Canon PowerShot A610/A620/A630/A640

Sigma DP1

Introducing the Lensmate Powershot A610/620/630/640 52mm and 58mm lens adapters. Like all our lens adapters, the A610/620/630/640 adapter is machined from 6061 aluminum. It's then bead-blasted and anodized silver or black to complement the finishes of the two cameras. Since the A610 is primarily silver and the A620 is a pewter color, we're offering two color options. Other than color, the silver and black adapters are identical and both have an anti-reflective coating on the inside.

In addition to allowing the use of filters and conversion lenses, the adapter protects the delicate zoom mechanism and lens from the inevitable bonks of everyday usage, as well as allowing the camera to be left on with a lens cap in place. It also allows the use of a conventional clip-in lens cap, which stays in place until removed. Having a metal thread, it will never strip or cross thread like a plastic adapter can.

Although the A610/620/630/640 has the same 35mm - 140mm focal range and uses the same Canon conversion lenses as the G3/5/6, it's an entirely new lens design. There are several non-Canon wide and teleconverters that are compatible with the new cameras and you can click on the images below to see our test samples.

Canon PowerShot A610/A620/A630/A640 FAQ

1. What's the length of the Lensmate A610/620/630/640 52mm adapter?
1.900" or 48.25mm.

2. What's the length of the Lensmate A610/620/630/640 58mm adapter?
1.820" or 46.22mm. This is exactly the same length as the Canon LA-DC58F 58mm adapter.

3. Why is the 52mm adapter longer?
The Canon 58mm adapter is designed to be compatible with their converters only. We designed our 52mm adapter to provide the necessary clearance for the most popular converters, yet as short as possible to minimize the potential for vignetting.

4. Can the 52mm adapter itself cause vignetting at the wide angle setting?
No, neither the 52mm nor the 58mm adapter will cause any vignetting at any focal length.

5. How does the lens adapter affect the viewfinder, AF emitter, and flash?
Because the A610/620/630/640 has an optical viewfinder, there will inevitably be some blockage by the adapter. The AF emitter, though slightly obscured by the adapter, seems to be unaffected. The adapter will cause a flash shadow in one corner at the wide zoom setting. See sample above.

6. Can I use a 52mm adapter with a 52-58 step ring to use a 58mm lens or filter?
Sometimes. If you're stepping up to a filter or lens hood, no problem. If you're stepping up to a wide converter, you might encounter vignetting. You will also exacerbate aforementioned blocking issues.

7. I find it difficult to thread the converter onto the adapter, what am I doing wrong?
You'll find that it's much easier to thread the converter onto the adapter (or the adapter onto the converter) before mounting the assembly onto the camera. If you have more than one converter, you might want to get an adapter for each so they'll always be ready to bayonet onto the camera quickly.

8. Which adapter should I buy?
If you're only using filters, a sun hood, a macro lens, or any of the wide converters tested here (except the Canon WC-DC58A .75x), get the 52mm adapter. If you're using the Canon converters or already have 58mm filters or accessories, get the 58mm adapter.

9. Can I use the 52mm adapter with a step-up ring for the Canon WC-DC58A (S2-IS) converter?
No. Besides the possibility of vignetting, the thread on this lens (and its counterpart Canon teleconverter for the S2) is extra long with an unthreaded portion on the end which eliminates the possibility of threading it into anything but the Canon or Lensmate 58mm adapter. Also, remember that though this lens works well at the full wide setting, the zoom lens will crash into its rear element if fully zoomed to telephoto, possibly damaging it.

10. Can I use the 52mm adapter with a step-up ring for the Canon TC-DC58B?
No, for the same reasons as above.

11. Why do I need a polarizer? Do I need a linear or a circular polarizer?
A polarizer deepens blue skies and takes the glare off water and glass. For an excellent comparison click here . The A610/A620/A630/A640 works just fine with a linear polarizer, you can use a circular polarizer but the results will be the same. We sell circular polarizers because they come in silver for people wanting to match their A610/A630 Lensmate adapter, and HMC for people who want a multi-coated filter ( HMC means the filter has 6 layers of a coating that helps keep glare and reflection from getting back into the camera), the Hoya linear polarizer is only available in double coated.

12. Can I put a polarizer on my wide converter?
Of all the wide converters we tested, only three, the Raynox DCR720, Tiffen .75x, and Raynox 6600 have a front thread. Unfortunately, any filter - even a slim one will cause vignetting.

13. Can I put a polarizer/hood on my teleconverter?
Of all the teleconverters we tested, only the Raynox 1540Pro (67mm), Raynox 2020Pro (82mm), Tiffen 2x (67mm), and Kenko KNT-20 have front threads. You can use both a filter and hood simutaneously with these converters.

14. Are there any issues with internal reflections from the inside of the adapter?
No, both black and silver A610/620/630/640 Lensmate 52mm and 58mm adapters have an anti-reflective coating on the inside.

15. Will adding a conversion lens affect how the panorama (stitch assist) mode works?
No because the LCD shows exactly what the camera is seeing with or without the conversion lens.
