First Macro with Laowa 7.5mm on m4/3

This is marketed as “World’s Widest rectilinear f/2 lens for Micro Four Third cameras.” It has an angle of view of 110 degrees, the same as for 15mm on full frame (but it is minute in comparison with the bulky 15mm lenses. It is only just becoming available. I placed a “pre-order” for mine at the end of May and received it last week

The minimum focusing distance of 12cm seemed useful for this subject, which was growing on the vertical side, inside a black plastic garden compost bin. This location is challenging for getting camera, lens and flash in position. On this occasion, I used all three flash units off-camera, positioned on the top of the organic matter in the bin. The main unit zoom was set to 12mm.

I had to use the rear screen of the camera tilted upwards at right angles.

Apart from the viewing angle, I experienced the same hesitation with focusing the ultra wideangle lens that I used to in my films days, then using such lenses rarely. This was my very first time for anything remotely macro. The lens is one of two, the other a Laowa 12mm, which are to restore the angles of view, and rectilinear images, on m4/3 that I loved with 35mm film.

The lens was set at minimum focusing distance for most images, at f11 for all. The colony in the second image is ca 7 inches/180mm wide.

Several of the images have been cropped vertically, some less so but horizontally.

At my first attempt to load these images on the host site, the system rejected the files as too large. I had to re-save the images as quality 8 instead of my usual 12. That shows how much detail was captured. It is years since I had to do that.

Update:

22 hours later, that extensive network in no longer visible to the naked eye and the organism seems to have retreated into small, pinkish bodies, which can just been seen to be forming in these images.

Interesting result Harold. I would be interested how it performed reversed for ultra macro using this https://www.amazon.co.uk/Fotodiox-Re...+reverse+mount

My 4mm Apollo TV lens in c mount works well, but the distance to subject is very short.

For a long time, I wanted a 4mm lens to do some utlra wideangle macros. The Laowa 15mm Wideangle gets me a long way there.

As the 7.5mm has no issues about diaphragm control when reversed, it may be worth a go. Protecting the exposed rear element will be a concern, as will working distance.

It is something worth trying but not with active subjects.

Thanks for the link. They had only 2 left and there were none on Ebay, so I bought one.[/url]

It arrived yesterday. I don't expect it will do much useful directly on the camera but I have extension rings. I will have to wait for suitable subjects. It won't be flies!

Re: First Macro with Laowa 7.5mm on m4/3

Thank you Harold. Just waiting for your full review from using it in the field (i.e. non-macro). Some pictures of the lens on the camera would be nice too if you are able.

Re: First Macro with Laowa 7.5mm on m4/3

Hi this lens is very appealing to me from the landscape point of view, I'd love to see/hear your view covering this if you wouldnt mind.
Much appreciated

Tim

I haven't been out and about with it (or with the 12mm). I understand there is a lot of interest with stargazers.

I used to use a Tamron SP 17mm a lot with film and this is a bit better for m4/3. Likewise, the 12mm, hopefully with the Magic Shift adapter, when they launch it, is the equivalent of my 24mm shift for film.

This topic may be of interest:

My 4mm Apollo TV lens in c mount works well, but the distance to subject is very short.
I did some shots with it reversed onto the body. Approx values:m FOV 4mm wide, WD ca 12mm.

The results look good but it is impractical for most small subjects as it snags the substrate.

The benefit of the Apollo being the c mount which is small in diameter and allows a shooting angle of about 30 degrees although the DTS is less than 12mm. I can now get to that mag with the teleconverters on the Oshiro and a working distance of 40mm.
