High Resolution 8.5x11" Chrome SD Professional Lens Test Chart, 3-Pack

I picked this up to check out my scanner. It worked well, but clearly shows that the chart is limited to 800 dpi at a 1:1 scan. I like that the supplier did not try to overstate the resolution.I've attached a small scan of an 800dpi horizontal gauge, and you can see the individual dots in the silkscreen pattern. The vertical 800dpi lines are more closely spaced (the size difference is because of my crop - look at the line / space ratio). You can see that the lines are a little different on the printed chart.On my scanner, you can clearly see. the silkscreen dot and shading patterns. However, as the chart is intended for reduction to a 35mm format, film resolution is going to be 4 - 5x the printed version.Also, the color and shading graduations look good. Overall, for the price, it is a great test target for color, shading and resolution.That said, I could easily see some unethical seller try to reproduce it on inkjet, so this is one of the products where you need to make sure you are getting the genuine article.

Well conceived and made. Sturdy and easy to use. The figures and printings are uniformly excellent. A highly useful tool which I can recommend unconditionally. The price is reasonable too. My only reservation is that, in my humble opinion, the product is a bit small and would serve more effectively if it were larger.YES I WOULD RECOMMEND this product to friends and family members.

Sensational, but not professional

Good chart to test cameras and lenses

Mixed emotions about these. I purchased so I can back focus my ENG camera. It seems to that job, but color balance may be slightly off, which is why I would not trust for that purpose. Expected to be printed on a plastic card or at least treated paper. Regular card stock quality which means if it gets wet or creased their garbage. For this reason they may include 3 which is good. Would have scored higher if product was better made and had good color fidelity. I bought for focus adjusting and it seems to do the job.

you may need this for lens testing.

It is colored version of 60s standard resolution chart that can be downloaded from web for free. I printed a better resolution copy on my home printer. I was trying to compare optical quality of a few telephoto lenses, 200 to 600 mm, in my basement with the chart filling half of the camera frame. It's pretty useless for such task since all of them, even cheap one, resolve the chart down to printing imperfection when different colors don't align perfectly and diagonal lines are not smooth. Maybe it can be used for wide lenses or on football field but it is cheaper to print it yourself and mount on cardboard.

Very pleased with the purchase. Would like instructions, but received great answers when I requested user inputs on Amazon. I set up the three cards in my basement arranging them in a diagonal to get a 33 x 24.75" test, which is exactly the 4:3 aspect ratio of my sensor. This is more demanding than simply taking an image of a single card and works very well for wide angle lenses. I use the test set up to find the sweet spot of my new and legacy manual focus lenses. By changing the ISO and the aperture, I can also see where performance drops off, compare lenses and cameras, examine depth-of-field, check AF accuracy (and my manual focus ability), color balance, etc. I compare results with known combinations of newer lenses and cameras tested by www.dxomark.com and get a feel for the how combinations (such as my legacy lenses) not tested by dxomark stack up against my cameras and lenses that are in the extensive dxomark database.
