200mm with a Marumi Macro 3 lens attached.

200mm with a Marumi Macro 3 lens attached.

I got a new set of filters today, 3 Marumi filters: a +3 macro, a circular polarizer and a neutral density. After looking at all of them I immediately put the +3 macro onto my lenses to try it out in my backyard.

At first I tried it with a 50mm f/1.8, I could focus a lot closer to the lens but the region I could focus shrank a bit. It was small to begin with. If I was shooting still objects they photos would have come out sharper with a better focus. However I was thwarted by a light consistent wind.

Then to try out the extreme I put it on my 55-200 VR lens keeping it at 200mm. The focus distance went down from about three feet in front of the lens down to a foot or so. Again the focus region was small but this lens had autofocus. Or at first I thought that this would make it easier, the AF for either the lens or the camera body (D6o) was slow and not very good with macro. I quickly reverted to manual focus (except when trying to shoot moving bees).

The image quality was alright. For the 50mm it was pretty good, not as sharp as it usually is but not bad either. At 200mm it is not that sharp and there is a lot of soft glow spread around the image. The images at smaller focal lengths did look better and I only practiced in direct sunlight. Though I feel that there might not be enough light to use the +3 lens by hand without direct sunlight.

I don’t have a dedicated macro lens or any other close-up lenses to compare this Marumi lens with but so far it has been fun to play with. I don’t know how I will use it in the future or if the images will be sharp enough (maybe I should not do 200mm?) for decent macro photography.

Festive masks for the season.

Festive masks for the season.

 

A week ago I finally received my belated birthday gift (belated as it was not released yet) a LenBaby Composer. A Lensbaby is a prime camera lens that rotates in a ball socket, instead of having a plane of focus there is a movable spot (sweet spot). Because of the rotating and unusual focus it is a manual lens without a CPU. The lack of a CPU translates to manually setting the exposure (no exposure metering in the camera).

After a week I find that it is a fun lens. While certain subject appear dull with a normal lens my Lensbaby allows for a new take on the same subject. What’s more it brings out a higher degree of creativity. My particular lens is 50mm so aside from the unique ball socket and manual exposure it is the same as my loved f/1.8 50mm lens. Except that the Lensbaby has a maximum of f/2.0. 

Aside from finding the “sweet spot” choosing the aperture is also unique. Normally a lens has a small computer inside allowing for the lens aperture to be set by the camera or going furtyher back there is a ring to set the aperture. This lens has neither. Instead the aperture is set by physically changing out the aperture ring. The rings are made from a semi-soft magnetic material that is held above the lens by three magnets. The lens comes with a small tool that holds the rings with a magnet on the back switch them out.

This may seem like an inconvenience and it would be if you were shooting in continually changing lighting conditions or fast subjects. However I feel that for the most part this type of shooting is not the target of a Lensbaby. What it does allow is for custom apertures. The background blur of a photo is caused by the focus but the shape of the blur is determined by the aperture. That is why some lens produce certain pointed stars. Kits are sold allowing for custom made aperture disks, but I thought it can’t be that hard.

With tools at my disposal I took some post-it notes and a knife and jury-rigged some test apertures to see what would happen. Because I used purple notes that did not block all light a slight purple tint invaded my test photos. Here is how my purposefully out of focus Christmas tree came out:

So far I like the lens. I am not yet fully versed in how to use it, that will come with practice. I still find it funny that my lens acquisitions are in a way slowly regressing in ease of use. First I had autofocus VR lens, then a prime non-VR manual lens and now a Lensbaby that lacks exposure metering (with my camera at least). And yet it is the simple lens that are spending the time on my camera.
