Nikon D5100: new lens back focusing problem

Tue, 24 Jan 2017 13:26:03 -0700

i never had this problem before. i had the 18-55mm kit lens, it focused fine. and then recently bought a new sigma 18-250mm lens, and suddenly i'm getting soft photos.

i lately realized it wasn't a lens quality problem, it was back focus.

when i'm shooting portraits for example, i keep a focus point on the eye, but what i'm getting in focus is an ear or something!!

this is persistent in every focus mode, and at all focal lengths.

i think its getting worse with time, it started with like 30% of the shots, now its like 90% is OUT OF FOCUS SHOTS! what do i do guys, help me.

Nikon D5100: Why is my camera taking black photos

Nikon D5100 is taking black photos. No, the lense cap is not on. Even in the live view it only shows black. Is the repair costly?

Nikon D5100: Date Time Keeps needing to be set

Thu, 20 Nov 2025 21:00:23 -0700

I understand there is a small Lithium Ion battery somewhere on the mother board but I cannot seem to locate it on any of the photo shown here. Apparently it is the CMOS battery, and it is very small. If I could be pointed to the correct board on any of these photos, maybe I could determine how difficult it is to replace. I also undersand it needs to have the 2 terminals desoldered on the old battery and then the new battery can be soldered in. This may be the correct Seiko battery part number
MS518SE-FL35E.

Nikon D5100: Problem with a 40 pin connector for the display

Mon, 29 Jan 2018 17:12:20 -0700

On reassembling the camera after repair, I have no display, every thing else is working fine.

I suspect the connector as I t doesn't seem to be sitting correctly, it said to disassemble lift the cable to disengage the connector.

Thirds is a type of connector that I am not familiar with.

My Nikon D 5100 will not power up, even with a full battery. The green light in the back of the camera will blink once when I insert the battery but nothing else works. Any help? Could it be the power board. If so how do I access the power board?

Nikon D5100: How do I realignment viewfinder

Sat, 15 Feb 2020 21:30:32 -0700

I have had a D5100 for several years. A couple years ago I dropped it. Everything still works except that I can not get a sharp image in viewfinder. It is impossible to focus manually but if I set up my focus points where I want, the autofocus will do a fine job. Images are perfect. Live view also works and gives sharp image but that drains batteries too fast. I have determined that the prism is slightly jarred out of alignment causing the eyepiece to be out of focus. Not sure how or if this is fixable. What is your experience with this area? Thanks.
