1000 photos ruined
Apr 27, 2011

Welcome

Please tell me I have used the wrong technique with my Nikon 70-200 VR1 and Kenko 1.4Tc as all the photos from a recent event cannot be sold due to blurriness.

I have used the combination with that switch that specifies whether or not you want the first 2.5 metres taken into account switched towards the camera meaning to focus beyond 2.5 metres.

All the photos have what I call fractured backgrounds and very unsharp subjects.

I am hoping it is that switch that has caused it by being in the wrong position,if it was in the right position then I need to throw it out and get something better to do the job.There was no issue with VR as it was off all the time and I was shooting
in sunlight with high shutter speeds.

I tested the combination before using it and there wasnt an issue however
you could say I tested it on landscape scenes and not where a subject was from 5
to 50 metres.

Thanks and Regards
Roger

The focus-limiter is very unlikely to have anything to do with blurriness, unless you are shooting inside the focus-range of the limiter obviously.

Other than that the kenko is pretty soft in itself, and shooting wide open is really bad.
Stopping down is vital to get decent sharpness from this TC.

I ahve used the 70-200 VR1 with a 1.4x TC and have found it to be very sharp wide open at f/4. With the Kenko 2x, there is some softness, but that disappears stopping down one stop.

If you have blurry images, I would check the AF mode and how you were using it. Also, did you engage the VR and allow it to "stablize" before you snapped the shutter? Did you have the VR set to normal or active? Were you on a monopod or tripod? What camera are you using? Are the subjects moving? What shutter speed were you at? It's tough to dianose the issue without more details and sample images.

However, I can guarantee that the 2.5m to infinity limiter on the 70-200 VR1 is not the issue -- I use that way all the time for sports and get sharp shots.

I don't use the Nikon TC14 on the VR1 for lack of sharpness at 200 mm for just about anything below f5.6. If you were in a focus priority mode, the shutter would not release if the lens was not in focus - so the switch position has this failsafe.

This may seem silly and obvious, but check the other switch by the VR and VR limit that turns off the auto focus. This is easy enough to have happen by mistake.

Sample photo for review? Please also share your AF settings and focusing technique. Having used the Nikon 1.4X TC on an 80-200 AF-S wide open, I wasn't blown away by the sharpness (not even close) but was satisfied with the results especially on close distance subjects. The further away the subject, the more sharpness was lost (or there was a larger focus error).

Not my experience at all. My 70-200 VR1 is very sharp at all focal lengths wide open with the Nikon 1.4x TC. Only with the 2x TC do I have to stop down. Never had an issue with the shutter that you mention on any of the bodies and the 70-200, including D100, D200 and D300s.

It's not an issue, it's a feature. If the lens is not in focus in AF-S mode, the shutter will not release if the image is not in focus. It's that simple. So, if one were to try to focus on an object closer than the limit switch would allow, the shutter would not release as the focus sensor would not detect focus. If one is in AF-C mode and/or release priority, then the camera will take an image even if the image is not in focus. In that case, the limiter setting could be an issue.

I;'ve been told to never mix brands of teleconverters. I have a Nikon TC14 that I use on my 70-200 but I would never use it on my Sigma 150-500mm

Thanks all

As I have said,there wasnt any VR being used,samples may eventually follow.

I had entered a lens fine tune with this combination and I have now deleted it

and will see what results I get.

There is another factor too that might have been the issue,I have recently shifted back from AF-ON to Shutter release but have left the front setting on Continuous focus,maybe it should be back on Single focus.

I was also using the Ch setting,there was no difference between hand held and images on a monopod.

Thanks so far

Roger.

Can you post some samples? Really hard to troubleshoot an image if there's no sample to look at.

That's fine, since it won't mount. Nikon TCs (without grinding away a tab) will only mount on a few select lenses.

Kenko TCs are designed to work with the widest selection of lenses with out issues.
I use one on my 70-200vr, Tamron 90mm macro, etc

Focus priority makes a lot of sense...

If you have the focus switch on camera in "C" than it will take the picture without focus. This may be your problem. If you are good enough to be selling your work I'm surprised you don't understand the camera. There is a green dot in the view finder that will light up when you have achieved focus.

I understand the focus priority feature...use it myself sometimes. But I guess I didn't see how the limiter on the 70-200 could even interact with that feature if the subject was 5m+ away?

Yes, that is the simplest explanation -- he's using shutter release with AF-C...but doesn't understand how to use it effectively.

I'm also surprised that a pro would not understand the camea, as well as taking 1000 potential stock shots without inspecting to verify exposure, focus, etc.

Welcome

Ok,so Shutter release and AF-C supposedly arent compatible,that sounds a likely issue then, as I have said earlier I was an AF-On user and have had to back away from that and go back to Shutter release.I understood everything about Continuous focus and AF- ON but found focus to be unsatisfactory ,but saying that I didnt use it with Release, I always used it with Focus mode ,it never had any delay in focussing and would still take photos before focus was achieved on occassions,odd.

No I am not a PRO ,just a struggling DSLR user who has a lot of experience trying to get this camera to do its best,I sell a lot of photos that I manage to get close to a pro standard for most of the time.

My next test will be using Release mode and going back to AF-On and have the Lens Fine tune deleted.

Yes ,you are anxious to see the problem photos,they are on another computer and I will try to get them here eventually.

Thanks again for the help.
Regards
Roger.
