That trick dosent work on my canon 50d and mp-e 65 I have already tried it before but I will try it on my other canon lenses and see if it works on them.
It's usually stated as if you just select the aperture and remove the lens, which I don't think works on any EF lens. (Not on any I've tried anyway.) You need to remove it while the aperture is actually stopped down. Either using DOF preview, or if your camera doesn't have that, during exposure.

Anyone tried any of the Jupter 12 lens - m39 mount?
I'm curious to know if the rear element will clear and if it can be installed safely... I'm still waiting for the mount so didn't had a chance to try it - and I am dying to know if it works.

Thanks!

Carl Zeiss Jena Sonnar 135mm f/4

Hi all,
new here and not sure if I should be here or on the "reach of the Q" thread. Anyway, it seems no one has posted on this lens yet which IMHO turns out to be a real gem.

Image 1 was taken from about a kilometer away and neatly illustrates the quality of the lens and the problems of the rolling shutter
Image 2 was shot from about 500m away. Both on a tripod, while image 3 was shot handheld.
Cheers
Chris

Samyang 500mm f/8

for some serious reach and IMHO impeccable optical performance. Bought mine used for eur 30,- on *bay, it is labeled Walimex, probably also available as Vivitar, Bower etc. German readers will recognize this as the modern incarnation of the Wundertüte that was sold 30 - 40 years ago under the Beroflex label.

Distance about 1km, stopped down to f/11.

Transit, it depends on what range you are trying to shoot in and choice of subject. For extreme photography, the Pentax DA*300 is hard to beat. For less money the Pentax DA 55-300 is a knock out. It is even hand holdable for some.

Many, like older, 135mm lenses in the f2.8-3.5 range. The Pentax 135 f3.5 is small and inexpensive used. Others use 90-100 macro lenses ( all seem good ). These give a nice "500mm" range.

A 50mm lens is a very small, and bright short telephoto. This does enter the range of Q specific lenses. The 06 zooms to 45mm with AF.

Q users also adapt C mount or Pentax 110 lenses. These lenses can be normal or even wideangle. The Fujian 35mm is very inexpensive for a new C mount lens.

Get some adapters and hook your Q up.
thanks

My most used adapted long lens for birding is the DA*300, the image quality is fantastic.
That is why I adapt most often.
For macro the DFA 100 WR is my most used lens.

Computar 8mm / f:1.3 (Model M8513-old version) C-Mount

Bought this lens from eBay for $22. Mine's the older metal-bodied version with f-stop & focus distance markings. The new plastic-bodied version with no f-stop or focus scale markings, but optically identical, is here. It's also available new from B&H for $70, here.

Here is what it looks like on the Q:



All of the following were shot JPG with the original Q. Only post-processing was a contrast bump in Photoshop. In the interest of keeping the page bandwidth down, I'm hotlinking instead of posting the images directly. Since I don't feel you can get an accurate idea what a lens does when looking at a reduced image size, all linked images below are original 12.4 MP size.

==============================================================================

These pics show the amount of halo distortion around white text on a black background at various apertures: (Taken on a copy stand.)

Wide open at f:1.3, there's A LOT of halo.

At f:2, it's useable.

At f:2.8, it's better yet

At f:4 it's virtually gone

Here it is at f:5.6

==============================================================================

These pics show general sharpness: (Taken on copy stand. - Note: The girl's face is out of focus on the original photo that was copied. Not a fault of this lens.)

Wide open at f:1.3

At f:2

At f:2.8

At f:4

At f:5.6

==============================================================================

The following shows out of focus highlights: (It as 4 aperture blades, so a bokeh monster it is not.)

Wide open at f:1.3

At f:2

==============================================================================

Specs:

8mm focal length equivalent to 45mm "normal" lens on the Q.
4 aperture blades
Stepless aperture adjustment
2/3" sensor coverage
35.5mm (I think) filter threads on mine (no filter threads on newer version)
Focus distance & aperture markings. (not on the newer version)

PROS:

Useful and fun lens
Cheap
Reasonably sharp at f:2, and even better at 2.8 and slower
Excellent build quality
Smooth operation
Focuses easily with focus assist on the Q
Very little vignetting
Virtually no fringing
Tiny size is ideal on the Q
Truckloads of halo wide open might be useful for a dreamy LOMO effect.

CONS:

Manual focus
Soft edges
Bokeh isn't great
Truckloads of halo wide open not useful for anything except a dreamy LOMO effect. (It's a double-edged sword kinda deal.)

For under $30, I think it's a keeper.

Here's a couple quick test snaps taken in daylight around f:2.8 to f:4 with it:

The 90mm and 180mm Voigtlaender Apo-Lanthars.

If you lay off the coffee,
you can freely use the 90mm hand-held,
and the 180mm can be hand-held if you get some support.
