Newbei bought a 35mm without VR

[RichardsTPF]

Yes. It's 18-200mm VRII. And all shoots used timer. I was search mirror lock up for D90, and found exposure delay in my manual. Are they same function?

Nikon D90 Blog - D90 Everything!: Nikon D90 Mirror Lock -Up?

What: Mirror lock-up (often abbreviated to MLU) is a feature employed in many Single Lens Reflex (SLR) cameras. It allows the operator to reduce vibration-induced motion blur during exposure. From Wikipedia, the free encyclopedia

Does the Nikon D90 have it? Unfortunately no but it does have a pretty darn good alternative. This is called Exposure Delay Mode, Page 183 of your manual. It's says, "In situations where the slightest camera movement can blur pictures, Exposure Delay Mode On can be selected to delay shutter release until about 1 second after the shutter release button is pressed and the mirror is raised".


Honestly, there shouldn't really be any shake on a tripod with a timer.



1. This picture was taken on a tripod with my 50mm f/1.4 - does not have VR

2. This was taken handheld

This biggest difference between my pictures and yours is the shutter speed. I really think that if you were using a faster shutter speed you would have better results. Just my opinion.

 

[MTVision]

Did you use aperture priority for all the pictures? The aperture probably isn't affecting shake/blur whereas shutter speed might be. If you don't feel comfortable using manual mode then try S mode. Set your shutter speed a little higher then you've been using - the camera will determine aperture

Those bar code pics are cropped at 200% zoom in. The blur was caused by the camera shaking. Even though a tripod has been used, the minor shaking still exists. The longer shutter time extends its negative effect. If I shoot at less than 1/60s, the image will be a lot sharper. A high quality tripod might works much better than my $60 one. And I read some tread about hanging extra weight on the tripod to provide more stability.
Therefore, to get sharp image with non-VR len, I need to increase the iso if there is no sufficient light available.
And one of the most important solutions is practicing my handheld skill.

years ago a test was made using the same image, three images, one hand held, one on a tripod and one on a tripod with mirror lockup all at 1/500. Each image got sharper; with the last (tripod, mirror lockup) being the sharpest.

The differences were not huge but could be seen with the naked eye.

I have followed this thread with interest & decided to try to duplicate the OPs original shots. However my 35mm is a slower lens so I opted for a 50mm f1.7 to experiment with. I shot two frames hand held from about 4' & then severely cropped the images to include the bar codes.


ISO 200, 1/15s, f1.7

ISO 100, 1/100s, f 1.7

With the faster shutter speed we achieved better resolution although not sharp due to shooting with the lens wide open. Most lenses will improve sharpness considerably if stopped down 2 stops.

What I do not understand is the poor image quality the OP is getting with a tripod mounted camera.

 

[RichardsTPF]

Once I get home, I will try place my camera on the table and shoot under day light. What is size of your bar code?

The lower one is 1.5" across.

I shot @ 4' with a 50mm so you could shoot @ 3' with your 35mm to get somewhat the same image.

My 35mm 1.4 has it's very own camera it lives on. That lens is my bestie bestie friend ever. You shouldn't be having problems with the lens. If you are having problems, it's most likely because you have your settings wrong. Change the settings and you will LOVE this lens!
Pinkie Swear!

The below were all taken with the 35 mm 1.4 at varied apps, lighting, and sofort, but I shoot manual. It's honestly the best lens that I have, and I have most lenses. I have lots more photos than these, but this will give you an idea of how cool this lens can be under the proper settings. Practice and have fun!

I have no problem to shoot bar code from 3ft away. But at 6ft, the image become blur.
While the camera mount on the tripod 6' away from the box, looking at the barcode in the view finder, shaking my camera (no tripod leg movement), I can see the bar code circle around inside the center focus point. Do you think this little bit space/range of shaking could cause the blur?
Here are couple more pics shot at SP mode on the tripod. #1,2 are 3ft away from the subject, and #3,4 are 6ft away from subject.

Maybe it is the distance that is causing the lack of clarity. It's only 35mm so maybe the further away you are the less focus. If you can shoot clearly at 3ft w/no shake it should be the same at 6ft. The 5omm is equivalent to the way the human eye sees so I would assume that the 35mm would be a little less than that.

I'll try taking a picture of a barcode 6th away at 35mm and see how it comes out!

This was 6ft away handheld. It was actually 34.5mm f/10 1/200 ISO 400
The exposure is not correct in this picture. I shot this picture with the settings from the last picture I took

This one was shot at 6ft away as well at the same focal length as the one above. Handheld. 1/8 f/5 ISO 640. This one is blurry because its handheld and the shutter speed is slow.

Not sure if this helps at all. I don't really understand whats going on. There shouldn't be barely any shake if you use a timer on a tripod. Prime lenses are super fast as well. I wasn't using a prime for these photos as I only have the 50mm prime. If I were you I would read your manual and start playing around with the manual mode.

 

[RichardsTPF]

Do you think it's my len's problem?

 

[MTVision]

No. I think it is a DOF issue. I don't think you are used to such a shallow depth of field. Your other lens probably doesn't go below 3.5 or similar. I'm a noob so I can't really explain DOF that well except to say that if you choose a higher aperture then at 6 feet it will probably come in sharper. I sent you another private message as well. Let me know

Check out this thread. It pretty much explains what is going on with yours.
