Macro Photography Lens Solution

Sunday, January 25th, 2009

Last time I talked about understanding macro photography technique and composition, therefore I now present the variety of lens solution that you can use for macro photography. The range of solution varies a lot with image quality and price range (as usual).

If you own an SLR Camera and an existing lens:

You can use magnification lenses for macro photography if you already own an existing lens. This is by far the cheapest possible solution to get macro shots.

Magnification Lens

The amount of magnification with this lenses varies with their power. The bigger the number the stronger the magnification. In the image example above I have the +1 lens coupled with a +3 lens which makes up to +4 magnification.

There are trade-offs when using these lenses however:

  1. The more magnification lenses you put in front of your lens, the less light getting through the lens. Which means your camera speed will be lower than normal. Say in a certain condition you have 1/100s speed, when you screw on these lenses you might end up with 1/60s speed.
  2. The depth of field will be shallower than a true macro lens. With these lenses its slightly harder to get the background of the object sharper without losing the speed.

As I said previously, this is the most affordable quality solution.

If you are planning and have the budget to get a new lens:

Dedicated Macro Lens

Dedicated Macro Lens

Then get the true macro lens. These lenses offer very high magnification and incredible detailed result. Depending on your budget, you might want to look at third party providers as well. I use Tamron macro lenses myself and to date I have been very satisfied with its results.

With this lenses, you will have full control of the aperture, speed and focus. Many of these lenses have fixed focal lens, meaning that you will not have an option to zoom in or out. That’s okay, considering you don’t get that far or close from your macro subject most of the time.



If you want to get a semi-slr:

Macro in Compact Camera

Don’t forget to consider and semi SLR camera with macro capability. My old DiMage A1 did very good macro before I switched to the SLR. It gave good details when printed up to A4, above A4 however we might start to see the compression noise. This is because of the nature of Semi-SLR that has smaller image sensor than the true SLR. Ont he other hand, as technology grows, the semi SLRs are getting better and better in its quality. Best way to find out is always to check out the sample shots for a particular camera.

Reverse lens technique:

This a technique that can also be explored if you feel adventurous. Basically you use the other end of your lens to be attached to the camera body, then you will get massive amount of magnification. Of course you will have to buy the converter to do this. The downside of this technique and why I never use this as my permanent solution is that you might get your bottom end of your lens (the body connector part) scratched.

As you can see, there are a lot of ways to start doing macro shots. I wouldn’t recommend those macro settings in a compact pocket camera however because of their lack of control and their depth of field is never shallow enough.

Rv has a new gear!

Front View - Tamron SP AF 90mm F/2.8I have finally obtained my new (power) toy, a great addition to my camera’s family. What I have here is the Tamron SP AF 90mm F/2.8 Macro 1:1 lens.The first thing that I can say about this lens is that this is a real “value for money”. Some of you might ask why not get a Nikkor Lens (Nikon Lens)? Well I guess we all know that Nikkor lens cost a whopping amount of cash and seriously, sometimes the quality difference between a third party lens like this one and the Nikkor is so little that I consider it arbitrary in some circumstances. After all, it’s more on the photographer and not the gear to get great images.

So what can we expect from this lens?

Sample shot of the macro lensFirst thing, this is a 1:1 Macro lens, meaning that it is capable of creating 1:1 image reproduction of the actual object; although if the “limit switch” (not shown in this picture) is turned off, you can get much closer than 1:1 scale. I have been testing this lens for a while and quite please with the resulting images, the depth of field is great and the sharpness of the resulting image is very pleasing. On the right is an example of a necklace pendant taken using this lens under studio lights.

More on the specs…

Rear View - Tamron SP AF 90mm F/2.8 One of the most important spec is the focal length. This camera came with a fixed focal length at 90mm, meaning there’s no zoom in and out. Some might disagree however I think when I’m photographing outdoor with this lens for non product object, such as a person, it forces me to be more creative and to make the most out of the available space at the time of the shoot. So with this I can also say that this lens is not just for close-ups, instead can be a great companion for a portrait shoot.

Another interesting aspect of this lens is that availability of a manual aperture ring, a feature that is not very common in the era of digital, in particular with less-expensive lens like this one. Of course with the digital SLR camera the ring is not being used very much however with my F-801s film that does not support electronic aperture ring, the manual ring is a handy addition.

Lastly and handy

Hover View - Tamron SP AF 90mm F/2.8

The last prominent and most handy feature of this lens is the AF (Auto Focus) and M (Manual Focus) switch, in order to switch to and fro between those two, all I have to do is just pulling or pushing the focusing ring. Notice that you can see a blue “M” and white “AF” writing on the lens, that’s where the focusing ring would “clicks” in. So there’s no more fiddling around with the small on camera body AF/MF switch. This is especially great when taking picture and the auto-focus won’t focus properly.

So why is there any catch with the half price of Nikkor?

Alhough this lens is one of the sturdy lens, compared to the Nikkor it feels more plasticky and in addition the focussing speed is slower than the nikkor lens. However eventhough I knew these things existed, they didn’t threw me off my decision to get this lens. As long as it focuses well, takes 1:1 macro reproduction, able to productng clear and high quality image, its all good. The sturdiness at this point is enough for me, after all, I don’t intent to throw my lens to the floor.

All in all this is a great lens!

I have to say that I’m very glad that I get this one, and it’ll be useful for years to come :) So if you’re getting a macro lens, consider this one!
