The Best of the Legacy 28mm Lenses

The Best of the Legacy 28mm Lenses

A last image from the 28mm lenses. I've included a Nikon image here to compare it to the Olympus OM 28 f2.8. This image isn't actually all that bad (one of the few). You can see that the Nikon meters slightly darker on the Nex cameras. It's equal to the Olympus here, so if you do manage to get a good copy, it'll be a keeper.

The bottom two, again from the Sigma and Vivitar lenses are comparable. I really can't tell the difference between them so it doesn't matter which lens you select here so it's just on ergonomics. If you enjoy using one lens over the other, just go for it.

Now, why aren't the Sigma and Vivitar lenses from the same manufacturer? If you look carefully at the above image, you'll see that the Sigma seem a little wider than the Vivitar. You can see the cobblestones in the Sigma image where they're nowhere in sight in the Vivitar image. I must stress here that I was standing in the exact same position when taking both images. Also there's a little bit more to be seen on both left and right side of the image from the Sigma lens.

The Best of the Legacy 28mm Lenses

I thought I would post a compilation of 4 images showing the results from 4 different lenses. I've left the Nikon 28 f2.8 out because of the poor performance of the lens. I'll repeat here that the poor performance was due to a bad copy of this lens, and if you should purchase a good copy the performance should be up there with the best. My 50, 100 and 135 E Series Nikon lenses perform very well indeed on the Nex and m4/3 cameras.

Opening the image to full size it's easily visible that the Pentax Takumar (top right) has the best rendition and sharpness of all the lenses. The colour is also better to my eye but this is easily corrected in post.

The Olympus OM 28 f2.8 came in second (top left). These 2 images were taken just seconds apart.

The bottom 2 images taken with the Sigma and Vivitar lenses were taken several days later so the lighting is a little different. Both don't come close to the Takumar. They do however, look so similar that I would have said the lens is from the same manufacturer, but I don't believe this to be the case. Why? I'll post the reason tomorrow.

I really enjoy using legacy lenses on either the m4/3 or Nex systems. At present, Sony have implemented the "peeking" function as an aid to accurate focusing using these lenses. I find it a lot better than using it on the m4/3 system. I find that it gives me real accurately focused images while I do struggle a bit with the m4/3 system, especially with longer focal lengths.
The E-PL1 is my favourite camera for this use from all the m4/3 sytem. Right now you can purchase these for next to nothing but the image quality is really amazing. High ISO is not great but I really don't use high ISO all that often, actually hardly ever so this small camera is pretty ideal for my use. I hope Olympus brings out a firmware upgrade that implements the peeking function found in the Nex cameras. That would make it even more fun than it is now.
The 2 lenses seen in the image are relatively new and they haven't really been tested yet. I hope to get out with the 100 f2.8 in the next few days and I'll report back on how it handled.

This is the reason I don't use the Ultron 35 f1.7 much these days. It's the Voigtländer Nokton 35 f1.2 II lens. It really is a beast, heave but built like a tank. You get the feeling it really is undestructible. Since I was purchasing this not really cheap lens I also purchased the Voigtländer adapter to go with it. It just fits in beautifully with this lens and everything works as it should. A fantastic lens to use and renders the images quite like the Leica magic you see in some images.
If you're after a bright lens for your system in the 35mm range, this is the one to get. You won't regret it. Worth every penny.
Talen with an Olympus OM 100 f2 lens mounted on the Olympus E-Pl1.

These are some of the smallest lenses that I have evr used. They really are tiny but perform beautifully on the modern cameras offered. You can get all three of these pretty cheaply on the net, only the 40 f1.4 will cost you a couple of hundred. Many will ask themselves why I have so many lenses and the answer is I just like beautifully crafted things. And since photography is my hobby I like to collect these lenses. True I can only use one lens at a time but when I go out, depending on type of mood I'm in, determines which lens I will take. On the Nex cameras I tend to use these small lenses because the Nex-5n is a really small camera. It just makes for a very small system that produce some stunning images. Of course, if the images aren't all that good is entirely the photographers fault i.e. Me. Each lens has it's own character and renders the images quite differently.
So if I like well crafted things why don't I collect Leica lenses some may ask. Easy answer: I just don't have a 100k laying around the house.
These lenses produce stunning images that are really good enough for me.

A side view of the Heliar, Ultron and Nokton lenses I posted yesterday. Some of you might have been wondering what they really look like. That Nokton does seem fat doesn't it, but only because the other two are really slim...really. I might just post some images of these lenses mounted on the Nex or E-PL1 cameras just so that you can see how small they are. The Nokton is the heaviest of the 3 lenses and is one of my favourite lenses.

After a little sorting I realized that I have some nice Voigtländer lenses the some of you might not know about. The first 3 are the Heliar 75 f2.5, the Ultron 35 f1.7 and the Nokton 50 f1.5. I've shown a number of images from the 75 and the 50 and I use then quite a bit on both the Nex and m4/3 cameras. The 35 I don't use a lot and I'll explain why in the next couple of days. Most of these lenses cannot be bought new anymore because they just don't make them. They have been superceeded by newer models but that doesn't mean that the newer ones are better than these models here. Both the 75 and 50 perform very well on the Nex and having fokus peeking is a major plus on these cameras. I use my E-PL1 mostly for manual focus lenses in the m4/3 camp because I find it easier to focus than on the other models.

After posting an image of the Panasonic lenses yesterday I thought about what else I have in the drawers about the house so I started sorting things out a little. Today I'm posting an image of the different 135 f3.5 lenses I have. These are relatively small and very useable when mounted on m4/3 or Sony Nex cameras. The smallest and lightest of these is the Minolta and is a beautiful lens to look at. The Konica lens is heavier and I think this is the one I least like to use. It's not in same league as my other 135 f3.5 lenses, or it could be just my copy. The top 2 in this range of manual 135 lenses are the Olympus OM and the Pentax SMC. Very nice build quality and the image rendition is really fantastic. The Pentax is quite heavy and feels quite undestructible. If you want a nice 135 manual focus lens for your Nex or m4/3 camera, look no further.
If you're wondering what lens I used for this image, it's an Olympus OM 28 f2.8 mounted on an Olympus E-PL1. Still a great camera for manual focus lenses.
