Lessons learned with my first manual lens on DSLR

I recently bought a manual lens on ebay. I saw some pictures taken with a manual lens on flickr and got curious. Some minutes and EUR 88,- later (USD 125,-) I was the owner of a Revuenon 55mm f1.4, an adapter for the M42 screw mount to EF and a lens hood.

The first impression was heavy. This glass is built like a tank. Metal everywhere. Great! And the aperture is 1.4 so it is fast. The DOF is shallow. So the first tests were on how the glass reacts to bad lighting and how to operate the little gem.

So the first thing I learned: Take your time.

In some light conditions it is fairly easy to focus with the view finder, but especially if you are close to the object it is better to us the liveview. The DOF is so shallow that it can be the trickiest part of the whole procedure to focus.

Once I knew the signature of my glass I took it for a walk. And I had fun!

Feet of steel will show you, that the DOF is shallow! Recognize the small strip of sharpness on the ground. Small details like this can be useful when focusing by hand. Read more

Still trying to master the 1.4 with manual focusing on my 60D. It seems bad to focus with the liveview. I have seen some good shots and some bad ones but it still hits me like a hammer how shallow DOF can be. The focus lies on the second row of dots on the black die and does not really reach the green one. This is a wonderful and mean piece of old glass 🙂

Low budget macro photography

Did you ever want to create one of these gigantic macros without cropping your pictures? It is only a question of time until you find mentions of a retro adapter. A retro adapter is a adapter attached to your lens so you can use it the other way around. The adapter fits the end where you use to screw your filters onto. I have a protector for the now open end of the lens.

The principal which comes to use is that…   People who know me, expect at least 1460 words of scientific conundrums and several links to wikipedia and wolfram. Not here! It works. This is all that matters. So I started to have a look at the tips of my beloved aquarel  pencils. They look like this:

Tips of Coloured Pencils

Do you see the problem? The highlights are blown out, because I had the problem with the lighting. You can see the harsh shadows due to the additional light of a fenix LD20 in burst mode. What you also see is the very shallow DOF (see also Two acronyms in photography you should know). So you can imagine the following: Me, trying to focus on the tips of the pencils holding the camera with both hands, trying hard not to breath andgiving instructions to the very patient woman in my life. Please higher my dear, to the right, more, less,….  I bet her secret middle name is patience.

So I searched the web and tried to find the solution for the shallow DOF and here it is: Read more

Two acronyms in Photography you should know

People who look at my flickr stream mostly ask what these acronyms are because they are seen often in photography:

DOF: meaning “depth of field” and providing you either with sharpness in every detail or just a range, hence often called shallow DOF.

The fist

POV: meaning point of view and speaks for itself

Killing field

What are your favorites?

It is said that it is a good thing for a photographer to use prime lenses. The funny thing is that I was planning on doing something absolute different, which is another project.

What is so different when using a prime lense? The difference lies not only in the elimination of the variable zoom. It is also the emphasis on the composition of the picture and the variables DOF (depth of field), focus, aperture and shutter speed.

Finally you will realize that the zoom is still there. Your legs and arms are the zoom.
