Weekly photo, 24 April 2015
Last week I stopped a couple of times along a lake shore to see what I could found, I was able after 3 encounter with a Canada Geese couple to take an interesting photo of one of them last week with my 400mm lens.
This morning I went again to see if I could find frogs, yes they are singing, but this morning it was snowing ….. again 😦
But I saw this Canada Geese couple swimming among the long weeds to find foods. They kept coming closer and closer, in the end they were too close for my 400mm lens. To my surprise the got off the water and walked directly in my direction, I grabbed my K50 which was equipped with my DA 16-85mm, they walked just past me and I had time taking some shots. The light level was very low and I didn’t had time to change my settings and I forgot to turn off the SR ( the shutter speed was fast enough to stop the camera movement but not the birds movements).
I got one shot that is sharp enough (no bird movement) and a good pose by one of the Canada Geese. It’s the first time that I saw Canada Geese coming so close to me, usually they swim or flew away when i’m at around 300 feet !!!
Pentax DA 16-85mm WR early review.
It’s full name is : HD Pentax-DA 16-85mm/3.5-5.6 ED DC WR. I did owned the Canon 15-85mm/3.5-5.6 and liked it a lot because of it’s range and quite good IQ, it was especially useful during our family vacation we took 2 years ago in the province of New Brunswick and P.E.I. here in Canada. The Pentax is even more desirable to my eyes because it incorporates WR, is cheaper than the Canon as well when there is no rebates. The Canon quickly developed zoom creep, which it’s known for, hope the Pentax will do better in that department. They both focus down to 0.35 meter and uses a 72mm filter size.
My first impression when i removed the lens from the box was it’s solid feel in my hand, always a positive thing to feel that a lens can take some abuse. The zooming ring feels stiff enough for the moment to prevent zoom creep, will have to wait after some months of field use to see if it will maintain that stiffness and not suffer from zoom creep.
IQ and field experience
One of the most important selling point of lenses is sharpness, if a lens can’t deliver in that department most people will not buy it. Do you need to absolutely have the sharpest lens available, probably not, but a lens needs to be at least very good. Does the Pentax DA 16-85mm is good enough …….. after shooting for some weeks with it in the field i can say that it’s a very good lens.
The focusing ring is placed close to the mount, which is not my favorite place to put it on a lens, which seems to become a “trend” with lens manufacturer, i prefer the “old” way. It’s probably because now peoples are using lenses mostly in AF mode and it’s a better place to put the zooming ring more at the front of the lens. I would have liked the focusing ring to be larger also but i will live with it. It’s my first Pentax lens with a DC motor and it’s quite fast and silent. The AF is very good in LV at any distances, works really well in the field with most subjects.
Flare control is always very good on Pentax lenses, so this lens is no different than all the other Pentax lenses i’ve owned.
The more i use it the more i find that it’s a very useful lens for nature photography because it’s a complete package.
Close-up , does the image quality is maintained ???
The lens alone can focus quite close at 35cm resulting in a reproduction ratio of 0.26x, which is not bad. My Canon 15-85mm was not so good at 85mm at the minimum focusing distance, the IQ dropped, especially in the corners. Does the Pentax 16-85mm will perform better, will it make a good occasional “Close-up” kit ?
I gave it a try this morning, mounting it on my tripod i photographed some leaves on the ice. First thing i have to say is that the fact that it’s a Zoom makes it easier to change my framing, when using a prime Macro lens if your too close you have to play with the legs of your tripod, not as fast and effective.
I compared it with my Tamron 90mm Macro (model 72E) to see how it really performs at close range. It’s not fair in term of pure sharpness but i needed a benchmark, i’m not expecting the same degree of details from the DA 16-85mm, especially in the corners. But if the quality is good in the center it might be helpful for some Frog shots.
Here is my test subject:
At f/5.6 the Tamron has the advantage by a slight margin but at f/8 (the crop posted here) there is no real advantage, i would call this negligeable for field work. Adding the PP and sharpening and both could be printed quite large with very good IQ.
Pentax came-up with a great lens, from my experience it’s a better lens than the Canon 15-85mm that i was using in the past and it has the bonus of weather sealing !!! It makes a very good combo with my K50 and tough enough to shoot in very bad weather. It fits perfectly for the kind of photography I do, it can be landscape, Close-up or even family photos. With that lens i can do all that in good or bad weather while producing beautifully detailed photos. Like i said, my only complaint is the placement and size of the focusing ring, but that’s a personal thing because i’m using MF a lot in my photography.
Well, some will say that it’s pricey but if you look at how many lenses it replaces and how good it is, even for close-up photos, i think it’s well worth the price. Sure it’s a “slow” lens, if you need a lens with a faster maximum aperture to use in very low light it’s not the lens your looking for. But for a nature photographer who want a good lens that is not too big or heavy, for travelling or for everyday use, i think it’s one of the best option in Pentax land. Pentax really proved with that lens that they can make some excellent zoom lenses, not only small prime lenses. I will post updates when I will be able to try it out on Frogs.
