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
or
- 62mm to 55mm thread converter
- 55mm to 37mm thread converter
- 37mm to 28mm thread converter
The second combination would, in fact be the better choice as it would minimize the additional distance that the connection is placed from the primary lens of the camera.
Note: Major stepping down is generally NOT recommended as it will result in serious vignetting.
