Sticky: Adapted lenses tested on the Q : the reference thread

We've had some nice spring weather recently and yesterday afternoon I went out to get a moonshot with the Q10 and the 80's oldie Canon New FD 500mm f/4.5 L. The birds were chirping in the trees nearby and a few stayed put for just long enough so I could get a few shots of them as well! I'm not a very good birder, but would guess it's a European Greenfinch and a Fieldfare (Thrush).

Shots wide-open at f/4.5. The bird images were taken some distance away and are heavy crops. The moon was of course also far away but is uncropped as it just barely fits into the image at 500mm :)

EDIT: Added a blackbird shot at f/5.6 as well. It kept singing, seemingly unbothered by my presence, so I was able to get the focus just right.

Lens notes:
- Impressive sharpness at f/4.5 - the images turned out quite nice IMHO regardless of the demanding small sensor
- Impressive control of CA - a tiny amount was present but could be mostly mitigated in the raw editor
- Not easy to nail focus due to 1) shallow depth of field wide-open, and 2) EVF shake when touching the lens. Sturdy support + an IR remote + a red dot sight for finding the subject is recommended!
- Colors are a bit flat - dial up vibrance and contrast!

All in all - it's not a particularly easy lens to use at 2810mm eq. focal length, but I think it can work well e.g. for photographing (still) wildlife in good light if the subjects are far away and you can't get closer.

Thanks barondla and kwb!

With this one it's indeed the case of lens holding the camera. Most definitely to be used on a good tripod with the Q, and a gimbal also helps a lot.

I have adapted the nFD 500mm f/4.5 L on other mirrorless cameras with great results, but have to say I was pleasantly surprised by the output of this combo. The Q really pushes legacy lenses with regards to sharpness and detail - many old lenses' sweet spot is around f/8, which is well into diffraction territory on the Q. This is not the case with this lens. It's sharp wide open and with good enough control of purple fringing that it can produce great results on the Q - if you are willing to work with the weight and size, price, extremely long equivalent focal length, and also face the reality of atmospheric effects.

Makes one curious about trying a good 300mm f/2.8 :D it would enable photography in lower light. Ah well...

Long reach Q shooters - what type of head (+support) do you use?

Thanks barondla.

The RH1 gimbal is a simple but nice piece of engineering without bells and whistles, very happy with it. Maybe it's the perspective in the picture, but it actually does have some size to it. Even a FF camera with a battery grip would work with this lens without restricting vertical movement that much. Lensmaster also has the "T1 Traveller" sidemount gimbal if you really need to save weight - but from the pictures it seemed to me that that one would restrict movement, so I went for this one.

Best regards,
Markus

Awesome setup, Phenix!

For reference, I thought I'd post an update of what I ended up purchasing for anyone stumbling upon this thread. I have attached an image that shows the equipment I have used with the Q for long range shooting. My equipment choices apply to Europe.

1) The gimbal head is the side-mount Lensmaster RH1. I have found it sturdy, easy to use, and not that heavy.
2) Based on suggestions from the forum members above I purchased a cheap red dot sight and an adapter. I was skeptical at first, but indeed, it does help a lot with finding the subject, especially when using the Q with a 300mm lens. The RDS was a "Pinty Tactical Red & Green Dot Sight 1x40mm Reflex Riflescope" which can be found on Amazon. After it has been calibrated, it is very easy too look through it and acquire the subject, given the 1:1 reproduction ratio.
3) In order to attach the RDS to the camera, I ended up with buying an "Adapter for reflex sights to the hot shoe of DSLR cameras" from teleskop-express.de. It's quite expensive for what it is, but it fit the RDS and gets the job done.
4) I think you also need a remote control. You will get shake whenever you touch the camera at long equivalent focal lengths, unless you have a super-steady tripod. Of course, you can use the self-timer, but I found that working with a remote is a lot easier.

The tripod is a light Benro travel tripod which is not very sturdy - I have yet to pull the trigger on a more rigid replacement, as I think that the use of a remote helps a lot.

Thanks to everyone for their input - I'm looking forward to shooting long-range wildlife later this year at the equiv. focal length of 1680mm!
Best regards,
Markus

Dear kwb,

Thanks for the tip about the poor man's gimbal and the illustrating image! I distantly remember seeing this somewhere, but I had forgotten about it. Have to admit though that I'm heavily eyeing the side-mount gimbal right now :) Thanks also for the links to the Celestron finder and mount adapter, will check those out!

Woah, nice gallery! :cool: Great wildlife shots! Really liked the picture of the Orion Nebula too!

Best regards,
Markus
