Website structure

Our website is a catalog of photographic systems. A system is a collection of cameras, interchangeable lenses, flashes and other accessories designed for them. Each system, camera or lens has its own page on our website.

For example:

  • Canon EOS - A popular 35mm full frame SLR system consisting of Canon EOS series SLR cameras (both film and digital), Canon EF series lenses, Speedlight flashguns, adapters and other products [Please note that there are also Sigma, Tamron, Tokina etc. lenses designed for the Canon EF mount, but these are third-party lenses that cannot be considered part of the Canon EOS system. We do not display such lenses on the system pages, but of course they are recorded in our database].
  • Canon EOS 650 - Canon’s first EOS camera.
  • Canon EF 50mm F/1L USM - One of the first lenses for the Canon EOS system. World’s fastest autofocus standard prime lens for 35mm full-frame SLR cameras.
  • Tamron SP 45mm F/1.8 Di [VC] USD F013 - One of the best fast standard lenses designed for 35mm full-frame SLR cameras, including but not limited to Canon EOS cameras.

There are currently 93 autofocus and popular manual focus systems in the database, so you have plenty to choose from. Please do not perceive our website as specializing only in vintage manual focus lenses - we pay equal attention to both vintage and modern photographic systems.

The item "LENSES" of the website's main menu contains various options related to the choice of system:

  • in the section "Timeline", the systems are sorted by manufacturer and date of introduction to the market;
  • in the section "Systems", the systems are sorted alphabetically;
  • the section "Collections" contains thematic lists of lenses based on some feature (for example, ultra-fast lenses, pancake lenses, etc.);
  • the section "Genres" allows you to find suitable lenses for your camera by a particular genre of photography;
  • finally, the section "Advanced search" provides more possibilities for finding lenses. In particular, it allows you to find third-party lenses designed for your camera, and/or display only lenses of a certain type (for example, macro lenses).

Just like any other website, we have a search bar. However, the search is carried out only among lenses and only by their names, focal length and speed. Don't try to search for any phrases from lens descriptions - nothing will be found.

Advantages and disadvantages of our website

Like any website, lens-db.com has a number of advantages and disadvantages. We tried to honestly list the main ones:

ADVANTAGES:

  • the database is based strictly on official data from camera and lens manufacturers. Therefore, in the field of photographic equipment, our website is the world's most reliable - and this is not an exaggeration or a desire to stand out, but a fact;
  • we do not post unverified information (especially rumors), advertising, politically-motivated content or other informational garbage;
  • we do not have advertising contracts with any of the manufacturers of photographic equipment, so we provide objective and impartial information;
  • our website provides unique features that you will not find on other websites that you consider similar: automatic comparison of specifications of autofocus lenses, automatic search for suitable lenses by camera and genre of photography, and much more.

DISADVANTAGES:

  • no reviews and lens tests (but it was meant to be);
  • it is not possible to upload sample images (sorry but we won't change that);
  • no little-known lenses or Chinese lenses (to be honest, we do not consider this a disadvantage, but still added to the list).

Lens names

On our website, lens names are recorded in the database as they appear on the lens barrel. The only exception we make is for focal length (range) and speed. In whatever form they appear on the lens barrel, we always bring them to the following format: XXmm F/x.x, where "XX" is the focal length in mm, and "x.x" is the speed. For example, 50mm F/1.4 or 18-55mm F/3.5-5.6. Wherein we always omit trailing zeros after the decimal point. For example, Canon Lens EF 50mm 1:1.0 L Ultrasonic is recorded in our database as Canon EF 50mm F/1L USM (also note that there is no space between 1 and L).

For autofocus lenses, we do not include the anti-reflective coating marking in the name. For example, Fujinon lens Super EBC XF 90mm 1:2 R LM WR is recorded as Fujifilm Fujinon XF 90mm F/2 R LM WR in our database. The only exception we make is for Pentax autofocus lenses: the smc or HD marking is always present in their names, because it has developed historically. For example: smc Pentax-D FA 100mm F/2.8 Macro WR, HD Pentax-FA 31mm F/1.8 Limited.

We also reserve the right to exclude words that have no significant meaning when recording lenses in the database. For example, Sigma High-Speed Wide 28mm 1:1.8 Multi-Coated Aspherical is recorded as Sigma 28mm F/1.8 Aspherical ZEN in our database: the words "High-Speed" ​​and "Wide" are excluded as redundant, the words "Multi-Coated" are excluded, since all autofocus lenses are multi-coated, and the acronym "ZEN" is included because it was used with this lens in Sigma catalogs.

Lens lists

As you visit the website, you will have to deal with lists of lenses. Here is a short description of them.

Model history

In the "Model history" list, lenses are displayed in chronological order: the lower a lens is in the list, the later it was released. The lens you are at is highlighted in blue. Special limited editions are indented. A change in the background hue indicates a change in the optical design. For example:

Nikon AF NIKKOR 50mm F/1.8DA6 - 50.45m⌀52 2002 
Nikon AF-S NIKKOR 50mm F/1.8GA7 - 60.45m⌀58 2011 
Nikon AF-S NIKKOR 50mm F/1.8G Special EditionA7 - 60.45m⌀58 2013 
Nikon AF-S NIKKOR 50mm F/1.8G Special Gold Edition (1000 units) 2014 

Immediately after the column with the lens name, there is a column that indicates the type of diaphragm, then the optical formula (number of elements - number of groups), the closest focusing distance in meters, the type and size of filters, and, finally, the year when the lens was announced.

Diaphragm types:

Built-inBuilt-in--Not available

Alternatives among lenses that are part of a system

Lenses in this list are always sorted by focal length and speed. A comparison feature is available for autofocus lenses: click on the "Compare" link and the website will display a list of advantages and disadvantages of a lens compared to the lens you are at. The comparison is done automatically and based on the lens specification. Next to "Compare" are columns with the number of advantages (green) and disadvantages (red).

Alternatives among third-party lenses

This list contains lenses that do not belong to any system, so they are always sorted by manufacturer name. As in the previous list, a comparison feature is available for autofocus lenses.

Miscellaneous conventions in lists

The "Pro" mark indicates that the lens is a professional model.
