Birds of the Philippines


Philippine Bulbul (Hypsipetes philippinus) by alabang, on Flickr

The Philippine Bulbul (Hypsipetes philippinus) is a songbird species in the bulbul family (Pycnonotidae). It is often placed in the genus Ixos, but is better retained in Hypsipetes as long as this is not entirely merged into Ixos, as it is quite closely related to the type species of Hypsipetes, the Black Bulbul (H. leucocephalus).[1]

It is endemic to the Philippines. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests; on Mount Kitanglad on Mindanao for example it is abundant in any kind of primary forest at least between 500 and 2,250 m ASL.[2]

Fledglings of the Philippine Bulbul were recorded on Mindanao in late April, but the breeding season seems to be prolonged as females with ripe ovarian follicles were still found in April and May. Territorial songs are heard at lower altitudes as late as May, while further upslope the birds are silent at that time of year and presumably engaged in breeding activity. The Besra (Accipiter virgatus) has been recorded as a predator of young Philippine Bulbuls, and this or other goshawks might also catch adult birds.[3]

A common and adaptable bird as long as sufficient forest remains, it is not considered a threatened species by the IUCN.[4]

Speedring for alien bees help.

agierke said:
buy the speedring that PCB sells on their website. the connection to modifiers is typically universal (some rare instances where a modifier wont fit that well) so you have to buy the speedring that will mount to whatever light you are using.

So which one should I get with the AB1600? Seems like these are for the retired units?

400 2.8

I don't shoot wildlife. But this spring I'm shooting track & field and golf. I am taking my 400 f/2.8L IS I tomorrow and Monday for the golf tournament (one camera A) and a 70-200 f/2.8L IS II on camera B. I did a track meet today and while the 300 f/2.8L IS I was great, there were times when I reallly could have used the 400. For instance, sun was going overhead, and from closest to farthest away from me, you had 1. pole vault, 2. javelin (center of track), and 3. long jump (other side of infield). I could have easily gotten pole vault with the zoom and both javelin and long jump with the 400, but alas, I had the 300 and long jump was iffy so I moved.

How large effect is the focus breathing on primes vs zooms? I have heard it can be a problem with macro photography and focus stacking.

I tend to have more issues with wind/subject motion than focus breathing/macro rail displacement. When focus stacking in PS, you can have the software try to align the source photos to each other before blending them together. The software also scales the photos appropriately.

New patents for Canon fast primes

RGF said:
Patents do not guarnatee production. Sometimes they are done to hold IP.

Shure, but these patents show typical lens designs which penetrate the market since a few years: Standard lenses with a negative front element. This is well known from wide angle lenses for (D)SLRs which use retrofocus designs to give enough space between last lens and image plane.

If I read the patent correctly Canon has decided to use a retrofocus design instead of a double gaussian design to avoid problems with longitudinal CAs: The retrofocus design gives more variability to introduce more lenses/alternative lens geometries to adress longitudinal CA correction without compromising other parameters.

Longitudinal CAs are the main problem with high aperture lenses which aren't easily removed during post processing - I am shure that these patents have a good chance to flow into real products!

Just my 2ct - Best, Michael

Which is also what Zeiss announced a while back, with their 50mm f/1.4 Distagon (Distagon is their retrofocus, normally found in 21-35mm, or 40-65mm on Medium Format).
Either canon's going down the same path, or they're at least going to patent some to block zeiss.

Sub £100 Nikon Lens for Airshows

Haydn1971 said:
So potentially the older faster primes are going to be a non starter - any thoughts on the cheapo 55-200 ?

The old non VR 55-200 has reasonable resolution for the price, its a bit cheaply constructed, so don't batter it around.

Its going to be a struggle as far as AF and shutter speed, a slow aperture and limited ability to use high ISO settings before noise becomes a problem.
It sounds like the best compromise for your buck, a manual focus lens might be pretty frustrating for flying aircraft, but for those on the ground, it should be easy. Just make sure he keeps his shutter speed to 1/250 or more when zoomed out.
A rental of a faster lens might also be something to consider, but it won't be cheap either.

