Thanks for the advice, I need it.

I put it in Shutter priority mode, so it picked the aperature/iso for me. I put the AF point in the center dot only.

It was pretty bright outside, so I was expecting a lower ISO to be honest. 

Guess I should have put in manual mode. Smiley Happy


The shutter speed is whatever works for you.  For a moving car I think 1/100 will do it for me.

 

Getting ISO 200 in bright sunlight might be because you have "Highlight Tone Priority" option set.  You can tell via the viewfinder if the symbol D+ is shown.  When activated, the minimum ISO is 200.  This option protects your highlight area from being overexposed but the ISO cost is too high. I always have this option off.

Good call on the Highlight Tone Priority probably being on.

Re: Need help choosing lenses for 7D Mark II

Well that's true, I keep forgetting to take ISO off of auto... Eventually it will sink in.....

 

The camera is a EOS Rebel XSI and the lens is a 100mm, 'macro' ef 100mm 1:2.8 usm

 

I do have another lens: efs 18-55mm IS, maybe I should try that one as well to get a little wider area to work with as I get the hang of panning.

 

I'll check the highlight tone priority to see if it's on.

 

Thanks!

"But, I'm not so sure if they could capture that much detail and contrast on the same gray, overcast day,"

 

Believe me they can.  The Tamron is so very close to the Canon it is scary.  It is a 'best buy' considering the cost vs performance.  Just don't try to kid yourself both of those entries are very good.  This comes form owning all of them and using all of them...........a lot.  IMHO, the Tamron is better than the Nikkor which more than doubles its price!

 

"I know for sure is that 70-200 sure outperformed my 24-105"

 

Of this there is no doubt.  But the ef 24-105mm f4L is not a stellar performer in the least.  It is the 'best buy' in a Canon L lens though but not even close to the best IQ.

 

After thought, I actually prefer the Tamron on my D3 and D3x over the Nikkor.  I rarely use the Nikkor.  It is not a true 200mm lens ending somewhere near 180mm.

Tamron lenses continue to have problems with hunting in low light. What good is having a constant aperture f/2.8 lens when it constantly hunts in low light.  Yes, Tamron has great image quality, but, no thank you.

You have never used one!  Have you?  Have you ever even handled one? Mine doesn't have any such issues.

You should really have some hands on experience before you make such claims.

 

There is no way I would give up my Canon ef 70-200mm f2.8L II but I can afford it.  If I couldn't, I would have no hesitation of using the Tamron exclusively.

Yes, I have, and I stand by my statement that their focus performance isn't anywhere near that of their Canon counter parts.

That's not what you said first. I agree with that statement.  But I would hope so for nearly a thousand bucks more.

It is more better to use the gear yourself instead of just read inter web reviews.  Picking up a lens and shooting a few shots is not nearly "using" a lens.

 

The bottom line is both the Tamron and the Sigma are extremely viable alternatives to the Canon for folks that don't have $2000 to spend on a lens.  The Tamron is the better of the two, however.

For the record, the shot of the 105mm Howitzer was 1/640, f/2.8 ISO 200.  I was using Av mode that day, and had dialed the ISO up to 200 because it was moslty so dark.  Most of my shots were 1/320 to 1/800.  Some shots were faster, and some were slower, depending upon what I was shooting, and mostly how much sky was in the background.

 

The Image Stabilization on the Canon 70-200 f/2.8L MkII is excellent.  Anyone should be more than pleased with it.

I have used both the Tamron and Sigma versions of the lens. And I still own a Sigma 70-200 f/2.8 HSM. I would pick the Sigma over the Tamron any day because the focus performance of the Tamron is low light (where you need an f/2.8 lens) is crap. If you still own your Tamron go out and test it in low light conditions, your opinion of the lens may change. I had a good opnion of the lens until I tried using in lighting conditions where you really needed and f/2.8 lens (i.e. 1/500, f/2.8, ISO 3200+) in those conditions it just constantly hunted back and forth. Both the Canon and the Sigma perform fine in those conditions.
