Using the Olympus TCON 17 1.7x teleconverter with a Nikon 1

These three photos were taken with a Nikon 1 V2, the 1 Nikkor 30-110mm zoom, and an Olympus TCON-17 1.7x teleconverter. I am extremely pleased with the results using the teleconverter.

On the Nikon 1, I use a 55 to 52mm adapter ring, and then a 52mm to 40.5mm adapter ring to mount on the Nikon 1. (I could not find a 55 to 40.5 mm adapter).

I bought the TCON17, used, on Ebay, for $15. That is not the normal price – prices are usually closer to $80 to $110 U.S. I think the person who sold this one did not know what they had.

Olympus had made 4 teleconverter lenses that appear to be essentially identical – the B300, the unlabeled TCON17, the TCON-17, and the TCON-17x. I have what I believe is the “unlabeled” version. I understand the early models did not include the TCON-17 model # on the lens.

I also did tests on a micro four thirds camera using the TCON17 with the Olympus f/1.8 45mm lens – works great (makes a 150mm FF equivalent). I tried the Lumix 45-200mm, but the TCON17 made the images soft and with much chromatic aberration.



The shot below was to test for chromatic aberration, by having the high contrast areas of the branches against the gray background. DSC_3160

Not surprisingly, contrast is a little soft with the teleconverter, but that is easily corrected either in camera or using Lightroom.

I will post more photos in the future, but it is hard to get out taking photos right now as we live in a rainy climate.

VR needs compelling content to succeed

Consumer 3D faded due to:

  1. Lack of content, lack of content and lack of content
  2. It was launched in the midst of economic depression
  3. The 2011 quakes and tsunamis damaged manufacturing plants (as well as later floods in Thailand), after which manufacturers eliminated their consumer 3D camera products

VR faces a similar challenge of lack of content, plus VR gaming requires top of the line computing gear that few people own just yet.

Which leads to words of caution:

Early optimism that virtual reality is about to blossom into a new mainstream medium could collapse into despair

VR seems likely to achieve success in gaming and specialized applications (engineering, science, medicine for example).

Will VR be a big story telling medium?

How will consumers react to the need to wear VR helmets?

(I use the term “VR helmets” since they are …. Consumer tech reporters said 3D required wearing “3D goggles that no one wanted to wear” – the same writers now enthusiastically endorse VR helmets because … well, wearing a helmet is simpler than wearing glasses?)

Blogging and Youtube videos unlikely to earn much income

The author of the excellent Micro 4/3rds Photography Blog reveals the numbers behind his blog – and with blog ads, commissioned sales links and Youtube videos with ads, the combination earns very little money.

Most of the top video channels on Youtube got started very early back when it is alleged most channel creators gamed the system to increase viewership [1]. While some recent arrivals have achieved viewer success, it may take years to achieve a reasonable following, or money spent on promotion. It is said that even for the successful Youtube channels, the creators most creators must also sell ancillary products (notably music but also t-shirts, hats, etc).

So why blog or produce Youtube videos? For many of us, do these as a hobby. We enjoy sharing helpful information with others. For example, I publish a popular tutorial blog on programming in App Inventor (See App Inventor 2: Learn to Code!). Other reasons include emphasizing one’s credentials in the subject, to advertise one’s skills to potential clients, to be involved in a social web of people with similar interests, perhaps to sell related products and services, and more.

Footnote – The “old” way Youtubers Got Views

[1] Many Youtubers figured out the way to get viewed – and obtain subscribers – was to generate lots of fake views to jump up high on the “Most Viewed” lists. In the early years of Youtube, it was easy to do this: copy the video player embed code 100 times on an HTML page and just keep reloading the page!  (This “feature” was disabled long ago!)

Appearing on the “Most viewed” lists increased visibility and views rapidly. Others say that nearly all of today’s successful channels, which started in the 2005-2008 first three years of Youtube, got there by manipulating view counts.

In 2012 or 2013 Youtube seems to have made changes in the search system that caused viewership of minor channels to fall. Starting about 2 years ago, views of my own videos fell sharply – and I no longer post much on Youtube, having instead migrated to Flickr (Flickr supports videos too!) On Flickr I often get as many views in a day as I would see – ever – on Youtube 🙂
