Canon 5D Mark IV vs 5D Mark III - ISO & Dynamic Range Test 

Madison Alexis congrats Madison

+Uptown Wedding Photography NJ I have mostly N scale. My Dad was a train nut. Unfortunately having grown up around trains and literally having half of our living room and my bedroom as home to various train layouts as a kid I got burned out on model railroading at a young age. I still keep a few on display as a reminder of my dad who passed years ago. But I just dont have the time or patience to do a proper train layout anymore, and my dad would never accept me not doing it right lol. I finally convinced my mom to sell much of his collection, so ill be busy posting on ebay next month. It only took me 25 years to convince her she should sell most of this stuff and take a vacation with the money rather than leaving it for me to one day inherit and eventually sell to buy more camera gear!

I see...It is hard to tell on a video if N scale or HO gauge unless something in the photo to give it scale...Either way, always cool to see some nice models, especially love the Big Boy. I used to own an HO version years ago, but because I was building a Colorado type mountain railroad it was just too big so I had my dad trade it for some smaller steam that looked better on a mountain railroad.....Thanks for responding...

Great review!! The same here I'm gonna wait until the Mark V comes out! Mark 3 it's enough for me! I love the 135 and the 50 F1.2 I just need a 85! That's all for portrait! What do you think about the new sigma 85 Art ? Or should we wait for the Canon real esse a new 85 1.2 or 1.4 should be better then the sigma!

+Pedro piragua I have never had the privilege of using that lens, but I drool over it at least once a week when I'm looking around for bargains online. Honestly this is the lens I want the most. I may rent it in the next few weeks, but it's a pricy rental item.

borrowlenses.com have 7 day rentals super cheap. Less than $150

Nikon D850 would be a superior cameras in some areas but keep in mind that if most of your photography is gonna be handheld then the lower megapixel will be an advantage since higher megapixel is less forgiving and will produce less sharp pictures if tripod is not used.

+Pedro piragua to be perfectly honest I don't see much reason in your situation to upgrade unless you have to buy a new camera. If i needed a camera, i would buy this over the Mark iii. But i would not buy it just as an upgrade. I just don't see much reason. Unless you want wifi to transfer pictures and post them right away there is not a lot I can think of as a wedding shooter that would change much. For me shooting sports the improved af is great. I also like the fact it will autofocus when shooting video which is great for someone like me who is not a serious video shooter but on occasion has to shoot video. As much as I like the camera, i dont feel compelled to buy it right now. Maybe when I need a new full frame I might buy it. But at $3500 it just doesn't justify the cost to shelf my one year old Mark III. The image quality real world, is nearly identical in print or on the Web, most people will never see the difference. Even holding prints side by side, my family members said the pics looked exactly the same between the Mark iii and IV. I struggled to tell the difference. If nothing else I would wait for the price to drop in a few months.

Hi Vincent, Thank you very much for your opinion and response. It helped me to justify not upgrading to another body . Thank you very much.

+Steven Scholten when I cropped in the Mark IV still looked just a little cleaner on the computer screen at full resolution. But in print it was insignificant in my opinion. And a Web sized image showed even less of a difference. In addition to cropping I also resized the images to 8mp in Photoshop and came to the same conclusion. You will see a slightly sharper image with slightly less noise on the Mark IV, but it is not something most people will see in my opinion. A full resolution image Zoomed in 1 to 1 on a computer on a high resolution monitor you will see a difference, but not in print or on the Web. I did not specifically check and compare how Lightroom handled the noise side by side but while editing I did not notice much difference in how Lightroom handled the noise. Maybe this weekend i will go back and check that. Unfortunately, the first two weeks I had the camera the Raw files were not supported by Adobe, so most of my editing was either Tiff files I converted using Canons software or JPEG'S. But the last few shoots I did I was able to use RAW files and did not notice any difference. When I do my full review this weekend i should have a definitive answer for you.
