I really wish I had kept my NEX-5 to convert. The A100 does a great job, but the live view would have been killer.

Alex H & Micholand - thanks! And, that settles it - I'm doing it!

I guess this is dangerously turning into an NEX-specific thread, but if the moderators would cut me just a little more slack, I have just a few more questions for those with experience:

1. I'm leaning towards a new 5N body for conversion (again, I already have an NEX-6 - which I will leave intact)... 'decent' price seems to be around $400 (body only). Concur/disagree with choice/price?

2. Are the batteries on the 5N and 6 compatible? I could look this up, but I guess I'm being lazy since I have experts reading this...

3. Can the accessory flash that comes with the 5N be used on the 6?

Thanks again, everyone!

1. Choice - good, price - do not know.
2. Yes.
3. No.

  1. $400 new sounds ok; if you don't have a SEL kit lens yet than maybe check the offer for body + 18-55kit (maybe $50..100 more than body only)
  2. compatible, both use NP-FW50
  3. no, the HVL-F7S of the NEX5N uses a proprietary accessory terminal connection whereas the NEX6 has effectively an ISO standard hotshoe

I really want to trade my Sigma 105mm Macro for a Full Spectrum Nex 5N/5 ;)
I always want to try IR Photography, but never get any acceptable result!!!

Thanks again to all. I just won another old Minolta lens (Beercan - let's see how awkward THAT looks on my NEX-6!) for my small-but-growing collection, but still haven't pulled the trigger on the body that the IR-filter-ectomy surgery wll be performed on (although I like the price of the one you linked, Alex H!).

But I thought of another question... I would like to get a really, really wide lens for this setup. Again, desired 'setup' is a NEX-5N body with adapter. Now... If I stick with an A-mount lens (to use on my other bodies), then I'll either have to:
  1. Use my LA-EA2 and put the filter on the front (big end) of the lens
  2. Use a different adapter that allows placement of smaller filters between adapter and lens, BUT ONLY get lenses that have mechanical aperture control

Am I correct? It's late here (Iraq), and I'm probably not thinking clearly. If so, this probably rules out the Sigma 8-16mm I've been drooling over because of the extreme difficulty of putting a filter on the front, and the lack of mechanical aperture control (on the lens) to put a filter between a 'dumb' adapter and the lens.

What do you guys think of the Sigma 10-20 for this purpose? It would fit category 1 above (again, no aperture control), so I would have to also purchase a dedicated 77mm filter for it.
NEX-6 | NEX-3 | E PZ 16-50 | 16/2.8 | VCL-ECU1 | VCL-ECF1 | LA-EA2 | | Maxxum 7 | 50/1.7 | 70-210/4 Beercan |

All lenses compatible with Sony DSLR cameras have mechanical linkage of aperture control between the camera and the body (unlike in Canon EF, where it is electronic). So, there are third party adapters for NEX, that are somewhat cheaper that Sony made LA-EA that allow You to control the aperture of the lenses, including Sigma 8-16, but not very precisely.

I, however, never used such adapters myself, and do not know how they are built inside and if they will allow light-tight placement of filters inside. I see the Kipon-branded adapters have a circular light baffle inside, so they should work well, but they are a bit more expensive.

As I just acquired a used nex 5N (with only 1193 actuations on it), I am converting mine to full spectrum too. Can anyone suggest where to get clear glass for the hot mirror replacement?

The hot mirror in NE5N is thinner than in DSLRs so it will be more difficult to find proper glass.

I have been using NEX3, NEX5N and NEX6 with "naked" sensor for past three years with no problems at all. The sensor itself is covered with another piece of glass that is much harder than the the hot mirror itself and more difficult to scratch.

Thanks Alex H. I guess I just saved some money. I do have another question regarding filters. Is it easier to place the filters in camera body between the sensor and lens or between the sensor and adapter for TP lenses, or is it easier to use adapter rings on the front of the lens?
Also, has anyone used a full spectrum camera for taking pictures under water?

It depends from the lens.
1) If you want to use native E-mount lenses, it is possible to cut the filter square to put it in front of the shutter, but it is not that simple to attach it securely.
2) If you want to use any lenses that require adapter to be used on your NEX, it is possible to put the filter inside the adapter. The way to do it will depend on the filter size and the internal construction of the adapter. I did it many times with different filters (UV, IR) and adapters (M42, EOS, etc).
3) Nothing stops you to use filters in front of the lens, unless the lens has no front filter threads (fisheye), or requires the filter so big that it becomes very expensive.

I can not answer the second question.

Most convenient way is to use lens screw-on filters with the option to change easily between different types such as IR or UVIR-cut.
