Forgot about minimum focus distance.

Today I was taking some product photos of my wife's wood turning project. Normally I use either the DA35 Macro or FA 50mm F2.8* macro for this, and on tripod of course. I also use electronic shutter & live view with remote shutter release. Well after finishing using the FA50 I decided to take a few with the DA *55mm F1.4 for comparison. The photos from the DA55 were all a little soft, which I didn't understand. This has been a really sharp lens for me, even at 1.4 and I am shooting at 3.5. I took the KP off the tripod and took some more photos hand held and they were sharp as expected. Put it back on the tripod and soft again. Then my brain kicked in and I realized I had not moved the tripod back after using the macro lenses. I was about 15" from the object, not the minimum 18" focusing distance. I moved it back to 20" and all was good.

Anyone else admit to having done this?

This happens to me with longer lenses. Sometimes I think there is a problem with either the lens or the camera. Then I take two steps back and they focus. Minimum thinking and minimum focusing distance

I suppose this happens a lot, best to always take a test shot.

Yep been there done that. Several times now, I have forgotten my camera is in manual focus mode and clicked away happily (they always look fine on the back LCD), until finally I zoomed into one and found they are all OOF!

Definitely happens whenever I use a long lens, not in small part because I rarely use anything longer than 100mm or so. I'm so used
to shooting wide or macro that a 2m+ minimum focal distance always throws me.

It's my biggest complaint about my 85/1.4, the 1m min focus. The 45cm min of my 50mm lenses gets in the way sometimes too. I guess a 50mm macro is something I should have on my wish list.

Yes, I get that sometimes as well, when I have set up a bird feeder outside only to find out when the birds arrive that the thing is too close for my M300/4.

My Takumar 35mm f/2.3 and Rokinon 85mm f/1.4 doesn't do close focusing. It gets in the way at times.

Another soft picture moment is when you roll in auto exposure mode and forget to keep an eye on the shutter speed. SR can only go so far, and it can't cure motion blur.

The worst doh moment is when you snap away at ISO 1600 in bright sunlight...

Yes I do this too often . For me a too slow shutter speed is the worst because I make more mistake before it is caught .

one of my problems is my fat thumb hitting the 4 way selector and settings being changed without my noticing the change
