hi everyone,

I have a Tair3s and brought it to an air-training , however the position I took the picture was about 1,5km far from the airstrip and I can't get any closer. I had to add an 2xTC and the outcomes were (as you all know) softer than the softest , Does anybody here know how to improve the sharpness of the pictures ?? Thanks in advance.

Hello Mr. X :-)

I have had quite good results with the Tair3 and a Kenko Teleplus 2x MC7 or the Pentax Rear Converter 2x 6-lens-design.
That is to say, all the other M42 converters did not give me good pictures (they only have 4 lenses).
The best was the Kenko, stopped down to f5.6, which was a bit better than f8.
Shooting full open at f4.5 is not recommended.

Avoid shake by all means:
- real solid tripod, or bring some tent pegs or heavy things and tether the tripod to the ground. Beanbag on the wall / car roof /... would also work.
- 2s selftimer & mirror lock up or cable release (only when the tripod is very solid)

Avoid flare by all means:
- use a long lenshood
- shade the hood with your hand/other if needed

Avoid putting any filters on the lens, it will soften the picture any time.

Be sure to have the focus correct. You only really know when you can take a test series and control the focus on the camera screen with the 12x magnification.

Softer: Tair 300/4.5 + M42 MIR 2x on K100D

Sharper: Tair 300/4.5 + Kenko Teleplus 2x MC7 on K100D

I always had very few good pics out of a series of many shots.
Good luck!

edit:

I was curious and took your pic to the gimp and cooled down the colors and put some unsharp mask on it. I guess this is a heavy crop in the first place.

Hi Geogr,

Thanks for your tips. I will try it asap and send in the result

I did have the Kenko teleplus 2x 7MC but last time I was using the Quantaray MC7. I also use the original UV filter and rubber hood (equipped together with the fotosnaiper set). The camera was the *istDS, coz i have to save the K200D+ DA 55-300 for the flying ones, and I did set the aperture to 4.5 (big big mistake, I guess ). and my picture was only resized.

I also have some more questions for you
1. for the high noon of the tropical sun, which F stop you will recommend me ?
2. I have ordered 2 M42 Vivitar teleconverter, one 3x and one 2x, can the 3x provide good enough picture as it has more than 4 lenses and of course it will drag the image closer ?

again, thanks for you reply. It does help me alot

Hi Mr. tropical X :-)

As I said, my best f-stop with the Kenko was the 5.6. You could go to f8, if you still have enough shutter speed and need more depth of field (which I think you do not need here cause those airplanes are far away).

I am afraid not, my experience with such teleconverters is that you will loose as much as you gain.

I would do some test shots from your Tair+*istDS setup and then the same with your K200D+DA 55-300 combo. Then, postprocess to the same size and see which is better (there could be a surprise).

If you have a choice which days you are going, try to catch a day with clearer air. I know you're in the tropics, but maybe you can take some shots just after a serious thunderstorm or rain shower, or as early as possible. The better the air, the better the pics.

Apart from all that, you may have a look at the birder's threads, they know best :_)

Try to make the best of what you've got, that can be as much fun as shooting with the multi-$$$$ equipment.

Best, Georg (the other)

Anyone has experience with Zenitar-M 50mm 1.9? Is it any good? I'm considering it to be my first Russian lens

MC Zenitar K 85/1.4 (a K-mount 85/1.4 Russian Lens)

Here is (I guess) my only contribution to the Russian lenses "club", based on a Russian lens I had several years ago (which was the only Russian lens I've ever owned, and which I no longer have).

For a short period of time I had the pleasure of playing around with the unusual MC Zenitar K 85/1.4, an 85/1.4 K-mount Zenitar lens, unrelated to any of the other Russian 85's, as far as I know.

Below are some photos of the lens, followed by a few photos taken through the lens.

[I do apologize for the poor quality of the photos taken of the lens, which were made with the first Pentax digital camera (no, not the *ist-D, which was the first Pentax DSLR), the Pentax "EI-C90", featuring a 400 KP (yes, that's ~kilo~pixels) sensor - <g>.]

[OK, the images taken ~through~ the lens are not great, either, since they simply were scans taken from 4x6 prints.]

[Please remember that all of these images were created way back in the "digital pioneering days of yore", when bandwidth was pretty low, online storage space was pretty expensive, and digital hardware was pretty weak - <g>.]

"Abbott and Costello 85/1.4's" (next to an A* 85/1.4) -


"Hey, Abbott !!!" (next to an A* 85/1.4) -


The front of the lens with its lens cap still on -


Yes, this ~IS~ a K-mount lens -


No (obviously), this is ~NOT~ a Japanese Lens -


Proudly mounted on a Pentax LX -


With generous 72mm filter threads !!! -


It's "f/8 and Be There" (next to an A* 85/1.4) -


7 Elements in 6 Groups -


And, finally, here are a few sample images taken with the Zenitar K 85/1.4 (all at f/1.4) -





A ~most~ interesting lens ...

Fred,
nice lens, never seen one of them or heard of it. I like the old paper scans and your notes on them,
that has got a charm of its own! I still have two boxes full of 4x6 prints, shame shame.

Here's two more from today, K-mount MC Lomo Volna 1.8/50 on K100D

Rather heavy contrast applied here. Rainbow stripes is from lensflare.

Nice photos Ovim,
I like the quiet bokeh from the Jup. Looks like the snow has gone at your place also!

Here's some more bokeh test shots :-)

Thanks, it's still kind of gray/dirty everywhere, but I managed to find one flower with the Jupiter.
