1. Line up the index mark on the back of the 3D Lens in a Cap 9005 with the index mark on the camera body and attach it to the camera.
2. This lens is for use with sub-
frame Single Lens Reex
3. This is a manual lens. There are no electronics. Turn off auto-focusing before using the lens. Aperture priority auto­exposure should work. If not, turn that off as well.
4. Usage: First select aperture using the aperture slider. Three click stop apertures (f11/f16/ f22) are provided. Set focus
from 1.5 m (5 ft.) to innity.
5. The 3D Lens in a Cap 9005
works with TTL ash, Aperture
Priority (AV) or Program (P) mode exposure on many cam­eras. For manual control use a light meter or exposure chart.
6. The 3D Lens in a Cap 9005 has no auto diaphragm, so
the viewnder image darkens
when f/22 is chosen. This al­lows the user to judge depth
of eld, and has no adverse effect on the nal picture.
7. This depth of eld scale gives
an estimated distance range in which all objects will be sharp for a given aperture.

D - Distance A - Aperture
If the lens is set to f/11 and
focused at 5m, depth of eld
will be 2.8m to innity, which is
the optimal pan-focus con-
guration for 9005 style 3D
photography.
8. Depth of eld is very useful
for stereo photography. High image sensor sensitivity com­pensates for small aperture. ISO 200-400 will give excellent results. Loreo 3D lenses in the right hands can take beautiful 3D photographs. Maximize the potential of your Loreo 3D lens by using a monopod and a high quality modern DSLR.
9. Make sure the lens is aligned with the camera on the hori­zontal. This can affect the ver­tical alignment of the 3D image pair.
10. The two 58 mm threads on the front can be used for mounting
lightweight lters, lens hoods,
wide angle lenses and tele lenses. Attachments should be selected and used with care so
as not to damage the thread. Converter lenses should be matched at purchase.
11. In selecting accessories for the lens make sure that the maxi­mum outer diameter does not exceed 85 mm. The minimum inner diameter should not be less than 44mm for 4:3 format 9005 lenses.
For APS-C format, there are
very few tele converters with
a sufcient inner diameter to
avoid vignetting. Photos taken with tele converters on APS-C format 9005 lenses will most likely need to be cropped after­wards.
Since the wide stereo base
of the 9005 is suitable for 3D photography at mid-distance (5m or more away), users can multiply the tele effect simply by cropping the image pair. Tele converters can make it more convenient, but are not essential.

12. For 3D photographers, bal­ance between left and and right frame sizes is very im­portant. With Loreo 3D lenses, the perceived position of the center line can sometimes be misleading.
With an SLR camera, the pres-
ence of mirrors prevents the partition between the image pair being extended all the way
to the lm plane. As a result,
the center line can never be
clearly dened. There will
always be some overlap. Even with mirrorless DSLR cameras, in which the partition can be
set much closer to the lm
plane, there is still a gap.
For this reason, the 9005 3D
lens has been set up to pro­duce images with an overlap as opposed to a thick dark band down the middle. The fol­lowing two images were taken with the same 3D Lens in a Cap 9005 on the same DSLR camera.
In the rst image (above), the
right hand frame seems to en­croach upon the center line. In the second image, the two sides appear to be well balanced. Sub­ject matter and lighting make all the difference.
13. Internal reection will occa­sionally cause are, which is visible in the viewnder. Some-
times a ghost image will ap­pear. This can be avoided by shifting the angle of the lens, or shielding the side to avoid light shining directly in. Hoods can also be added using the
lter mounts in the front.

14. 3D images taken with this lens are best viewed with Loreo 3D print and screen viewers. Some people can freeview 3D images. The image pairs have a high degree of cor­respondence, so feel free to experiment with viewing meth­ods which require symmetry (anaglyphs).
15. Image pairs are not pitch-
adjusted for cropping as in lm printing days. Some may nd
fusing 4R prints on a Deluxe
3D Viewer difcult. If so, use
3R prints. Viewing with the Lite and Pixi Viewers should not be a problem.
16. Different people have differ­ent eyesight, so you may have to move the viewer closer or further away from your eyes for the stereo effect to appear.
17. Tips for taking dramatic 3D pictures: As in conventional photography, the subject will usually be placed in the center of the picture composition, and exposure is best if the light source is behind the photogra­pher.
18. When taking pictures you can point your camera slightly up or down, but always keep it horizontal. Never hold your camera vertical, since you would not be able to view the pictures in 3D.
19. Avoid the subject being too close to the lens (<1.5 m). This leads to discomfort in viewing. Avoid there being too much empty space between foreground and background if closeup shots are taken of a subject at 1.5m, the back­ground should not be more than 3 meters away.
The subject in this picture is the parrot. It is too close to the lens, so parallax compensation no longer works. Note how the par­rot does not appear in the same relative position in each frame.

20. A 3D camera or lens records both the shape of things and the depth of the scene. 3D pictures should show fore­ground objects as well as the background scene. When pho­tographing a person, include objects in front, and an inter­esting view behind.
21. Compose the picture with the subject material away from the edges. This will improve cor­respondence between the two images.
23. Viewing: Put a 3D picture in the Deluxe 3D Viewer (bottom left) and hold the eyepiece 6 inches from your eyes. It may take a few seconds for your eyes to adjust to the 3D image.

24. Sharing: One of the great joys of 3D photography is in sharing images with friends and family. Foldable, mailable viewers such as the Lite 3D Viewer (print viewing) and Pixi 3D Viewer (screen viewing) are ideal for this purpose.
25. For best clarity when viewing 3D pictures avoid bright lights
reecting on the viewing lens
surface. Natural light falling on the stereo print and not on the viewing lens, will always give the best stereo effect.

