digital camera

A successful inspection requires one with increasing miniaturization of the components overall microscopic image of the full circuit board, The use of a microscope with a narrowly limited eyepiece field of view is not helpful! For this reason, the EFA Picture Series developed!

Industrial versus professional

This series makes up the almost inexhaustible segment of the digital cameras Use and deliberately not only limited to industrial camera solutions! Because the steadily increasing presence of mobile phones with integrated digital cameras means that manufacturers of digital cameras from the professional and semi-professional sector are under increasing pressure.

Therefore, they are the real pioneers in the further development of this technology!

Resolutions of 24 million pixels per single image are no longer uncommon - they are standard! Lenses with highly coated lenses are currently experiencing a price offensive that recently seemed unthinkable! The combination of a high-performance sensor and an optimized lens at an attractive price makes the digital cameras from the professional and semi-professional area so interesting for the inspection of printed circuit boards!

The EFA Picture Touch series was therefore designed so that all common lenses with a minimum distance to the object of at most 45 cm can be used. This means that all relevant macro lenses are suitable for use in an EFA Picture Touch device!


Due to the strong competitive pressure on the part of the manufacturers of mobile phones, the acquisition costs for a professional digital camera are significantly more attractive than those for an industrial camera. But the real advantages come from the much larger market segment of professional digital cameras:

  1. Latest developments in sensor technology get the earliest possible entry into series production.
  2. The Number of providers of professional digital cameras is significantly larger than that of the providers of industrial cameras.
  3. The Selection of relevant lenses for an inspection in the microscopic area is not only clearly superior to that in the industrial area - in many cases it is only available there!
  4. In general, the area of application of professional cameras much more flexible to new shooting situations customizable by the user!


Digital cameras for the industrial sector are primarily designed to permanently deliver a defined image quality under industrial conditions. Therefore, these cameras are robustly built and optimized for your application!

Digital cameras from the professional sector are primarily designed as all-rounders and are not designed for maximum triggering. The number of times a digital SLR is triggered (DSLR) Camera has an average of approximately 150,000 releases and that of a digital mirrorless (DSLM) Camera at 200,000.

Assuming a professional digital camera would be used 5 days a week and 52 weeks a year, it could be used

200 shots

per day (approx.52,000 recordings / year) approx. 3 years (DSLR camera) or approx. 4 years (DSLM camera) do their job without failure.

400 shots

per day (approx.104,000 recordings / year) approx. 1.5 years (DSLR camera) or approx. 2 years (DSLM camera) work without problems.

On the cutting edge

Normally, however, technical development alone limits the useful life. Since this is measured in months rather than years due to the great competitive pressure, the next or the next generation is ready for use at the end of the service life of a professional digital camera.

This generation will then again have a larger sensor, a higher resolution or better focusing, etc. Reason enough to make an exchange. Certainly gladly before the end of life!

However, it is essential that the exchange into the next generation is often possible even without service in the EFA Picture Touch series.

Then and only then is the EFA Picture Touch user always up to date!