Here is a review.

Mid-Atlantic Macro Fest -- Cicadas!!

Random Orbits said:
I remember those from the 90s. It was impossible to walk anywhere without hearing them crunching underfoot. Not sure if I'd be looking forward to those again.

Yep, messy and noisy -- but they make for great pictures. They're slow and they stay put, so easy models to work with. The orange/red eyes give you a dramatic, monstrous look.

Does the flash pulse when <x-sync & hss on?

Marsu42 said:
Indeed, my 60d also doesn't to a proper exposure reduction to x-sync but just overexposes -

My old 30D had safety shift, that stopped down until sync speed was ok if required. Did the rip that out?
(That way you lose only the stops from the exessive light value, but don't have to pay the HSS-price, about 40% more flash range)

Physical Ailments From Heavy Gear

Ricku said:
This is why I'm thinking about switching to full frame mirrorless later this year or the next. Leica and Sony have already proven that FF can be small and light.. Right now, uber expensive Leica is the only choice, but rumor is that Sony and Fuji will release their compact FF systems very soon. :P

I hope AF speed will be fast enough for street shooters. I love the IQ on my Sony RX1, but not quite happy with AF speed :(

Highest ISO for good quality video?

Before MK III:
For the best noise performance shot at 160.
For the best latitude shot at 100 with just a very little more noise. You may notice it if you shoot at very low light.
In emergency cases shot at 320 or 640 but you will cope with some noise.

With the MK III go up to 3200 without worries :D
I dunno....I was asking because in the past, I wasn't too concerned about ISO going a little high, and I noticed my videos were plagued with noise, especially in the dark/black areas.

That's because you need at least a little bit of light, "shoots well in low-light" doesn't mean "shoots well in no light." Adding even a minimal amount of light will reduce the noise even at the same ISO.

+1 The only reason why you'd ever need really ridiculously high ISO is so you can stop the aperture down a bit, I think for 99% of situations that matter, you won't need to record video past ISO2500 with an f2.8 lens or brighter. Most wedding receptions with a decent lighting setup by the venue I usually shoot candids from the crowd at about ISO1250 anyway. However, there was this one time at a bar where I cranked my 5D mark III up to ISO 20,000 to expose my drunk friend (expose, in camera terms, lol)....Even then, the grain isn't all that bad if you compare it to most other cameras and normally, people won't really care as long you can still see a fair amount of detail in the image.

Ever borrow from CPS

I'm a gold member and borrowed a 6d from them 2 wks ago and used it on a trip to DC. I didn't have much say in the dates as I was told it was a popular loan, but serendipity intervened. As a result of my experience with that loaner I bought a 6D that arrived today from B&H per the CR price watch page. Excellent.
Anyway.
I didn't even think about insurance, honestly; though Canon lists msrp of 5000 for the body, 24-105L and included accessories. I handled the loaner a little more attentively than my 7D - I was actually evaluating it for purchase, but I don't really bang around my equipment anyway. I sent it back 2-day guaranteed (56.00) which still isn't as expensive as renting as I have in the past, and the equipment is in new-to-refurb condition; which is better for making a true evaluation of it.
I will definitely borrow from Canon again, but expect to limit myself to items I am either considering purchasing, or items I could never imagine affording, in which case I will have to revisit the insurance question...

First big job using FF - for all the FF nay-sayers

Wilmark said:
Is there such a thing as FF nay-sayers? I really doubt it. I think there are FF owners and those who would like to be be FF owners. And the 7D? I used to own one before - its low light performance was really discouraging. I hate to be blunt but the 7d (and the rest of canons line crop line up) sucks and any kind of low light. And those who say they like the 'reach' of the crop sensor cameras, reminds me of the day when people thought that Digital zoom was useful!

Ahem.
Practically it all comes down to whether your uses require more reach than your glass can give you.

If you crop an image shot on full frame you are using "digital zoom". If instead you switch to a good crop sensor, you can get much more detail on the subject.
