It’s week 45, but I just took this “summer-looking” image! This picture was taken using a Helios-44 lens. Helios is probably the most famous vintage lens there is; it was produced in the old Soviet Union in 1958-1992 (my copy is from 1982) and is one of most mass produced lenses in the world. It comes in several variants. The version I have (“M”) is supposedly the worst one, but I’m very pleased with it. It’s built in solid metal, focuses down to 0.5 m, and has a mag ratio of 1:6:5 at the closest focus point. I bought it cheap (FYI – the average price in October 2018 was only $32) including an M42 adapter to fit in on my Fuji.
In case you’re interested, there’s a weekly podcast called “The Classic Lenses Podcast” and there’s an entire episode dedicated to the Helios-44 here
New gear! 🙂 Test shots!
I got another vintage lens: Pentacon 135 2.8. It’s a telephoto lens made in GDR (East Germany), I found one in mint condition and got it super cheap.
There are two versions of this lens, and I got the second version which is inferior to the first as it only has 6 blades and the diaphragm can close to f/22 (the first version has 15 blades and can close to f/32), but still a very nice and sharp lens which is fun to use. The minimum focusing distance is 170 cm, something that will take a bit getting used to for me, especially since I’ve mainly shot with a 60 mm macro lens the past year. Anyway, today I went for a little walk and took some first test shots with my new (although it’s older than me) lens. It can of course only be used in full manual mode, but the focus ring is smooth and easy to use so it’s not really a problem I think.
This pretty little butterfly is called Small Copper (Lycaena phlaeas) in English, “Small Fire butterfly” in Dutch, and “Small Goldwing” in Swedish. I’m not sure, but I think (guess) one reason why it’s “gold” in one place and “copper” in another is because the colours of this butterfly varies slightly depending on where it lives.
I was lucky to find one sitting in the warm sunlight (usually they’re very active in bright sun) and was able to shoot it (I mean photograph) slightly backlit which really brought out its beautiful colours. Notice that the orange at the tip of the antennae also matches its wings, very stylish!
Update: Last week, WordPress didn’t recognize my weekly post as a post, thus it didn’t show up in the Reader of those who subscribe to my blog. Luckily, this issue seems to be resolved now!
Week 32! No exotic or unusual butterflies today, but happy to see them just the same 🙂 Have a nice week!
Update 8/13: According to WordPress, this blog post from yesterday doesn’t exist and this site was last updated 8 days ago. Therefore, this post doesn’t show up in the WordPress Reader either 😦 …. If you read this, thank you for visiting my blog.
Today I’ve been photographing dragonflies in Diemer Vijfhoek 🙂 I still don’t have a macro lens; these were taken with XF18-135 and all are cropped. Anyway, here are four beautiful dragonflies and some brief information about them. Hope you’ll like!
(1) Vagrant darter (Sympetrum vulgatum) – male
Quick fact: It hovers and then, as the name suggests, darts out to surprise its prey. Then they take their catch to a favoured perch to eat it. Very similar to the Common darter (Sympetrum striolatum), but it has a “hanging” mustache.
(2) Black-tailed skimmer (Orthetrum cancellatum) – male
Quick fact: It’s a narrow-bodied, medium-sized, straight-sided dragonfly. It can be seen flying low over the bare gravel and mud around flooded gravel pits and reservoirs, before landing on the bare shore to rest in the sun.
(3) Migrant hawker (Aeshna mixta) – male
Quick fact: It’s not a particularly aggressive species, and may be seen feeding in large groups. Hawkers are the largest and fastest flying dragonflies; they catch their prey mid-air and can hover or fly backwards, although the Migrant hawker is smaller than other hawkers.
(4) Black-tailed skimmer (Orthetrum cancellatum) – I’m not sure, it’s either an immature male or a female
Quick fact: They breed in very large number in newly flooded gravel pits. (See also above.)
Damselflies! Click to view slideshow:
Dragonflies and damselflies are closely related, both are part of the insect order Odonata. However, they are not the same! Odonata includes about 5,900 species of which about 3,000 are dragonflies (suborder Epiprocta, infraorder Anisoptera) and about 2,600 are damselflies (suborder Zygoptera).
Here are five differences to look for:
★ Size: Dragonflies are generally much larger. The most common dragonfly in The Netherlands (Ruddy darter) is 3.4-3.6 cm long and has a wingspan of 6 cm. The most common damselfly in The Netherlands (Blue-tailed damselfly) is 2.7-3.5 cm long and has a wingspan of 3.5 cm.
