CARSON HookUpz 2.0 Smartphone Optic Adapter User Guide

Smartphone Optic AdapterCongratulations on selecting your new HookUpz Smartphone Optic Adapter! In order to achieve optimum performance, please follow instructions for proper use and care.














Press optic clamp arms together to open adapter and remove from optic. To minimize an audible click noise, or if the optic lock doenot release automatically, rotate it upwards tounlock.


To save your alignment, make no further adjustments to the top clamp and alignment knob. Simply remove phone using right clamonly as shown in Fig. 4.


The alignment of your phone to the adapter should be saved from the initial setup, so many steps can be skipped (Fig. 1-2, 7-10) and only a quick fine adjustment of the alignment may be needed.



Q1: I am trying to enlarge the image on my phone but its still a small circle, what can I do?

A1: To maximize your image, select video mode and/or pinch your phone screen to digitally zoom. Depending on the combination of your phone and optic, you may need to use the included lens spacer. Insert and snap lens spacer into place as shown in figure below, and then reattach to optic. If image size does not increase, remove lens spacer or that phone and optic combination.

Q2: The top clamp touches the round corner of my phone not the top flat edge of my phone. What do I do?

A2: This is normal for some models of phones. Just push as flush to rounded edge as possible and lock top clamp as normal.

Q3: I can’t align my phone vertically with the top clamp. It won’t fit. What should I do?

A3: If you go through the alignment process (Fig.7-11), and there is no way to achieve vertical alignment because it’s restricted by the top clamp, try removing your phone case. Alternatively, you can remove top clamp assembly using screw as shown in Fig. 21. For this configuration, you will not be able to save your vertical alignment between uses.Your phone will have to be adjusted for vertical positioning each time it’s placed within the adapter. We recommend you save these four parts for use with other phones, and you can reassemble the top clamp as shown as in Fig. 22.

Q4: Can I use this on my riflescope?

A4: No, it is not recommended because of the long spacing required between the eyepiece of a riflescope and your eye so that the image is very small on your phone screen. Also, we do not suggest using a firearm with the adapter on a riflescope, due to recoil.

Q5: My image is not centered or is not a complete round image, what is wrong?

A5: Adjust phone alignment in vertical direction using top clamp (Fig. 10), and in horizontal direction by using alignment screw (Fig. 8). Check that phone is flat on adapter (Fig. 6), and adapter is fllush with optic (Fig. 17).

Q6: My phone rotates on the eyepiece when used in landscape (horizontal) mode. What should I do?

A6: If the eyepiece can rotate on your optic, then you can try the following:

  1. If your eyepiece can rotate outward, then you must place adapter in orientation to counter the rotation.
  2. If the eyepiece has any method to secure from rotation such as a screw set, use it to lock down the eyepiece.
  3. If above solutions are not possible or do not work for your application, it may not be possible to use in this mode. Please use only in portrait (vertical mode).

Q7: Why am I getting reflections and/or glare in my image?A7: If there are bright spots in the image itself, this may occur with indor lighting. Please avoid overhead lighting or change the angle of the lighting relative to the phone. Also, please use without flash to avoid reflections and/or glare in photos. If there’s glare on your phone screen that makes image hard to view, increase brightness setting on phone and view from a position with less overhead light.

Q8: My other phone camera or flash is covered by the adapter. Why is that?A8: First, we recommend using the device with only the primary rear camera. If problems perist, please contact customer support. Second, the flash can be covered, and is not needed for use with optic. We recommend flash setting is turned off at all times when using adapter.

Q9: I have a large eyepiece, but it seems like it won’t fit or it’s too tight to get one, what do I do?A9: For eyepieces at the maximum range (58-62mm), the adapter must be opened to its maximum, and then some pressure must be used to push the adapter over the eyepiece. Any eyepiece beyond 62mm in external diameter should not be used with this adapter. For these largest eyepieces, do not use the optic lock. Also, it’s important not to leave the adapter attached to these largest eyepieces for longer than two continuous hours, as it could cause permanent wear to the springs.

Q10: The adapter is sagging on the eyepiece and not staying flush, what do I do?

A10: Make sure once the adapter is flush on the optic, to use the optic lock as shown in Fig. 18.

Q11: Does this work on a tripod?A11: The adapter itself does not have a tripod mount. However, for best stabilized images and videos, we suggest the optic used is mounted to a tripod.




  • Tap object of interest on your phone screen to autofocus.
  • For videos, tap and hold object of interest on phone screen for a second to lock focus. Tap again to release the focus lock.
  • In low light conditions, turn your phone screen brightness to its lowest level. The rubber parts glow in the dark making it easier to use the adapter.
  • For long sessions, try using battery cases or phone chargers to prevent your battery from draining.



  • Share photos and videos through various apps (e.g. Face Time, Messages, Facebook, Instagram, etc.)
  • Apps that allow you to sex exposure and focus manually can expand the potential of the adapter. This is especially helpful for telescopes to set longer exposure times to get the best images of sky objects.



  • To prevent shaking:                                                                                                           1.Use your headphones. Volume butter will now act as shutter button.                               2.Attach to tripod.
  • Many phones have image stabilization features. Check your phone and turn on this feature if available. If not, there are camera aps with stabilization features.



  • Adapter should be cleaned with a soft, damp microfiber cloth only. Do not use any chemicals, abrasives, or solvents.
  • To avoid damage, always store adapter in protective case when not in use.
  • Do not leave item attached to optical device as this may weaken the springs over time.
  • Store in dry area at room temperature.
