Any limitations on using filters on the P7700?

Does anybody know if there are there any weight limits or similar limitations on attaching filters to the lens. I have a set of Cokin filters that I would like to use. This could include a step up ring, the Cokin holder with polarising and ND filters.
I am concerned about pressure on the zoom mechanism.
Many thanks
John

Your user ID and your question indicate that you are interested in safety and security.

I don't know of where information about how much weight can be safely mounted on the end of the lens can be found.  I wouldn't put more than 4 oz. (about 113 grams) on the front of mine.

So far I tried the Canon 250d close up lens and the Raynox 250d and have had no problems. There is a step ring in between as well. Don't forget to take the lens ring off first. Good luck.

Re: Any limitations on using filters on the P7700?

Raynox type devices attach to a tube which screws onto the body (remove the collar around the lens first). The lens moves freely inside this tube, so there is no risk of damaging that. Of course the resulting assembly is no longer pocketable but ...

Not sure how much the combination of Cokin filters weighs - I will have to check it.

I've had a "google" and found a couple of US sites with these on but when you look at delivery/tax etc. for mailing to UK it works out around $85US. I haven't managed to find a UK based supplier.

Nikon do not as yet have one available.

Re: Any limitations on using filters on the P7700?

Here's the response I just got from Nikon Support on this issue which I didn't find helpful at all.

"If you are querying attaching filters to a Coolpix camera, as the lens extension is more delicate then the DSLR lenses I would not recommend attaching a filter directly to the lens itself. There are some third parties who have an adapter system that attaches to the body of the camera and does not actually touch the lens and I would look at those. Unfortunately as these are third parties I cannot recommend any or confirm compatibility as Nikon does not test third party items."

Bit strange considering one of the selling points for the P7700 was the ability to mount 40.5mm filters.

Bought my adaptor tube from Amazon.co.uk, it is made by Polaroid and says it is for the P7000, cost less than £10. The Raynox thingy was about £35.

However, that Nikon representative did not specifically mentioned Coolpix P7700 as he/she is talking of Coolpix line in general.  Is the P7700 the only Coolpix with the ability to accept filters? Is it reasonable to expect that Nikon representative is unfamiliar with P7700?

Nikon does sell lens hood and a UV filter for P7700, then one of Nikon staff does nor recommend to get them?

Latest from Nikon support ...

"In relation to the P7700 specifically, there is only one filter which we recommend attaching to the lens which is the 40.5mm NC filter. If you are looking to use other filters Nikon recommend attaching the lens hood HN-CP17 to the camera and 58mm screw-on filters can then be attached to the lens hood.
There is no weight restriction on filters that I can advise you on as we do not have that kind of information I'm afraid. As filters are generally quite light I would not foresee an issue and attaching them to the lens hood eliminates any pressure on the lens itself."

Seems fair enough to me

Hi John.

I don't see how the pressure on the lens itself would be eliminated by attaching filters to the front of the lens hood (which is otherwise obviously OK - the lens hood is specifically designed to support a 58 mm screw-in filter). I mean, the lens still has to support the weight of the lens hood + anything you may attach to it. So in this regard I find the reply you received from Nikon strange. Attaching filters directly to the lens (using a step-up adapter rings) produces less radial stress than using the lens hood since the weight of the filter would be closer to the lens than with the lens hood. Step-up rings are both shorter and lighter than the lens hood.

If you intend to play with step-up rings and such, don't forget to remove the protective ring around the P7700 lens first! (there is a warning about this in the manual as well).

By the way, I have the lens hood (not the original Nikon one, a JJC knock-off) and both a 40.5 mm and a 58 mm polarizing filter. So I tried these two combinations:

  1. camera + 40.5 mm CPF + lens hood
  2. camera + lens hood + 58 mm CPF

Both combinations worked. The first combination seemed like a good idea to me because the polarizer itself was also shielded by the lens hood (less chance for flare), but I got slight vignetting with it at camera's widest setting (at 28 mm equiv.). There was no vignetting with combination 2 (my 58 mm filter is thinner than the 40.5 mm one, so I am sure this is why). But this indicates that stacking two or more filters to the lens hood would certainly produce vignetting. This is another reason why I would probably opt for a step-up ring if I wanted to experiment with more filters.

But the safest option would be to get the extension tube which attaches directly to the camera body.

Kind regards, T.

Re: Any limitations on using filters on the P7700?

Thanks Tom for the response and info on the combinations.

The step up ring arrived today so I have tried the Cokin set up and I think that there should be no problems as I would think that they are lighter than the lens hood/58mm filter combination. The only issue may be having to take care when rotating the Cokin holder as it is a bit stiff to turn.

There is no vignetting at the wide end either with the step up ring attached direct to the lens. I did try it with a 40.5mm filter on the lens first and did get some vignetting then. I thought the idea of having the step up ring attached to the 40.5mm filter would be good because you don't have to remove the protective ring from the lens housing as there is plenty of clearance.
