A new set of pics using EZ and a 1.4 teleconverter




To see a larger version , click on each pic.....

Firstly , the location... The pink flower is about 10 feet (3 mtrs) from the camera. and the object behind it is about 3 feet (1 mtr)...

There is no "scientific" or "technical" expertise involved in taking these pics.... just a random thought that came into my head....

The first two pics are taken with the Sigma 1.4 X teleconverter lens screwed onto my FZ28 movable zoom lens. The camera has had the MPX count reduced from 10  to 7 mpx. to give the EZ (Extra Zoom) feature, this makes the 18X zoom into 21.4 X BEFORE bringing into account the Digital Zoom..... NO digital Zoom is used in these shots. So, with the Zoom set at 21.4 X and the 1.4 Teleconverter lens added, this brings the Optical Zoom up to almost 30 X...(29.96 ).... ALL the pics are taken "hand held" standing up....

The third pic has the camera mpx reduced to 3mpx.... giving MORE EZ...!... Zooming out to the "normal" 18X zoom position (before you go into digital zoom) and adding on the EZ, brings the ZOOOOM out to 32.1 X optical zoom.... (NO teleconverter used on this shot)...

The Fourth pic is a crop of the third one.... Cropped by about half the total of the orginal pic, to illustrate that having 3mpx as the EZ setting does not necessarily mean a huge degradation in picture quality  when cropped.... (It does show some serious degradation if cropped really close, i.e. to show the hover fly at the left of the flower head)...







The next two pics are a repeat of the previous two, as a double check on picture quality....

The last four are similar operations, except that I have added the 1.4 X Teleconverter lens to the camera, now giving a fantastic 45 X optical ZOOOOOM  (32.1 x 1.4 = 44.94 X optical zoom)

Check out the two "crop pics" to see the quality of the pics.... (don`t forget to click on the pics to see a larger version.)

Good enough for viewing on a computer screen, at 3mpx, maybe a little rough if printed out above the normal "postcard size".... but hey!.... Photography is supposed to be fun ! ! ! ..
