collaged into 4 quadrants:
a. Top left: mobile phone camera
b. Top right: telephone lens at 200mm focal length
c. Bottom left: 50mm standard prime lens
d. Bottom right: 28mm standard prime lens
Naively did I think an easy job of getting a clear shot on its stigma and style with a telephone lens at 200mm focal length, instead I was having a real difficulty and proven wrong, neither switched the lens to a manual focus did not overcome the same problems. The telephoto lens has its optical and mechanical limitation which, I believe, can neither be resolved nor be done by sharpening in photo editing applications. There is another feature of a telephoto lens is the background of a picture gets milky and blurry, as a focal length gets longer with the compression starts to play a role - the subject stands out from its blurry background.
Now, the standard prime lenses, 28mm and 50mm focal length. Due to their respective MFD of 300mm and 390mm, they have failed to fulfill what a macro photography is. However, I received a clear shot on its stigma and style but not milky and blurry background.
Last, the mobile phone camera. As we know a mobile phone is convenient, versatile and always Internet-connected while its AI-embedded features make camera/cameras is/are able to simulate an aesthetic beauty and a great depth of field at your fingertips. From the picture, wouldnโt you agree it stands out much better edge than the previous lenses mentioned from the above, I shall firmly say it can be the next best alternative device in the absence of an actual macro lens. We would have little difficulty of blurring its background with a few button clicks during photo editing.
Under a well lit ambient, a mobile phone camera is a wind sweep winner without say. Having said this may I say every DSLR lens has its discrete functionality, exclusivity, usability, applicable and adequate to a scenario (such as portrait/sports/landscape/architects/night view/macro) - there are no 100% all rounder lenses served for all purposes.
