Canon EOS 7D Mark II Tutorial - Tips and Techniques 

I am crying because I don't get it

Canon 10-20mm is an excellent men we for ultra wide to wide angle=(16mm-32mm) with crop factor figured in. Canon18-135mm nano lens is the sharpest 28-135 range Canon makes. And it is a lens that would be considered a all in one lens with range from ultra wide to telephoto. There are however other choices like a portrait lens in the fixed focal length of about 100 mm 55 -65 focal length crop factor included. Canon makes several 50 mm lenses with apertures ranging from 1.1,1.4,1.8 depending on your budget. They make macro lenses 50mm - 65mm that are very sharp plus these lenses could be used for close ups of rings ,flowers and the like. You can pick up all these lenses used and save money. B & H, Adorama and Roberts Camera used photo pro in idianapolis In. Has the best warranty six months. I purchase 90%of my used gear thru Used Photo Pro. Also when buying your speed light get the Canon 600 ex rt (first or second version) or 430 ex rt iii,they both are radio triggered and the 430 ex rt iii can even be set as the master over the 600 ex rt. They even carry these speed lights used at times.

At 600mm everything is magnified 10x on full frame so fast shutter speed and steady tripod is a must also turn off image stabilation. Atmosperic haze can also blur images as ever thing is magnified so images at far distances can be affexted by pollen , heat .....

I agree with what previous poster said. If shooting hand held, which I have done often, you must develop the correct skills in properly holding and shooting with a lens of this size. Just takes practice. Use image stabilization hand held, turn it off if using tripod.

Apart from the lense issue the 7d mkii is not a very sharp camera as it seems to have a very aggressive AA filter.
