Hi Everyone: Just saw a Tony Northrup You Tube in which he says my Nikon kit lens, 18 X 55 can only resolve 9mp in my camera which is 24mp and that because of my cheap lens I am losing effectively 15mp. He says this comes from a DxO rating on the lens. Is this true?
Perhaps we should take a look at the Dxomark report. Clearly lenses are not usually rated in MP; however, I've seen film rated with MP equivalents so their might be some merit to this information.
We all know there are differences in the resolving power of lenses. It seems reasonable that a lens with limited resolving power could compromise the capability of a digital sensor.
Personally, I have found Tony Northrup's information to be useful. Take a look at his credentials.
There are one million subscribers to his YouTube channel, and his book is the No. 2 best selling book about digital photography on Amazon with over 2,000 positive reviews.
Can his huge success be a fluke. I would like to see the video you reference.

GEE, let's see, you spend thousands on name brand camera's and you want to put a CHEAP battery in it.
The 77d does NOT cost thousands!
PowerExtra batteries are not cheap; they are reasonably priced and inexpensive, and they work exceptionally well in my 77d.
The Canon batteries are outrageously overpriced.

I recently (today) purchased a Canon 77d and 64gb Sandisk from Amazon. Great deal -- $588 for both. However, I held off on buying 2 LP-E17 batteries for it for the following reason..... every off brand battery came with its own charger (which I figure I should not need) and which stipulates that they will not display on camera how much charge they have and that they must be charged with their own charger. No batteries seem to be sold without their included charger. Only Canon batteries seem to be available and they are very expensive. Any advice on this ??

I own the 77d, and I use the PowerExtra batteries. I don't even use the LP-E17 battery that came with the camera.
The PowerExtra batteries work perfectly and have a much longer charge life than the originals.
I bought two batteries and the charger from Amazon for $18.99.
My 77d displays the battery's charge status. I highly recommend these batteries.

Don’t know if I had a Gas attack but I went and purchased a new lens today for my Nikon 7100 .... a Sigma contemporary 150 - 600 F 5-6.3 Included in the purchase was the case, lens hood, tripod collar, dock station, a protected lens filter.
In addition I picked up a Sigma 1.4 lens teleconverter, a Pro??? Tripod/monopod and appropriate “L” mounting brackets for the camera and lens.
Hopefully I got all the bases covered now as I still have the 2 kit lenses that came with the camera and have served me well.
Looking for your opinions. Did I do right?
I pick all up on Wed at the local Camera Shop.

I'm curious! Why didn't you ask your question before you made your purchase?
Are you looking for approval, or did you think someone might have dissuaded you?
I'm sure it will work out just fine; enjoy your purchase and happy shooting!

I would love it if camera maker allow me to program the full AUTO mode myself. I know very well how I would approach to these settings and if I can put my algorithm in the camera I would use it almost all the time. I actually like automation because my job is to automate industrial production machines. However, I ended up using my camera in manual mode so often because I just can't make it to work my way.
On the surface this sounds like a good idea; however, no algorithm, yours or anyone else's can apply to all situations.
While I don't use full Auto, I am an experienced photographer and have played around with Auto out of curiosity (Canon 77d). I've found that it does a relatively good job most of the time, but a computer can't read your mind or understand your subject or how you intend to treat that subject.
No fixed algorithm can anticipate situations requiring a particularly fast shutter speed or a demanding aperture requirement.
A good learning tool is to take shots in Auto and examine the histogram and other exif data. This can help the inexperienced get a feel for exposure settings as they relate to subject and lighting.
My own personal preference is aperture priority with auto ISO followed by EC if necessary.

Thanks, and that is why my question. Many books, but which are worth the read and study?
You could always read the reviews; many are quite impressive.
Here's one of the many 5-star reviews.
"Excellent book on Macro and close-up photography. Goes into detail on equipment and technique which I needed help with. If you enjoy close-up or Macro photography you can't go wrong with this book, well worth the price."

Are there any books on Macro photography that are worth me buying/studying?
Total newb here with new Sigma 105 f/2.8 lens.
Have been shooting, but need some basic tips
I just checked Amazon; many, many books available on macro photography.

