    Question Tamron 18-400mm f/3.5-6.3 Di II VC HLD Lens Focus Issues

    Stepped up to the full frame world beginning of the year buying a D750 and a couple lenses. Really like macro work so snagged a Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED lens and really LOVE this lens. Great clear and crisp shots. Also bought a Tamron 18-400mm f/3.5-6.3 Di II VC HLD Lens for general use when not shooting macro. Haven't used the Tamron lens much but decided to start getting used to this. Have taken this out several times now and yesterday was a real eye opener. Bright Florida sunlight and nice steady subjects and thought I was snagging some great shots. When I got home I was extremely disappointed with how soft and often out of focus all the shots were. The Nikon 105 shots I can zoom in super close and have great clear focus, the Tamron didn't take a single shot that look crisp or sharp

    Have read about some of these Tamron lenses having focus issues but usually with hunting. Have also read about doing some tweaking to the focus points but feel with a brand new lens I shouldn't have to do that.

    Any suggestions or hints to get crisp shots with this lens?

    Thanks in advance for your help.

    First of all: welcome! Looking forward to seeing some of your bright, sunny Florida shots...during the winter when I'm buried under 36 feet of Jersey snow

    I don't have experience with that lens myself, but I've seen a fair number of other members talk about their Tamrons so hopefully one will be along shortly with their thoughts on this. Can I ask, have you tried shooting it in manual focus? And if so, are the results the same?

    Often 3rd party lenses need adjustment in camera. They may be front focusing, focusing in front of the subject. Or back focusing, focusing behind the subject. Read about how to make this determination and adjustment...

    Welcome, its not just third party lenses, sometimes Nikon lenses can need in body adjustment, as Chris said look it up and test.

    Welcome!

    I have that lens on my D7100. No problems. SOOC, no processing, only resized.



    Post a sample with the EXIF.

    Are you sure the VC is working properly? And you know that your shutter speed should be at least as fast as the focal length, right? For example, if you are shooting at 400mm, at a minimum your shutter speed should be 1/400" - preferably a little faster just to be sure.

    Please give us some examples of your focal length and shutter speed used.

    I'll try to get time to shoot some test shots and upload what I'm seeing. Not sure how to adjust the D750 for in body adjustments. If that is done will that be specific for that lens as my Nikon 105 is working extremely well and would not want to mess that up? How do you do the in body adjustments? (newbie talking here, sorry). And not at all sure about how to test if the VC is working properly. Thanks.

    There are several methods to tune the body to the lense. Look in to dot tune it is fairly easy. It is lens specific affecting only the one being adjusted and can be set back to the original settings if you don't like the results.
