Sigma 105mm f/2.8 Macro Lens

Sigma 105mm EX DG Macro lens.I pulled out my old Sigma 105mm macro lens from my treasure chest — the only prime lens that I have at the moment — to remember what this lens is all about. Sadly it rarely gets any use. I don’t do any macro photography and this thing is capable of 1:1 reproduction.

UV filter degrades the quality.At first I tried taking a coupe of portrait shots and it really is not usable inside. 105mm is just too long. However a bigger problem was a lack of contrast or a visible haze. I didn’t figure it out until later, but the culprit turned out to be the UV filter on the lens. Moral of the story? Don’t put cheap glass on top of a lens — either buy the ones that are too expensive to make sense or don’t buy any at all.

Nikkor 24-70mm f/2.8 lens.Overall the shots come out pretty sharp and the manual focus for macro shots works well as well. In the test shots that I took bokeh did look pleasant. Auto-focus itself is rather slow.

100% crop of 1:1 macro shot of 50mm marker. You can see it on the actual lens on the shot above.I should try to take it out more and try taking a couple of portraits shots outside. Maybe I’ll start using it more often.

Old Lenses, New Camera

Macro lens shot. Much easier to work with less focal length and much faster AF.I did a couple of experiments with old lenses on the new FX sensor. First of all most of them has gotten into a much “apartment” friendlier range. 50mm acts as one, not as 75mm on DX. So is 105mm macro. I’ve noticed it focusing much faster on the new camera as well.

As wide as it gets. 10mm on 35mm sensor.Wide angle though is really something. It really is a DX only lens, hence the black circle. However 10mm on FX sensor is weirdly impressive. Talk about wide.

The mega cat.All the distortion also creates interesting effects. Here is a mega-cat for you. The camera actually has a DX mode which produces close to 6 mega-pixel images, same as D70 did. Or you can crop the circle out manually, which I prefer to do.

"Meow. Let me sniff that lens."And this one is a great shot. Too bad it’s not sharp. Shublik got extremely close to the camera to “distort” so much, but since it’s not a macro lens it doesn’t focus at such close distances.

Shublik The Model

I really like the amber color of the eye. Although his eyes are not nearly as amber as his father's.I managed to take a few photos of Shublik’s eyes today. Normally it’s a hard task since he just does NOT sit still for a second, and today wasn’t any different.

This one is funny. He was playing with his "mouse", lost it, and switched to his paw.My trick was to use a lens with a focal length of 105mm at f/2.8 and a flash. This way I could stand far away and the amount of light allowed me to freeze his movement — very short exposures. The macro lens has performed well, I think.

"Mouse" hunt.I still had to discard most of the photos, but these 3 are the best of the series. Hope you like them too, as I’ve become very biased with things related to this little monster. teeth

Lightbox

Bulova watch photographed inside the lightbox.With all the watch excitement lately I needed to come up with a good way to share with the readers of the blog. For that you obviously need good pictures. And to take good pictures of watches you obviously need a lightbox of some kind.

Lightbox in use. Desk lamps from the left and the top, remotely controlled Nikon SB-800 flash from the right. I used a simple guide posted on Strobist to build one without spending a lot of money. Borrowed a cardboard box from work, Alena bought some tracing paper and that’s pretty much it.

Construction process is very simple. Just cut out 3 of the sides and tape over the cuts with tracing paper.I need to replace one of the lamps with a regular bulb with a lamp with a tungsten bulb to get rid of the yellow light. And I guess a 2nd flash would do wonders too. But overall not bad of a result at all for a first try with this cheap structure.

Macro Portraits

Macro Self-portraitsI started to get nostalgic about taking macro pictures, and since I didn’t have any good subjects I decided to look through my archives of raw images. I found a good picture, did some post processing and ended up liking the result.

Later on I noticed macro-selfs reflecting in the drops.

Colorful Insects

ButterflyThe main reason I wanted to go to Canada was so that Alena could see all the great things that I’ve seen. So we were making stops at locations which I’ve visited before many times.

This time around we decided to stop by the botanical garden. I’ve seen signs pointing to it many times, but never actually went there. The garden itself seems to be rather large, and we were short on time, so we visited only one part of it: Butterfly Conservatory.

Butterfly Refuses to Fly AwayI armed myself with my new macro lens and went hunting. The first butterfly that we came upon was actually flying outside of conservatory, and the pictures of it came out the best. The conservatory itself was filled with all kinds of beautiful and exotic butterflies. They would even land on people and would refuse to fly away.

BeeBut I guess because the lighting condition weren’t great and I’m only an amateur majority of the pictures came out fuzzy. It still was a very fun experience nevertheless.

BumblebeeThen on our way back I stumbled upon a nice bumblebee flying around the flowers. He didn’t really want to strike a pose for me, but I think I still got a nice shot. Looks like he was flying around and collecting nectar from flowers.

My dad took a lot of butterfly pictures as well on his camera. Looks like he and my mom were having fun too. Also we got yet another magnet for our refrigerator. Alena refuses to leave without those from anywhere now. ) We brought 3 new ones from Canada.

Lens Galore

Shot of Nikon Kit Lens taken with Sigma Macro Lens.I just love getting presents! This birthday has been especially good for my photography hobby. I got 2 great new lenses. One is a wide lens that I mentioned yesterday was given to my by Alena, my parents and my sister Lina. Today I got another one. An awesome Sigma macro lens (check out the shot on top) from Eldar and Moisha! Last year was great as well, when I got a super zoom lens from Maruks for my birthday. Thank you, everybody!!!

Here’s my current list of lenses (all autofocus), listed in the order I got them:
  • Nikon Zoom Super Wide Angle AF 18-70mm f/3.5-4.5G ED-IF AF-S DX Zoom-Nikkor
  • Sigma Zoom Telephoto 70-200mm f/2.8 EX DG APO HSM
  • Sigma 2x EX DG APO Autofocus Teleconverter
  • Nikon Normal AF Nikkor 50mm f/1.8D
  • Sigma Zoom Super Wide Angle 10-20mm f/4-5.6D EX DC HSM
  • Sigma Telephoto 105mm f/2.8 EX DG Macro

I can’t wait to take more pictures with my new ones now. Niagara Falls will be a good test for wide angle lens, weather permitting.