The man is trying to learn how to use his T6, and everyone is going on and on about the grey card. I don't think these lectures are helping.

Wow - this has been a challenging journey so far. I have used a point and shoot for 40 years and recently bought a Canon T6 to experience the joy of creating certain types of photos that I see others capturing but I have to say there is a big learning curve. Over the last couple months I have stalked this site collecting as much information as I could absorb and I have to say it has been a treasure chest. Between this site, YouTube and some online classes I am just now starting to feel like I am beginning to understand the basics of exposure, lens physics, camera settings, composition, etc. Believe me when I say that I know I have a LONG ways to go but it is nice to actually see some progress on my understanding of some of the basic elements. However, I now have a couple questions. First... I am currently learning about using an 18% gray card for determining correct exposure and I think I understand that this card is 50% black and 50% white mix which makes a great color for setting an exposure so that the histogram can be centered but why is it called an 18% gray if it is right in the middle between white and black? Second question is do any of you use this method of setting exposure or do you rely on the internal light meter in the camera? Is there an advantage to using a gray card? I really hope this post makes sense - like I said before... I think I am getting a handle on some concepts but being a newbie I might be way off and not know it. I pray that you will allow me a measure of grace until I can get up to speed.

Cavik,
I moved into digital photography in January with the T6 after shooting film for 60 years.
Much of the advice you can find here has merit; however, I suggest you read the PDF manual for the T6 AND get a copy of David Busch's fine book:
https://www.amazon.com/David-Buschs-Canon-Digital-Photography-ebook/dp/B01KNT34O6
It did wonders for me and countless others; it's a superb investment. In addition to making you intimate with the features and use of the T6, you will learn a great deal about digital photography.
Good luck in your new venture.

Just had to say the 77d is a great camera.
I bought mine via Amazon back in July when it was on sale for $649.
Get one with the USA warranty for peace of mind.
Amazon still has some good deals.

I am considering purchasing an 85mm Sigma Art lens for use on my canon cameras. Does any one have experience with this lens or other Art lenses ? I would appreciate all feed back before I make this purchase.
Thanks in advance

I have three Sigma lenses for my 77d, and they all perform superbly!
They are 17-50mm f2.8, 30mm f1.4 and 10-20mm f3.5.

Not that it really matters at this point but the 77D and the 80D do not use the same image sensor. They are very similar but they are not the same. Canon is constantly working on improving their image sensors while trying to keep costs competitive. The image sensor in the 77D uses newer technology than was available when the 80D was introduced. The newer sensor technology coupled with the more advanced digic 7 processor and software make the 77D the better choice if going for better image quality alone. That plus cost also make the 77D quite attractive. But, the 77D is still the top of the line Rebel, not that there's anything wrong with that. The similarly in the image quality plus additional functionality very well may make the 80D the better choice. Me personally, I'm waiting for the 90D to hit the streets.

Agreed!
I bought an EOS 77d in July, and I am delighted with the image quality, fast focus and countless features. The LiveView features are incredible. The low light capability is remarkable, and the Multi Shot Noise Reduction feature really works well.
Great camera: especially with my Sigma lenses: 17-50mm f2.8, 10-20mm f3.5, 30mm f1.4 and Tamron 70-200mm f2.8.
I always enjoy hearing praise for the 77d; thank you!

2. 16xAPS-C for 80D or APS -C Image Sensor for 77D ????
3. 1/8000 to 30 sec for 80D and 1.4000 to 30 sec ???

A new camera won't give you "better" pictures!
However, experience, knowledge of Photography, understanding your camera's features and abilities will. Clearly, an artistic eye helps.
With that thought in mind, the 77d is an excellent camera. The DIGIC 7 processor is superb. The desirable features of the 77d are vastly imoroved low light performance (offers the opportunity to shoot at faster shutter speeds), super fast, improved AF system and a top quality 24MP sensor.
The 80d does have the 1/8000 shutter speed, but I doubt you would ever use it.
The 80d will cost you more and will offer you very little in added features or benefits.
Also, the 80d is heavier.
I own a 77d, and cannot be more enthusiastic in my recommendation.
