that was the reason why I initially bought the infrared remote release ML-L3 Nikon. If you have a Nikon camera, has not taken the worst choice so certainly. I also think about the lenses from Nikon, which are very cheap and of high quality for a APS-C format camera. Unfortunately, this does not apply to all of the accessories from Nikon. Used for the telescope or macros you absolutely need a remote release. With the ML-L3 infrared trigger me was that at Astro shots but too fiddly because the camera reactivated after a period the normal trigger and I then had to go to trigger the camera setup menu each time. Even the infrared trigger was my opinion from a processing perspective, not. In the usual Nikon quality, but it does the job The Cable Cord MC-DC2 is slightly better processed and it also does the job, without having to intervene in the camera settings. It's a button with a pressure point before the trigger point, which you can lock also has an integrated slide for long exposures. So to make good use of Astro recordings. For a simple switch with a cable and a plug part, however, is relatively expensive (just under 24 on 23/03/2014) and I were not such a miserable original part enthusiast, it would probably have also done the accessory cable release for 12, but that's my problem. When shooting at the telescope or from the tripod from the MC-DC2 is me in good stead. A star deduction for processing, the price and a little too short guessed cable. Four stars for a working, practical Nikon original part made in China ;-)
