Re: Have quality standards changed on here recently?

I'll chip in on the issue of blurry images because I feel it perhaps needs addressing.... I see quite a few genuinely blurry shots in the feedback forum but some the screeners claim are blurry puzzle me at times; not because they're succinctly blurry but because it's impossible to tell at the (mostl...

Bad light making correct exposure tricky (i.e. likely to draw a 'dark' rejection in its current state). Looks soft too (at best — maybe even blurry but impossible to tell at that size).

Essentially both crops work here but but neither image has the quality to pass screening. Both are noisy, need levelling and suffer from general quality issues, and the second would also need a better (tighter) crop.

They do look slightly blurry to me to be honest but the originals will tell you for sure. I've said it many times but you can't properly determine blur from a 1200 pixel image. If the original is blurry, then the edit will be too.

74mm on a crop body for a 738 is pretty close, however still not close enough to eliminate haze after around 0800. Sometimes there's just no way to defy physics.

Are you test shooting indoors or in bright sunlight? If in sunlight and you're not on auto ISO(?) there's a rogue setting somewhere that needs sorting. Select a semi-auto mode (or manual) and set the ISO yourself, to 200.

Re: constructive criticism please

They don't generally look too bad but the conditions are against you. At this time of year heat-haze is a problem at the times you're clearly shooting (light is harsh, giving nasty contrast) so my only advice would be to go out either early morning (sunrise-0800) or evening (1800-sunset).

Don't take DXOMark too literally as it's all theoretical. Basically the more megapixels your camera has, the greater the pixel density, meaning the lens has to work harder to get the best out of the sensor. In theory, when using the same lens, you will lose sharpness with the 7DII compared to the 7D...

Auto ISO kind of assumes you've got the world's unsteadiest hands and so over-compensates by selecting an often ridiculously high value.
