Question on dslr macro lenses.

Post Thu Nov 30, 2006 1:47 pm

I'm trying to understand dslr macro lenses.

Some background and information leading to my question: Many years into the AARP group, I started shooting about 4 years ago, and in digital. Have been using P&S zoom cameras (Panasonic FZ series) but have gotten very interested also in macro photography and use add-on third-party lenses such as Olympus MCON-35; Nikon T-6; Nikon T-5; Raynox CM-2000 Macro Explorer 2.5x (8 Diop) & 1.5x (4.8 Diop). I do not hesitate to stack the macro lenses for real small subjects at what I like to call "micro". Here are a few examples. Some are right from camera and some sharpened with Picasa (extent of my editing skills at the moment).
This one taken with T-6 and T-5 stacked -
All the following were shot with three stacked macros; the Nikon T-6 + T-5 + Raynox 2.5x for about +12 diop. total on tripod. I don't know what this diop equates to in magnification? Anyone?
Smaller still; hand held, heavily cropped and many many dozens of shots to get two good ones.

Considering getting my first dslr; My Question. ---
In the dslr lens world, what lens or combination would provide this type of magnification??
Also, am I correct (or not) in thinking that a 100mm macro lens allows the photo to be taken at a greater distance than a 50mm macro lens but not any greater magnification??

I have several galleries about the basics of shooting macro, that might be of interest to you here:
You should be able to find most of your answers. If there's something not clear, pmail me and I'll get back to you. :wink:

Are you trying to make us guess your age? :)

To answer your question...if you use the same equipment as your old camera, you'd get a little more magnification. I've tried using the Kenko extension tubes stacked together and the subject is noticeably bigger. However, it doesn't seem to be 1.5x bigger though.

I shoot a lot of macro. I'm no expert, but here is my advice.

Extension tubes are great (and i use them), I do not have 2 lens with the same diameter at this time or i would be doing that (because its better).

Here is my set-up.
70mm Macro + 2x Teleconvert + 54mm of tubes. Why the 2x Teleconveter, because it allows me to be twice the distance away, end of story (same zoom).

I provide two picture to show what they can do, now this is not Micro (Even though Nikon Says it is :roll:). Unfortunally i don't have the lens specs handy for what level they are, but on my computer screen (totally accurate method) the first is 2 inchs across, the second is 9.5 inches. A canadian penny is the same dimentions as an american penny.

70mm Macro Only

70mm with 2x & 54mm Tubes (8 inches of lens on the front of the camera)

Its more then 1.5x for sure.

What you need to look at is called the Maximum Reproduction Ratio for the lens you are using 1:2 & 1:1 are considered macro with 1:1 being better. You being moving into "micro" territory when you begin to get 2:1, 3:1, more detail then the eye can see.

Here is a list of Nikon's Current Lenses (Cause I knew where to find it)

FYI: Just a quick note on the 105mm VR offered by Nikon. I have used it. it is a great lens except it has a lot of travel when using the auto focus (which is why I try to focus manually whenever possible), this is because it trys to focus from the ref point to inifinity and back untill it locks. Which is a problem because often the focus point is closer then the reference starting position because you likely just moved closer to your subject. Great design for a telephoto, however how often are you moving away from your subject in macro?

Thats my 2 cents worth,

This photo was taken with a Canon A630, a point and shoot camera:

Most of my marcos in my gallery were taken with the Nikon D70 and a 70-300mm zoom lens in marco mode.

I have three extention tubes that I have sometime used.
But the depth of focus is so shallow that it makes getting a really good picture very difficult.

On the other fhand I took this one:
using the D70 with the 70-300mm lens and a 12mmET.
This image is greatly enlarged from the orginal.

Both images have been cropped square in PS.

Here is the bug orginal image:
So you can play aound with image size and greatly improve the picture.

Thanks to everyone for help.

Thank you to *all* for information or sources of. And thanks to dang for all the info on his site.

I don't think I'll have much trouble when I do get a dslr. Until then I'll keep experimenting with my Panasonic FZ30.

From this - see the black spots on the leaf. They are a plant pest called a thrips.


then stack some closeup lenses for this (yes thats a dead fruitfly)

and good enough for cropping - note the reflection in the drop of liquid. BTW - handheld.
