This image shows just how sharp these prime lenses really are (mind you, I've seen some terrible older lenses so make sure you get a good copy). I stopped the lens down to f4 for this one. Note also the smooth bokeh you get. Some prime lenses tend to give you busy backgrounds, especially if you have some branches in the background but not this lens though.

When looking at images like the one above, I realise why I like using these long manual focus prime lenses. It has a quality that I find hard to get with the modern AF lenses. Apart from that, at the time of this post you can't get a prime of this focal length for the m4/3 system. Panasonic have stated that a 150 f2.8 is due out in 2013 which makes it a 300 f2.8 equivelent. Nice, but it's going to be quite expensive I think, considering the price of their 12-35 f2.8 and 35-100 f2.8 lenses. I'm actually considering the Olympus 75 f1.8 lens which gives me the equivelent of 150 f1.8 lens because the images I've seen from that lens are really really nice. Time to save up again I think.

The reason I like using lenses of this focal length is that it gets me closer to places that i can't get to normally. Take the image above, I was not able to get all that close to it and the 135 brought it to me. I saw what I wanted to get and this was the perfect lens for it. I also had the 100 f2.8 with me but that didn't get quite what I was after. I'm just wondering if the 135 f3.5 would have gotten me the same image. Probably not quite but it would be damn close. The perspective would have been the same but what about the aperture and that fern in the background.

Note the shallow DOF in this image. The pistils are sharp but the rest of the flower is not. That takes some skill to get on the first shot (which I didn't by the way). It took me around 5 attempts to get what I wanted. I took so many frames because I really wasn't sure I had the shot after looking at the images on the LCD. That's one reason I also don't delete the images in camera. You really can't tell what you have until you download them onto your PC/Notebook and look at them closely.
