means a step up ring is available from Photosolve. The smaller number (the "from" number) is the male side, and the larger ("to") number is the female side
means a step down ring is available. The larger number (the "from" number) is the male side, and the smaller ("to") number is the female side
means a thread converter is available. A flat thread converter provides the equivalent of a step down ring from a larger size thread to a smaller one, with no additional thickness or separation.
Where N/A is shown, it means that photosolve does not stock a single solution to the required size requirement (although it may be available from some other source). Very often you can combine various step down rings
, step up rings
, and thread converters
, to get the proper size.
For example: You need a 62mm to 28mm step down
You can accomplish this by using the following three items:
- 62mm to 49mm step down ring
- 49mm to 37mm thread converter
- 37mm to 28mm thread converter
It is important to minimize the "thickness" by using thread converters as often as possible as they do not have the thickness of a standard step down ring.
Note: Major stepping down is generally NOT recommended as it will result in serious vignetting.
