You have the classic signs of the most common binocular fault: a bent or broken eyepiece carrier yoke.

The cause is usually due to the binos being dropped or stored standing on the eyepieces. The only cure is a replacement yoke, but the repair is rarely cost-effective unless the binos are really expensive and top-quality models. Yours probably do fall into that range, so contact an optical repair specialist for an estimate.

Broken/bent yokes cannot be repaired: If bent, then it's near-impossible to unbend them accurately enough and in any case the process will always either break the yoke or will severely weaken it. Broken yokes cannot be glued together as the contact point is just too tiny for the loads it carries, and as it usually bends before breaking you'd simply end up with a bent yoke afterwards even if you could glue them.

That's the backfocus problem. Take your camera to a Sony service.
If the lenses are ok, they will do an adjustment. If the lenses are defective, they will
replace the lenses, but that costs much.

Can you use the twist-barrell zoom lens on a Sony DSLR camera (or any DSLR) when the camera is set to auto-focus? I've been told that this damages the gears in the lens if you do. Thanks for your help.


You can zoom completely independent of the focus.

Some lenses immediately override the autofocus when it senses you turning the manual focus ring. Other lenses don't, and you can damage the lens by forcing it. It depends on the lens, so you'll have to consult the documentation for the specific lens.

Put the diagonal into the rear focuser-- then put the eyepiece into the diagonal. DO NOT use the 2 x barlow if you have one. AND the 4mm may also be too much magnification for this size telescope.

So-- put the eyepiece with the largest number written on it into the diagonal and practice focusing on a distant object during the daytime. DO NOT POINT the scope at the sun! You will be instantly blinded!

Using auto focus 35-55 mm lens on d40x will not take picture but if I use manual focus, I can take picture.


It is because the lense is only an AF lense. The d40x doesn't have an on-body auto focus motor so that needs to be on the lense. I have a d60 and have the same problems. You can use the manual focus on the AF lenses; however, to use auto focus, you need to buy an AF-S lense. It's disappointing I know, but that's the price we must pay for saving on our body lol
