I have a Canon 24 to 105 f4 (original version) that I bought with with my 5D3 about 6 years ago. The focus at low f-stops is starting to look soft as compared with my Canon 70 to 200 f4, Tamron 90 2.8 and Canon 16 to 35 f4. My goal is to shoot the sharpest photos possible - both in studio (products) and environmental portraits. Money is a secondary issue. Here are my questions:
1. What's the best place to send the lens to "check it out" and repair if it needs it?
2. Since I know this isn't the "sharpest" lens, is it worth repairing? Or is there somewhere I can trade it in towards a new lens?
3. What do I replace it with? Do I go for the Canon 24 to 70 ll which does not have IS? (I tend to shoot environmental portraits without a tripod.) Or do I get a good 50mm and use my 16 to 35 and 70 to 200 to round out the range? Are there other lenses to consider - again with the goal of having super sharp images.
4. I hate to ask this - or do I just sell it all and get a Sony Riii? Maybe keep the 5D3 as my backup camera? I'm considering adding a Canon 100 to 400 this summer.
Thanks...
Good point. So should you set your AF a little beyond where you want to focus? I had a portrait photographer tell me to focus on a cheek vs, a nose, since that is 1/3 of the way across a person's head.
I have a Canon 5D3 with a number of different lenses. I bought an inexpensive ($10) focusing card from Amazon, but don't feel like I really have it dialed in. Then I tried a ruler set to a 45 degree angle. After some of my adjustment attempts, the autofocus was worse.
Can anyone recommend a good tool and technique for determining where to set the micro-adjust? (I know how to set the adjustments in the camera.)
Thanks
I've stated using Photo Mechanic to alleviate my high file size issue. I can get rid of the bad photos before loading into Lightroom - which saves a bunch of time.
I will typically throw out 70% of what I shot anyway due to duplicates (worse looking shot of the same thing), out of focus, etc.
