About 6 months after buying my 7D, I got the associated battery grip for it, and my feelings on it are mixed... As others have said, at times, the duplicated buttons for portrait orientation can come in extremely handy. Not only do they allow you to operate the camera in portrait mode without craning an arm over to reach the normal buttons, but because of ...

Although only the manufacturers themselves know for sure and there could be different reasons from one manufacturer to the next there are two obvious possibilities that receive most of the attention from the users of cameras and their proprietary batteries. Profit. Limiting the amount of competition in the marketplace by not using standard, off the shelf ...

Partially functionality and partially profit. With my Canon 5D Mark iii, I use a battery grip. The battery grip provides two power options. One, I can use 2 of the typical Canon proprietary battery packs in parallel or I can use 6 AA batteries that take up roughly the same amount of space. When I use the AA batteries, the camera performance suffers ...

Good things are not cheap and cheap things are not good. This is true of all lens manufacturers. There is a small premium for brand name lenses usually but price is largely proportional to quality. For example, Sigma produces plenty of cheap low-quality lenses but they also produce some excellent lenses and, guess what?, they are far from cheap. When ...

When comparing lenses, it is important to look at all the qualities and features. In this case, those really are not comparable lenses. The Sigma is their base line, whereas the Nikon is a stabilized, internally focusing, high quality glass lens. The Sigma would compare better to this lens from Nikon, also compatible in price. When comparing lenses, its ...

But if you buy a 3rd party lens then theoretically it could stop working tomorrow. Only if you try to use it with a camera model newer than the third party lens. If it worked with your camera when you first got it, it should continue to work with that camera. There's really no additional risk that it will suddenly stop working with a camera with which it ...

I have a Canon 600D and I've purchased a third party (Travor) battery grip for it as well. I think it is the best accessory I've purchased for my camera yet. I does everything that Mike said in his post "So, the pros are that it allows easier, steadier camera use in portrait orientation, balances the camera well, and gives you longer shooting time with ...

Great question! The best way to think about the workflow is by understanding that Lightroom doesn't edit the RAW file. Instead, Lightroom saves a series of alterations that it has applied to the RAW file, hence non-destructive editing. The RAW file itself is unaltered and Lightroom is saving the adjustments in its own file. When you export to make changes ...

The battery being 3.6 gives it away. It is a lithium battery. Lithium batteries are dangerous, they can explode if not charged correctly or protected from physical damage properly. You don't commonly get AA sized lithium rechargeable cells either, they tend to be a little larger to accommodate protection circuits. In order to allow the use of high capacity ...

There is actually an OEM Canon ultrawide zoom lens that costs less than all the lenses you're looking at. That is the EF-S 10-18 f/4.5-5.6 IS STM, which is the low-price alternative to the Canon 10-22. Yes, the Samyang and Rokinon (and Vivitar, Pro-Optic, Opteka, Bower, Phoenix, Walimex, etc. etc.) are the same lens, and are optically identical, although ...

They are not more expensive just because they are proprietary. They use a different technology which performs better with the flash's large bursts. Lithium-Ion as opposed to Ni-Cad or Ni-MH. You can get non-proprietary Li-Ion batteries specifically for cameras.

The Tamron SP 85mm f/1.8 Di VC was introduced in 2016. The Nikon 85mm f/1.8G was introduced in 2012. Most lenses settle into a lower street price a few months after their introduction than the price they command when first introduced. It's still very early to see where the long term price of the Tamron will settle. The most obvious difference is the ...

They're going to test the hell out of that stuff! So do all lens manufacturers. It's not like Sigma (or any other) is going to gamble when releasing a lens. If your favourite 3rd party lens suddenly stops working If a lens suddenly stops working, it's more likely due to some hardware failure of the lens instead of the lens becoming incompatible with the ...

It's the same reasons why someone would take over a small country: control and power :) Control: A manufacturer can achieve their own custom compromise between size and capacity. They can tailor the size and shape of the battery to the camera casing. They can achieve an extremely high reliability rate and consistent capacity. This last point is crucial. ...

If you're talking about manufacturer-specific batteries (excluding third-party ones), then I can think of at least one exception: Ricoh is using the same battery in their GR/GRD/GXR series as Sigma's DP Merrills. If you're talking about the different-than-AA physical sizes, then I think it really boils down to: Form factor (those slimmer-than-AA point-and-...

