Problems with my Tamron 90mm Macro

I was testing my Tammy indoors, both in well lit daylight conditions and later in the evening with tungsten, with no significant difference in performance.

I do like my Tammy, it is a superb lens and will definitely send it in for a check-up and repair. Since it is no longer under warranty, I hope that it really is just a minor fault. :)

The camera is not haunting for focus, it's trying to find focus ( going back and forth a few centimetres around the focusing plane ), but just can't make a lock on focus.

In LiveView it is haunting for focus, misses focus completely but makes a lock. :mad:

As I said before it sometimes makes perfectly good AF lock - both in LiveView and when I'm not using LiveView. :hmm:

Well could be, that Pentax is trying to tell us that we need to buy their new WR macro. :D

In LiveView AF still works very erratic. Now the camera almost always locks focus, but it isn't focusing correctly. It's just frustrating to listen to the AF motor as it is kicking around lens' focusing mechanism, like it has no clue where to lock focus. I tried the FA 50 and LiveView works OK with it.
With Tamron it's making random back and front focused shots. And it's not missing focus by just a few centimetres it's missing focus by 20, 30cm or more.

When I shake the lens it's making a sound like there is some screw or something loose in it. :o Could be that this is messing with focus? The lens works fine with K10D though. DAMN IT!

Hi,

Has anyone been using Tamron 90mm Macro on K-5 and found that it has problems finding focus? I was just checking today all my lenses on K-5 to see, if any of them need AF adjustment, just to find that K-5 realy doesn't like my macro lens. :(
The focusing is just erratic. :mad: So I thought the focusing would be OK as long as I wasn't trying to focus on objects that are difficult to lock onto ( low contrast objects, objects in the back/foreground ). In almost every case the camera is just focusing back and forth several times and stopping without locking focus on anything. Tried to focus on some simple to focus objects, but K-5 just refuses to find focus. Trying again and again, but focus only locked on the object a couple of times.

So I tried this lens on my old K10D and focusing works much better, not locking focus only a couple of times. And even if it didn't find focus after the first try it locked focus after I pressed the af/shutter button again.

Is it possible that K-5 has problems with this lens, or is the lens?

That's because color space is set to AdobeRGB. If you change it to sRGB files will be named IMGPxxxx.

I own this lens and here is the shot that was made at 17mm and f2.8 and a crop. Shot in RAW, no PP except for the CA correction. Anyway I really like this lens.

Yes, the sharpness is simply amazing.

This is cropped at 100%. No PP except for a little exposure adjustment.

I shot this with my Sigma 17-70mm @17mm and f2.8

The original photo - almost no PP.


And this is after PP.


I like the second one better, since B&W makes it look more like 3D. What do you think?

I have had mine for almost a year now, and I never had any regrets buying it. It is a very good lens, well built, sharp, versatile and with decent macro capabilities. So unless you are looking for a zoom with fixed aperture this lens won't disappoint you.

The colors are really not that great this time of year. But they will be in the summer, which means that I will be going there at least one more time this year. :lol:

@LaRee: I shoot in RAW and when converting to B&W I always use the saturation control in ACR, as for this last shot. For the second shot I did the same and I increased the saturation for the greens and the blues.

Took my car for a spin a couple of weeks ago and here are the results:

Railway bridge

shot #1

Pentax FA50 @ f3.5 , 1/1250s, ISO 100

shot #2

Sigma 17-70 @ 17mm, f3.5 , 1/320s, ISO 100

View to the Alps

Sigma 17-70 @ 17mm, f8, 1/200s, ISO 320

The second one is my favourite and I must say that I realy looooove my Sigma 17-70. This lens is worth every penny. :lol:
