grainy raw files with brand new 5D Mark IV

[depshado]

I have been trying different lens and my photos are no way near as good as my Mark II. I am very disappointed with my purchase of this Mark IV after hearing so many reviews of how great it is I have yet to see a landscape or wildlife image that comes close to my Mark II.

I can't upload an image(raw file because a file is too large)

great detail

"Thank you for the advice on my Tamron lens..."

You are certainly welcome. I hope a bit rubs off and helps you some. I have tested the big Tammy G2 150-600mm, new model,  it is in my opinion the sharpest of the bunch right now. If you need any, and I can help, tips on LR let me know.

Always remember the camera is basically a storage device.  You and your lens tell it what to store.

I had a Mk II and I loved it. I had a Mk III and I loved it, too.  I retired before I could love a Mk IV !  There is no doubt you will love your Mk IV.  As far as taking pictures it is probably a better choice than any of the 1 series cameras are.

Although they are just storage devices there is a bit of gadgetry going on inside.

Ernie captured beautiful detail with his hawk capture, it is a great image!  In my true professional setting as a marketing prof I taught retail management early in my academic career.  The answer to the question of: "what are the three most important attributes in determining the profitability of a retail store" is the same answer to the question of what are the three most important attributes in capturing a good wildlife (or sports) photo, LOCATION, location, and location.  Nothing beats being close enough to a subject that you aren't at the limits of focal length and with poor light placement.  Location really constrains what you can do in terms of framing and other aspects of the capture decision.

But often a lot of cropping is required and when that happens, an exposure triangle that keeps you at the lower end of the ISO range is going to be extremely helpful.  The hawk below was shot from much further away than I would like but I could sense he was skittish.  When shooting wildlife I will often get a couple of captures as soon as I am in reasonable range and then try to sneak into a more optimal location but Mr. Hawk was pretty much through with his meal and as soon as I moved from my initial location he took off.  I shot this at ISO 250 with a 1DX III and EF 400 f2.8 lens plus 1.4X extender resulting in a 560mm f4 combination that put me at ISO 250 with my selected 1/1600 shutter speed. 

The first image is a 6.5% crop from the frame, the second is the complete frame down sampled to fit within forum posting size limit.  With a low ISO, you can take a pretty severe crop and still retain quite a bit of detail.  Closer would have been MUCH better but this gives you an idea of what you can do with cropping when the lower ISO lets your sensor produce its best.

Your eagle's slightly out of focus. There's no sharp point, and this is a common issue with the 5D Mark IV that I am trying to get them to fix. Shoot through your LCD (rather than viewfinder) to see the difference.

This is soft and has minor fringing on the beak and branches. A better lens might help!

"There's no sharp point, and this is a common issue with the 5D Mark IV ..."

There are only two factors that determine IQ in the sensors ability to capture a photo.

Resolution, which relates to pixel density, pixel size and capture of fine detail. And, secondly, sensor uniformity, meaning the extent to which QC can eliminate errant pixels and manufacturing flaws. In both these specs the 5D Mk IV excels with its 30MP sensor.

"... I am trying to get them to fix."

However, where you go wrong is resolution and color accuracy is also dependent on the lenses used. In others words use a poor lens and the sensor can not reach its full potential.  Some lenses are not designed to fully exploit the potential of a 5D Mk IV. In the case of the eagle shot the lens used is the best lens made in the 800mm FL class. This brings us to critical focus which is the biggest single challenge of all.  Again, not a 5D Mk IV issue but a human issue.
