Sony Alpha A7 - Pentax M 135 f3.5

Sony Alpha A7 - Pentax M 135 f3.5

Although the branch with it's berries is quite sharp and, for me, quite pleasing to look at the problem with the f3.5 lenses is obvious to see. I thought I has enough background separation here to render is smooth. Well I didn't although it was quite aways away. I'm certain an f2.8 or f2.5 lens would have rendered this much better than the f3.5 lens. But those lenses are a bit larger and heavier than these little f3.5 lenses. For some people the above image would not make the grade and a faster lens would have to come into play. For me however, it's good enough. Notice I'm getting better at this manual focus stuff.

This is one situation where the bokeh is aceptable although the backbround isn't all that busy. Again taken wide open and close to MFD I still managed to achieve what I was after. Practice really does make perfect and I shall continue to practice as often as I can.

Sony Alpha A7 - Pentax M 135 f3.5

I took this image to test 2 things. My manual focusing skills and to see how bad bokeh is with this lens. It was taken wide open at f3.5 and is sharp enough for my purposes. Bokeh is another matter, being a little bussier than the Olympus 135mm lens but can, in certain situations, be very good indeed. I find this little problem to be a Pentax characteristc with the manual focus lenses. The faster Pentex lenses may be different but my faster Pentax lens to-date is f2.8.

Sony Alpha A7 - Pentax M 135 f3.5

Sony Alpha A7 - Pentax M 135 f3.5

Now for a few Pentax 135 f3.5 images. For me personally, winter is a time when my photography slows down somewhat. I much prefer all the other seasons to this one mainly because of the bleakness of the landscape and there is a real lack of colour. I may like monchrome images but I tend to see in colour. I'm sure there are people out there that can identify with this.

 

I really like using the Pentax manual lenses because they really handle well and the construction is tip-top. It is also one of the smallest 135mm lenses available. I'm starting to ask myself if I prefer using these lenses on the Alpha cameras or on the Nex system. Presently I prefer the Nex system but that may change. I still have to get used to these cameras and I'll have to take a few thousand images before I get to know the Alphas well. That is a statement for all new cameras. Anybody that returns a camera after a week or so use and having only taken a few hundred photographs are making a big mistake in my opinion. Having said that, a camera might have a big flaw in it for some people which they know they can't get over. Understandable. The only camera I returned was the Panasonic GX7, not for any major flaw but because the EVF wasn't centered or was faulty. I just couldn't get the EVF sharp from corner to corner. If the center was sharp the corners were not and vice versa. Otherwise it was really a nice camera, small, responsive and it really fitted well in my small hands.

 

What attracted me to the above image was the moss, being backlit and had a certain glow to it. I think this image is a little small to see but I can assure you, seen at full size it's much more prominent. Contrast is a little low which is something often encountered with these older lenses. The sun was just out of frame at the top of the image.

Olympus E-PL1 - Pentax 135 f3.5

I find it really fun to use these old legacy manual focus lenses on the m4/3 cameras. It makes me want to go out and photograph. It really doesn't matter what you photograph, just go out and do it. The more you photograph the better you will get at training your eye to see things you normally don't. If you don't know what this lens looks like here is a link to it on Pentaxforum: SMC 135 f3.5.

It's small and although a little on the heavy side because of the all metal construction, handling it is not a problem. Image quality is very good as you can see in the above image. You can get these on ebay for little money and I'm sure it will give you a lot of pleasure in the months if not years ahead.

Last image from this combination for now. I've made a little compilation at a higher than normal resolution so that the individual images can been seen at a reasonable size.

Sony Nex-5N - Pentax M Takumar 35 f3.5

Another Takumar lens from Pentax. A couple of weeks ago I posted some images from the Pentax Takumar 28 f2.8, and that lens seems to be the best of all my 28 f2.8 lenses. I'll be keeping that lens and the rest have to go. I have one test still to do and that is between an Olympus OM 28 f2.8 and a Nikon E-series 28 f2.8. I've heard some good things about both lenses and the images I've seen posted have also been spot on. It might be that I'll be keeping all three but we'll see after the final test which shouldn't be long in coming.

The Takumar 35 f3.5 has good build quality, actually it can't get much better and they don't build them like this anymore. It's an all metal lens which is quite heavy in the hand but manageable on the Sony Nex-5N.

Another couple of images from this combination after today.

This is the last image from the Takumar 28 f2.8 for now and I hope you have had an insight into this wondeful lens. I will be keeping the Nex-5N as well as I think it's ideal for using these legacy lenses. Again, if you haven't tried a Nex-5N, see if you can get one from a photographer friend or rent one for a day, I think you'll be surprised at the image quality.

I have a lot more images taken with this lens so instead of posting one image per day I've decided to compile 2 or 4 images together as a single post. I hope you find this better than posting too many images from a system one per day. I'll be doing this more and more in the future as I think it gives you a better idea of the quality one can achieve with these lenses. One more to come after this one today.

The image above is one of the best renditions I have achieved with any of my lenses. All I can say is that it's excellent and I can only astound when looking at this image at 100%.
