Frequently Asked Questions - H. Lehmann's Help Guide to Diagnose a Fault with your Digital Camera, DSLR lens & Speedlites

What is firmware for my camera?
Firmware is the software that manufacturers install within your camera to operate the electronic functions of your camera.

Does my camera need a firmware update?
Manufacturers will periodically update the software that runs your camera as part of their continuous product improvement. When your camera comes BOOKED IN to our workshops at H. Lehmann for a routine service we will if required install the very latest manufacturers firmware.

I am getting distorted pictures and very strong tints and colour casts.
Strong colour casts, distorted images and lines running across your images can be a sign that there is a problem with the sensor in your camera. H. Lehmann are a Nikon authorised service centre. We also service and repair Canon Film Cameras and DSLR cameras together with Sony, Panasonic, Sigma and other makes. Talk to our service reception or arrange to send your camera for assessment. There is more information on camera repairs on the Camera Repair pages.

My camera has had high usage, can the shutter be replaced?
Yes the shutter mechanism can be replaced on most digital slr cameras, we have stock of Canon and Nikon replacement parts and can facilitate a replacement quickly. We recommend that the mirror box is replaced at the same time as the shutter.

Can you supply a shutter count record for my camera?
Canon do not provide software that enables the shutter count to be measured. There are third party software but we are unable to comment on the accuracy or provide a reading.

Why is lens calibration important?
A lens is an incredibly sophisticated series of optics aligned in a very specific manner, a knock, a bump or through normal usage the optics can shift and therefore need recalibrating to provide you with the sharpest image. 

I can see some fungus in my lens?
Fungus can appear on a lens when a lens has been stored after being subject to damp or wet conditions. Avoid rapid change of temperature when returning your lens into your kit bag after use in cold or damp conditions as this will lead to condensation and hence the formation of fungus.

Fungus will quickly damage the optics inside your lens; your lens should be booked in for service as soon as possible and may require replacement optics.