TL;DR: It depends on the age of the lens and whether or not you can update the firmware. In reality, how common is it for a 3rd party lens to quit working due to an incompatibility? ... For that matter, what's the worst thing that can go wrong with a lens? Presumably a total communications failure would mean the camera doesn't know what lens it has and ...

I have been able to try the Canon 2x III extender and Sigma 70-200/2.8OS combination and they do mount and autofocus on the Canon 70D and T5i. The resulting image quality, unfortunately, is beyond the scope of what I can test.

I always though I needed one so I finally got one. After reading many reviews I decided to save money and get an aftermarket brand. The look and feel of the grip was great and matched my camera nicely but I soon noticed that the grip was draining my batteries even when the camera was in the off position. In 24 hours my batteries were completely drained ...

For the 600D, I would say, yes it's worth it. I have a 7D now and do not use a grip, as it makes the camera too heavy and bulky, but back when I started out with a 450D I had the battery grip attached to it almost permanently. I think the primary thing it did for me was make more comfortable to hold, as it was a smaller sized dslr. I also liked the extra ...

The edited question: "Does the higher price lens always reflect better quality regardless of it being 3rd party or not?" can be generalized for any product: Does the higher price product always reflect better quality or not? The answer, in general, is "it depends" Sometimes higher prices reflect higher costs (better engineering, better material, better ...

I've got Zeikos grips for both my 5DII and 7D. They work fine. Sometimes I have to wiggle the right hand battery in the one for the 7D to get the camera to see it. Once the battery is seated, the camera sees it, and the door to the battery compartment is closed I've never had it stop being recognized until the battery is removes and reinserted. The build ...

There are a few aspects to this question. Physical connection: will they mate up and connect to the camera and operate? Almost definitely, sometimes with some limitations (and occasionally with some extras: the Kenko teleconverters connect in with Canon lenses and allow them to autofocus at F8 instead of F5.6, although I found the actual use in the field ...

Hard to tell. Canon's 2x III teleconverter includes a rubber extension that fits in to the back side of a lens mounted on it. This is used to block out excess light (that would have been for the outside edges of the image) from making it in to the teleconverter. It also likely would not support full electronic control of a third party lens. To maintain ...

I'm not aware of any third parties making Q-mount lenses. Speculating not very wildly, the relatively tiny market for the Q, the significantly different sensor size and the need for the in-lens leaf shutter for Q mount lenses all make it not an attractive platform for third parties, so I wouldn't expect this to change any time soon.

Most of these answers here so far have avoided answering the question. One person alluded to the answer, greed! There is no reason whatsoever why the camera manufacturers couldn't come up with a standardized specification for a smart battery listing all their specific requirements, including a general size, and then put the specification out there for ...

I know its starting to be an old post, but ive had the 10mm 2.8 Samyang lens. I will recommend it. Its just an amazing lens. Ive used it with my canon 70d.

They make the MB-D15 http://www.amazon.com/Nikon-MB-D15-Battery-Pack-Digital/dp/B00BJ3NGFS I have one of these and love it. The challenge/benefit with third party ones are: Challenges: Can be lower quality. Check out reviews. Generally people like Photix grip. Benefits: Lower cost.

I think the Profit reason is without merit - See Why do Flashes not use Proprietary Batteries?. We also have no scientific reference explaining why proprietary lithiums would outperform AA lithiums or AA NiMh in any way, but we do have anecdotal evidence that they provide for a snappier/more responsive camera. Also, for small cameras especially, the form ...

Additionally, custom batteries can allow the manufacturer to create a battery in a custom shape and/or size that may not be available using commodity cells (AA, AAA, etc.) Lithium batteries typically have a higher change density than NiMH and NiCad. All other things being equal, that means a Lithium battery can be smaller than an equivalent NiMH/NiCad. ...

NiCd and NiMH batteries suffer from a serious issue called memory effect. This renders battery capacity much more worse after recharging than Li-Ion batteries. To prevent this, you have to exhaust the battery before recharging, which is not expected in most situations except in some professional environments. For example when you're going on a trip and you ...