22. Printing: The 3D Lens in a Cap 9005 takes two side by side pictures in each frame. The 3D effect is viewable immediately after processing. 3R and 4R prints work best. Make normal prints. Do not make half frame photographs.
The rst picture on the right
would look better if the lens were further back, and the young lady and the cool cat were away from the edges of both picture frames.
Most people compose an image in a single frame of the image pair. When doing this, take note of what is happening on the other side to make sure the sub­ject is not cropped at the edge.

Care and Troubleshooting
1. Slight rain or salt water splashes on the lens body should be harmless. Wipe with a clean cloth. A soiled lens may be gently cleaned with lens tissue
moistened with lens cleaning uid.
Never put liquid lens cleaner directly onto any lens. Do not wipe with dry tis­sue as it may scratch the lens surface.
2. Nikon digital SLR cameras may need to be switched to manual mode before they will function with a non-Nikon lens. Minolta and Sony SLR cameras need to have the shutter lock disabled. Some Sony models have to function in manual mode.
3. The 3D Lens in a Cap 9005 is a lens with an unconventional shape. With two lens converters attached, it will be front heavy as well. Lightweight ac­cessories are strongly recommended. For example, wide angle converters can range from 160g to 250g apiece. Users should take care not to drop the lens or bump it against anything while it is attached to the camera. The shock load can cause damage to the SLR camera body and to the lens mount of the 3D lens.
4. The 3D Lens in a Cap 9005 should be detached from the camera when not in use.
Digital SLR Compatibility (as of April 2012)
1. Canon EOS D30, D60, 10D-60D, 300D­600D, 1000D, 1100D, 7D (EOS mount) ­Most Canon SLR cameras work with the Loreo 3D lenses in auto-metering mode, but exposure bias should be set to -1.5
or -2. The 300D has ash exposure bias
disabled, but it is known that people have found ways to re-enable it.
2. Nikon D1, D1X, D1H, D2H, D2X, D100, D200, D300, D2H, D40-D90, D3000­D7000 (Nikon mount) - Nikon digital SLRs work with Loreo 3D lenses in manual mode. In most Nikon digital SLRs, over-exposure is shown on the LCD screen after a picture has been taken. This function can be used in place of auto-metering.
3. Pentax *ist D, *ist DS, DS2, DL, DL2, K-x, K2000, K-7, K-m are compatible. The K100D, K110D and K200D cannot
be tted with a 9005 due to the large ash housing. The K10D and K20D are a tight t. Most Pentax SLR cameras work
with Loreo Lens in a Cap products in auto-metering mode.
4. Fuji Finepix S1 Pro, S2 Pro, S3 Pro, S5 Pro (Nikon mount)- Fuji digital SLRs work with the Nikon mount Loreo 3D lenses in manual mode.
5. Minolta Maxxum 5D, 7D (Minolta AF mount) - require shutter lock to be disabled. Minolta digital SLRs work with Loreo 3D lenses in automatic metering
Parallax Compensation
1. The 3D Lens in a Cap 9005 has a focus coupled Paral­lax Compensation system. When the lens is focused on a subject at a given distance, the point of convergence is automatically adjusted within the unit itself to suit the object distance.
This works from 1.5m to
innity. The adjustment of the
relative positions of the im­age pair can be viewed in the
viewnder, or with Live View in
modern digital SLR cameras.
2. Once a user learns how to use the lens, focusing can be done by parallax compensa­tion alone. When the subject appears in the same relative position in both the left and
right image in the viewnder, it
will automatically be in focus.
The distance from the New Year Tiger’s snout to the edge of each frame is the same. The lens is now focused on the New Year Tiger at
2.2m
Note the discrepancy in the distance from the grey tree trunk in the background to the edge of each frame.
Note the distance from the New Year Tiger’s snout to the center line. The discrepancy between the two images in the pair indicates that the lens is not focused on the New Year Tiger.
The distance from the grey tree trunk in the background to the edge of each frame is the same. The lens is now
focused at innity.
mode. When set to “P”, the exposure compensation needs to be set to -1.5 stops. When set to “A” (aperture control), exposure compensation does not need to change. The anti-shake feature improves lighting conditions by 1-2 stops.
6. The Sony Alpha Lens mount is compat­ible with Minolta AF lenses. The Sony Alpha DSLR-A100 and A700 (Sony/ Minolta AF mount) require the shutter lock to be disabled. Loreo subframe 3D Lenses are known to work with these cameras. The Alpha A100 and A700 work with Loreo lenses in automatic mode. The anti-shake feature improves lighting conditions by 1-2 stops.
The A200, A230, A300, A330, A350,
A500, A550, A850, A900 (Sony/Mi­nolta AF mount) do not have a separate feature to disable the shutter lock. The camera has to be put into manual focus mode (MF).
Note: The A850 and A900 are full frame
DSLR cameras.
7. Sony NEX 3, 5, 7 are compatible with all Loreo lenses, using an E-mount adapter. For example, a Sony E-mount to EOS adapter can be used to attach an EOS mount 3D Lens in a Cap 9005A to an NEX. Third party mounts may have slight rotational mis-alignment. “Release w/o lens” must be enabled for the camera to work without a Sony / Minolta AF lens. This is similar to disabling the shutter lock feature on Alpha series DSLRs. Aperture priority auto exposure works. Manual exposure works with live view.
