BEJO Photography: Big Result in Small Package: Olympus M. Zuiko 45mm f/1.8

Hello everyone, I want to share a little bit of my experience on Olympus 45mm f1.8 lens that I love so much. I primarily want a light and portable lens that can cover a mild telephoto focal length with large aperture for shallow depth of field and low light performance. This lens is the answer.

I mainly use this lens for portrait that requires a bit of reach. But this lens doesn't only do portraits; it excels on other things such as tight landscape, street photography, architectural photography, close ups, and many other genres of photography. At this focal length, the depth of field produced by the lens is already quite thin for my taste and you can get some serious creamy bokeh from this lens without putting too much effort.

Let's dive in, what's good from this lens?

Technically speaking, the 45mm covers an equivalent of 90mm in full frame term, which is in the range of the sweet spot of many portrait lens such as 85mm, 90mm, and 105mm. On full frame terms, those lenses that I mentioned will definitely be big, heavy, and expensive. The opposite is true in the Micro Four Thirds world; the Olympus 45mm f1.8 is one of the lenses that embodied the "Spirit of MFT" in which the lens is small, very compact, lightweight, and not terribly expensive, but it delivers sharp image quality, punchy contrast, good autofocus performance, and adequate build quality.

This is one of the smaller lenses available for Micro Four Thirds. You can carry this lens inside your jeans pocket or jacket pocket and take it out only when you need it! It's not a pancake or anything like that, but still it is very small and surprisingly can always be carried in your camera bag without taking any space significantly. Combined with a small body like an E-PL6, you will pack a big picture in a small overall package.

Talking about image quality, it is just as sharp as you can get for a lens at this category. At f1.8 it is already sharp, stop it down to f2.0 it is a bit better, stop it down further to f2.8 and it is at its maximum performance. Take it down further to f4.0 and the sharpness improves only slightly from f2.8. I use this lens without hesitation at f2.0 most of the time and I know that I can extract a beautiful picture out of the lens.

I tested the hell out of this lens by shooting all kinds of tree leaves and branches from all sorts of distances and I can't seem to find any chromatic aberration in this lens at all aperture setting. I was not expecting it to be this good! Even the mighty 75mm f1.8 has chromatic aberration and this lens easily put that monster down to shame in the chromatic aberration department.

Autofocus is fast and instantaneous, just like the 75mm f1.8, the 17mm f1.8, 25mm f1.8, Panasonic 12-35mm f2.8, Panasonic 14-140mm, and many others. In fact, there are only 1 lens that has slow autofocus in the Micro Four Thirds department and that is the Panasonic 100-300mm.

Price wise, it's definitely less than US$400.00 which is crazy cheap for a lens that is 90mm in full frame term. You can definitely go to a more pricey option in this category by choosing the 42.5mm f1.2 by Leica Panasonic if you really need f1.2.

A couple of note that you should know...

Though this lens is already classified as a mild telephoto lens, the lens proved to be more flexible compared to a more serious telephoto prime such as the 75mm f1.8. However, please note that this lens doesn't focus as close as the 17mm or the 25mm. In fact, it won't do any good for any kind of macro photography unless you have a specific lens attachment for macro or similar device.

Also please note that this isn't the best lens for headshot although you can do it with this lens and get a good compression(heck, I sometimes even do headshot using the 25mm). I would suggest at least 60mm focal length in MFT for headshot as the compression starts to really help to flatter the image significantly.

Final thoughts

This is one of those "must have" lenses in the MFT world. I personally love this lens and I use it a lot for different purposes and this lens never fails to deliver the best result for a mild telephoto work. If you need a mild telephoto lens for your kit, then look no further.
