Question: Does it come with both battery holders (MS-D14 for AA and MS-D14EN for EN-EL15)?
Document: When you purchase this grip you will have to purchase an extra battery for the grip BUT it does come with two batteries trays one for the EN-EL15 battery (like the one that came with your camera) and a second tray for 6-AA Batteries (Note that if you are using AA Batteries it will drain the batteries quickly) but its there for when you are in a fix and need to get a few more shots. When you are using 2 EN-EL15 batteries you basically almost double your shooting capacity.
I will not spend time bemoaning the fact that this product is $269....I prefer to read useful information related to the product itself. The MB-D15 is well constructed, and gives one the option of using AA batteries in addition to the EN-EL 15 Nikon battery. This battery grip is great for people with large hands who appreciate the added gripping area. I prefer to use Nikon products with my Nikon cameras and don't mind paying the extra (nominal) cost.
An investment into my D7100 system that provides a great feel and strong grip in the vertical format. Also adds just a bit more room for a comfortable horizontal hold. All the buttons have good positive responses and the toggle has strong click points for navigating.Yes, it cost a premium price but I can justify it by saying I have added to my camera system and protected my Nikon USA extended warranty  should anything happen to my camera while operating with the grip. The fit is perfect as one might expect from Nikon and the weight is not all that bad for adding an EN-EL15 battery within the magnesium case of the hand grip.I looked at about a half dozen after market clones of this MB-D15 battery grip and read many reviews about poor quality, flimsy construction, thin plastic etc but;I have none of those worries with my Nikon battery grip.
The grip seems like it's made alright. I just cant believe that for $269.00 that it doesn't come with a battery. It would have been nice if it had said that in the description somewhere. One would assume that something called a "Battery Power Pack" would come with a battery... My fault I guess for not doing my DD.
Adds a little weight when it's full if AA batteries but less with camera battery.It's nice having the extra battery. I feel like I can grab my camera and it is always going to have power, right when I need it.
Don't waste your time with third party grips. I've tried others and they just don't come close to matching the build quality of the authentic grip.There is nothing wrong with this grip. It's perfect. Ignore reviewers who gripe about it not coming with a spare battery. That shouldn't affect the rating of the actual grip. This does what it's supposed to do better than any third party grip. It's nice to have a grip that matches the D7100 in look, feel and texture.
Buying a second battery just to put it in this grip is fine if you like the extra heft the grip offers.But other than heft, it doesn't do too much; the main benefit is the additional AE-L/AF-L button on the grip can be assigned a different function to that on the camera - handy for a specific AF-ON assignment.You have to carry the second &#34;cradle&#34; if you want to use 6 AA batteries.Having said this, it fits flush to the camera and looks the part.
Perfect for over sized hands. Holds the extra battery, and can also utilized AA's as well! Fits perfectly on the D7100.
The Muiti Battery pack for my d7100 works great and I love the way the Nikon reads the battery so you can pick what battery will use first.
The battery grip works well and fits well. The only complaint is the design. I dont understand why they designed the product where you have to REMOVE the battery grip to gain access to the second battery. WHY? !
Answer: Yes.
