My Old Russian 1000mm Mirror Lens Doubled

My old Russian mirror lens.

Russian MTO-11CA M42 mount mirror lens on Canon 5D mk II

Last year I purchased a 25 year old Russian mirror lens. It's a 1000mm f10 M42 screw mount lens, which is basically a telescope.

I've had a bit of fun with this lens, like photographing the Stroud Subscription Rooms and Ebley Mill from Rodborough Fort up Rodborough Hill.

I even took it on vacation with us and photographed a newly married couple with their photographer on the beach. Too bad their photographer was more interested in looking at the back of his camera than photographing them.

You're missing it! 
What this lens is really great at is photographing the moon. This is what I'd like to do more of.


Note: This image has been cropped a bit. 

Well on to today! Today I received in the post an old Tamron M42 screw mount 2x converter for my 1000mm mirror lens.

Old Tamron 2x converter, M42 screw mount. 

What a 2x converter does is double the focal length of your lens. So my 1000mm mirror lens will become a 2000mm mirror lens. Sadly it also reduces the maximum aperture as well, so this lens goes from a fixed f10 to something smaller like f20 (but don't quote me on that, I've not done the maths!) What this means is you'll need a lot of light to shoot in.

Luckily the moon has a lot of light! Sadly it's a cloudy evening. So before it got too dark I ran out and did a few quick test shots. These aren't great images but it will show you what this lens with 2x converter can do.

I took two sets of photos, both from our back garden and both using a 50mm lens (which is basically what you see with your own eyes), the 1000mm mirror lens and the 1000mm mirror with the 2x converter. All on my full frame 5D mk III. Here are the results.

First up, St. Lawrence Church steeple in Stroud from our garden in Rodborough.

2000mm
And finally the 1000mm with the 2x converter making it a 2000mm lens. Same church steeple taken from the same spot in our back garden in Rodborough. 

I did this again with the Randwick TV transmitter across the valley. You really can't see it in this first photo, but it's there in the centre.

 Then I swapped lenses and put on the 1000mm mirror lens.

You can clearly see the transmitter now.

2000mm

And then again with the 2x converter. Not only can you see the transmitter well now but you can see that there is quite a strong vignette around the image as well. I suppose this is inevitable on a full frame camera and I doubt would be an issue on a cropped sensor. 

So in conclusion I'm a very happy camper and can't wait for the next clear night to shoot the moon! :-D

(Note: shooting with a long mirror lens often creates odd looking bokeh (out of focus areas) in the shapes of little doughnuts. This can be an issue with some photos, or it can be a creative part of the image.)

A Late Lunch by the Canal

The Lock Keeper's Café in Stroud

Wow! What a week! I've had several jobs back to back and it's not over yet! I have another lovely job tomorrow and my eldest baby girl is coming for a visit! I feel a shopping and baking frenzy coming on! :-D 

This week I finished up a big family shoot and have been working all week on a commercial job in which I had to hire several models for. I've been working all day every day from early morning until the wee hours of the night. It's a good thing I love my job! 

As a reward to myself for all the hard work I've been doing this week, I walked down into town for lunch. It was a late lunch as I was working hard to get some images out for the commercial job mentioned above. Where did I go? The Lock Keeper's Café of course! I love this place, and it's right at the bottom of the hill from where we live. People are always asking me where it is so I'll tell you. From town it's the other side of the train station over by the Wallbridge Lock/canal. That's the Hill Paul building behind it in the photo above. Just in front of it is the Cotswold Canal Trust Visitor Centre in the old Bell Hotel.

There's no parking so you'll have to make the short walk from town to it. It's well worth the walk though! And soon the foot path along the canal will be open again. I'm so looking forward to that as I love walking along the canal. 

Usually on Fridays you'll find the Friday Forum crew here at the Lock Keeper's. This Friday everyone had something else to do, so it was just me, and I was late. But not too late! They did serve me some lunch. I usually have a ham, cheese and tomato panini with a cappuccino coffee. But today I thought I'd treat myself to something different, so I had one of their specials for the day which today was a Tuna Noodle Casserole. Yummy!

Today I had lunch alone all by my lonesome. I don't usually like eating alone and avoid it at all cost. But today down at the Lock Keepers it was quite nice. I did't feel all alone. I'm in there so often that the owner and crew know me quite well now. Also several people I knew were in and out and they stopped to say hi which was quite nice. 

I give the Lock Keeper's Café 5 out of 5 Stars! I highly recommend them for lunch or for just a coffee break with a friend. The staff are always friendly, the place is super clean, the food and coffee are fantastic, an over all lovely atmosphere. Oh and there's free WiFi and papers on hand to read. What more could you ask for? 

While I was there this little girl came for a visit. I couldn't resist asking for permission to take her photograph as she was just too cute! I had a talk with her father the other day and he said he'd be booking a family photo shoot with me soon. I'm looking forward to it. :-)

The low afternoon sunshine coming in through the large window on the right made for some lovely lighting and I waited until she was in this light to take her portrait. The two catch lights in her eyes really bring her eyes to life. The main light source being the large window I just mentioned above and the second catch light being made by the window in the door behind me. 

It's a shame about the window directly behind her head as this bright area in the photo is quite distracting. I burned it down some so that it wasn't so bright. I did notice this while I was taking the photo but there wasn't an immediate solution to the problem, not without loosing the lovely light on her face.

The above photograph has had some extra post processing done to it. I did not exactly invent this look all by myself but the technique I used I developed myself. What I do is after normal processing I create a black and white adjustment layer. I really push the contrast of the B/W image then I lower the opacity of the B/W layer by 50% letting some of the colour of the original image come though. You wind up with a lovely desaturated image. Well I think it's lovely, my husband prefers the original full colour image which is below.

(Please note: I know who the little girl is in this photo, I just didn't want to say who she was to the world wide web.)


On my walk home I noticed this sign by the canal. It tickled my funny bone so I photographed it.


CAUTION DEEP MUD
It's not every day you see this sign. Actually it's the first time I've ever seen it. If we'd seen a sign like this when we were kids you'd been hard pressed to keep us out of it. :-D In the background you can see the road construction continues up Bath Road in Stroud.

I leave you with a few photographs of flowers that I took on the way home today. All taken with the 85mm prime lens. Well and a camera too of course. ;-)
