Lens not sharp?

As I've mentioned before, I write a blog, and take a lot of photos for that blog. Some of that involves food photography. Lately, my Tamron 17-55 seems to have issues with not being as sharp as it once was. At times, even though it is on Auto Focus, it doesn't do anything.

Could it be a connection issue? There are times when turning the camera off and on fixes it, but other times I have to take the lens off and put it on again.

I'm thinking I'll need to go to my 50mm for the food photos from here on out. I prefer not to use a tripod in the kitchen, so everything for me is handheld, which I know compounds any lens issues.

Do I need to be cleaning connections, or what should I look at doing to help this lens?

Other lenses seem to work just fine. This lens would not auto focus at times on my other camera body as well. I'll try cleaning the contacts on it.

Mike - It doesn't matter how far away from a subject I am. I'll take a few test shots this weekend with that lens and another, keeping them both on a tripod at the same distance, and see what happens.

I tried side by side shots between the Tamron and my Canon 50mm. Today, the Tamron was working fine.

I used a tripod, had the distance at 31 inches from focal point, and used the 2 second timer to prevent camera shake. All settings & lighting were the same. I switched lenses after taking a few shots in a row. There was very little difference in quality between the two. It frustrates me that the focus issues are inconsistent.

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      Problems with Yetti

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
