Test of Nikon D800e, a DX lens and a Teleconverter

I was fortunate to finally get a Nikon D800e (36 Mpx) after a brief 3 month wait. I didn't, and I also think its the same with Nikon, expect that there would be such a huge demand for this camera. I don't know why Nikon seemed to leap so far ahead with its next generation but I'm grateful. I think there are millions (well a whole bunch anyway) more who also think the same.

This is a full frame camera and a DX lens will work but is cropped due to limited image area. The camera even has mode where it will auto detect a DX lens and crop accordingly. Knowing that there is still a little more image available with the DX crop I decided not to crop and use whatever was available.

Nikon D800e with 70-200mm f2.8 VR. The image on right is actual size of window pane

My favorite DX lens is the 18-200mm f3.5 VR and as I travel around I notice others who like this lens. While it may have some pincushion and barrel distortion, thanks to Photoshop lens correction, this is almost all eliminated.
Nikon D800e with 70-200mm f2.8 VR set to 1.2 crop. The image on right is actual size of window pane. I didn't realize at first that the crop factor also applied to FX lens.

It was while I was performing a resolution test with my D300 and the new D800e by using both the 18-200mm f3.5 VR and the 70-200mm f2.8 VR that I noticed that when full zoomed on the DX lens that vignetting seemed to disappear, but looked like a dime at 18mm.

This excited me more than the current test and therefore I decided to pursue this further.

The 18-200mm is really like a 24-300mm on a DX camera due to the 1.5 crop factor and this range will meet about 90% of my needs. With a 1.4 teleconverter on the FX camera it's now almost the same range as on a DX camera.


The test I performed was hand-held as I didn't need with this test to check for perfect resolution. I stood in front of a large apartment building in the parking lot across the street and remained at the same position while I changed the lens focal length.

In the 1st test, see film strip below, there is significant vignetting in the 18mm and slowly reduces as the focal length is increased. Even at 200mm there is still slight vignetting at the corners.
When the teleconverter was added then magic seemed to appear. At 18mm there is only slight vignetting at the corners and disappears by 24mm. The film strip below shows the changes with teleconverter added.

Now a favorite lens becomes useful on my full frame camera.

Most lens that have such a wide range of focal lens is all about compromises when being designed and built. The same with the 18-200mm f3.5 VR. Photoshop easily handles the barrel distortion. But this lens at the glass edge, maybe more is being used now, also has a fair amount of chromatic appellation. This is also handled well with Photoshop. Since most artistic images don't need to be sharp or well defined at the corners of a photograph then any additional distortion caused by using more lens area is not really a problem with digital-editing.

So when and if you do decide to go full frame one day then your DX glass can be useful with a teleconverter.

The reason this works is because the lens is now further from the sensor and therefore increases in size on sensor chip. Take a magnifying glass and hold it to show an image appearing upside down on a piece of paper. Now move the magnifying glass further away and watch how the image on the paper grows larger. The same happens with a teleconverter attached.

Any Fans of the Photographic Artwork of Niels Henriksen


That is certainty a self serving title and its fraught with many definitions of term 'fans' but it is also a chance for me to understand something about my readership.
This blog is just a few members shy of 1200 subscribers. I'm very grateful that so many find the photographs and articles enjoyable. There are also those who arrive by way of search engines, but from this total group I wonder how many committed fans of my photography I have.


Taken in San Miguel de Allende

I take many photographs, photo-edit them and then display these on the web just like millions of others do. But as a photographer the biggest pleasure is actually seeing the photo printed on photographic paper and how the texture and tone of the paper support the artistic vision.
But out of the entire collection of photographs I capture per year, only about 5 -10 actually have that extra quality or uniqueness that compels me to print large, frame and mount on a wall for display.

These fine-art photographs, as I describe them, go through a process of printing them on heavy mate papers (approx 300gsm). Depending on the detail and tonal qualities of the photograph I will print smaller versions (8”x10') on a series from 4-8 different papers to determine which paper best suits the image. After several weeks of just looking at them in different light settings I will select a paper for the final version.






In this image I combined 2 photographs to make the composite above as I wanted the boy to appear that he was searching for his princess.


Each of these fine-art prints are printed in a small edition series, currently 5, and then titled, numbered and signed and then made available for sale either through my Art web site ' Niels Henriksen Artworks' and through galleries.

As part of my marketing strategy, periodically (approx 18months), I increase my prices to reflect the larger, albeit still small, demand for my photographic prints.

Prior to this increase in November, I am offering to readers of 'My Camera World' a 25% discount on the current price for a period of 7 days after print is posted on this blog.

Guarantee
All prints purchased from me come with an unconditional full refund guarantee.  If you don't like it for any reason you get a full refund.
This makes purchasing a print from me completely risk free.
Each print comes with with a Certificate of Provenance. See example below






Over the next 2 weeks I will post an article about each of these prints that articulate my vision and story behind the photographs.

I hope that some of you will see a photograph that you enjoy and will sequentially purchase.  I think it's  important as a photographer and artist that we also collect other artists work and if not mine then someones else's. I am starting to have a decent collection of artworks already and will continue to collect new pieces every year.

By collecting several pieces I can then rotate them on the walls in my house and experience the same joy as when they were first hung.

Fine Art Print – 'Dancing Flames'

As with the previous print, this is also one of those lovely peonies flowers but from a closer view.

For this image, which I kept B&W, I wanted the soft petals to appear to be like dancing flames in a fire.


The image is low contrast and there is not a lot of fine detail. Therefore I wanted the paper to add tones in the soft areas. This paper, which I can no longer get, is very close to the water paper I use for my paintings
