Extension tube with wide angle lens.

[EBmedia]

Hi everyone, last time i like wide angle macro work, and trying to get in to that world, just don't want to spend money to buy new wide angle macro lens for example (Laowa 15mm), but i have Nikon 16-35mm lens and thinking to adding extension tubes to get better magnification and close focus distance. So dose anyone has some experience with this set up, just interested will this work ?

I think the best you can do is try different combinations, I've never tried a wide angle lens with extension tube. Instead, wide lenses (especially at 28mm) are far better is they are mounted inverted using an adaptor.

I've read some articles but I'm still not sure if this can work.

Your above mentioned lens 16-35mm from Nikon (AF-S NIKKOR 16-35 mm 1:4G ED VR ) has a magnification power of 1:4. This means that a bee of 2cm would have a size of 5mm on the sensor at the minimum focus of 29cm.

To reduce the minimum focus you can use such extension tubes which allows you to come closer to the subject and get a higher magnification. But to get 1:1 magnification (2cm bee = 2cm on your sensor) you would really need a long extension tube and have to come so close to the subject, that I'm not sure if you can handle this anymore. I've also read an article that an extension tube length above the focal length won't work. But I'm not sure about that.

So at the end I don't think, that you can really use your 35mm lens as a real macro lens. And even if it would work you would reduce the DOF in such a wa, that the background becomes much more blurry than before which means that you'll lost your desired effect.

But again... I'm not really sure if everything is correct what I've written and I've understood everything correctly.

Hi thanks for answer, but this is idea to use wide lens for macro not blur the background, and show the insect with nature surrounding, this is how Laowa 15mm macro lens works, minimum focus distance on that lens is 122mm from sensor and you right it's touching the lens. And this is not easy think to take shots like that, special for the lighting as you blocking the light most the time with the lens, this is why i want to try cheaper way and see how it's working. Laowa 15mm macro cost around 500$, extension tubes is way cheaper in case if i don't like what i get.

I know this way, but you limited to one focus distance with this combination

You probably know, you get for what you pay . Maybe you can check with Laowa website, if they refund your money in case your aren't happy with results.