→ Fun fact: the largest extinct dragonfly had a wing span of 70-75 cm (roughly 30 inches)!
★ Eyes: Dragonflies have much larger eyes than damselflies, their eyes take up most of the head and they are wrapped around from the side to the front of the face which kind of makes it look like dragonflies are wearing snow goggles. Damselflies also have large eyes, but the eyes are clearly separated and appear on each side of the head. →See picture below!
★ Body shape: Dragonflies have bulkier, stocky bodies that appear shorter and thicker. Damselflies have long and slender bodies.
★ Wing shape: Both dragonflies and damselflies have two sets of wrings, but the shapes are different. Dragonflies have hind wings that broaden at the base, which makes them larger than the front wings. Damselflies have wings that are the same size and shape for both sets, and they taper down as they join the body, thus becoming quite narrow as they connect.
★ Position of the wings when resting: Dragonflies hold their wings out perpendicular to their bodies when resting, so they look like small airplanes. Damselflies fold their wings up and hold them together across the top of their backs, from a distance they kind of look like a very thin safety match.
Here’s a picture of a Map (Araschnia levana), the butterfly best known for having two forms: levana (spring brood) and prorsa (summer brood). levana individuals are primarily orange in colour, and prorsa individuals are mainly black with some white markings. This here is a summer brood showing off its beautiful underside (a map like pattern which look the same in both broods)-
Here’s a picture I took during my vacation in Sicily, a beautiful Violet carpenter bee (Xylocopa violacea)! This bee is huge, about 3 times the size of the biggest bumble bee we have here in Holland. Unfortunately I only had an old iPhone at hand, in real life its dark blue-purple colour was much nicer.
Week 26 = we’re half way through 2018 already!
Today I want to share some pictures of a Comma butterfly (Polygonia c-album), I’m not entirely sure but I think it’s a summer generation of sub-species (f.hutchinsoni).
In most languages this butterfly is called something with a reference to the white mark it has on its side, e.g. in English it’s Comma, in Spanish it’s C. Although in French it’s called Robert-le-Diable (“Robert the Devil”) because of its jagged wings. The scientific name also refers to the mark: “c” + “album” (which means white).
This butterfly has very good camouflage, both as a larva (mimicking bird droppings) and as an adult (mimicking a dead leaf).
PS. I’m off to Sicily so there won’t be any updates the next coming weeks!
Today I want to share FIVE FUN FACTS about dragonflies 🙂 A beautiful Common darter lady (Sympetrum striolatum) kindly agreed to demonstrate the facts in my pictures!
★ FACT 1: They were the first insects to inhabit this planet – 300 million years ago! In other words: they’ve had a looong time to perfect the art of flying and hunting.
★ FACT 2: They’re flat out terrifying if you’re a mosquito or other kind small bug, because they don’t simply chase down their prey but they snag them from the air with a calculated aerial ambush! Dragonflies can judge the speed and trajectory of a prey target, and they’re so skilled they have an impressive 95% success rate when hunting.
★ FACT3: They can fly in any direction, including sideways and backwards! (How cool is that!) Plus, they can hover in a single spot for a minute or more. But that’s not all. They’re also fast – some species reach almost 30 km/h (18 mph) – and one species (Globe skimmer) flies almost 18,000 km (11,000 miles) during migration which is the world’s longest insect migration. (Compare this with the famous Monarch butterfly migration of 2,500 miles.)
★ FACT 4: Both dragonflies and damselflies are in the order Odonata, which means “the toothed ones”. When hunting, they can catch the prey with their feet, tear off its wings with their sharp jaws (so the prey can’t escape) and scarf it down – all without needing to land. In short: Their ability to rip apart their prey takes their predatory prowess to another level.
Update: It should be noted that dragonflies don’t bite humans and they don’t have any stinger! i.e. they cause no harm to humans. (Thanks for pointing this out, Greta)
★ They have nearly 360 degrees vision! The enormous compound eyes contain 30,000 facets and they can see the world in colors we can’t even imagine. (In depth read here)
Update: It’s also worth mentioning that dragonflies have a significant, positive ecological impact. In its nymph stage, they eat harmful aquatic organisms and thus help keep our waters clean. The nymph can contribute to the ecosystem for up to five years before becoming a mature adult! As adults, they mainly help humans by eating mosquitoes and other insects that spread diseases such as malaria, yellow fever, anthrax, etc.
Some random pictures I’ve taken with the Pentacon 50 mm lens… Have a nice week everyone!
