This week photo is more abstract than usual, I found a Fern that was underwater and also liked the trees reflected on the water surface. So I used a Polarizer to cut off some reflection to be able to see the fern but not too much polarisation so that I could still see the reflection of the trees.
The young American Robin are finally out of their nest and they are easy to find because of their constant demand for food ! You just have to follow their chirping sound ! This little fellow below was high on a branch waiting for one of the parent to bring some foods, unfortunately when one of them brought foods it wasn’t at a good angle and wasn’t worth a good shot. So here is my favorite of the series, the wind was blowing as we can see in it’s feathers.
Over the years i’ve owned several telephoto zoom lenses in that range from different brands: Canon 70-200mm/4L (2 times), Canon 70-300mm/3.5-5.6 IS (non L version), Fuji XF 55-200mm/3.5-4.8 OIS, Pentax DA* 50-135mm/2.8, Sony 70-300mm/3.5-5.6 G series and also many older manual focus lenses! Since i wanted to save weight and have a 2 lens kit when i want to travel light or as a general lens for landscape, tame wildlife and with good close-up ability for some bigger frogs like Green Frogs and Bullfrogs, so i decided to give a chance to that Pentax HD DA 55-300mm/4-5.8 WR. If the IQ is not good enough for me i can always sell it and buy a different lens. My expectations are that it will probably be more in the same league as the Canon 70-300mm IS (non L version) mentioned above.
When i first opened the box i was surprised by how small and lightweight it is, i’m used to bigger lenses in that range. It’s well balanced on my K50 and they will make a great lightweight kit, some will say that it feels big to them, go in a store and try a Canon 7D fitted with a “small” Canon 70-200mm/4L and a TC 1 4x !!!
WR is a big plus for my style of photography
I live in Canada and i encounter all type of bad weather, so it’s one of the reason i came back with Pentax, it’s a lot easier to continue shooting in the rain when you don’t have to protect your gear from it. From my past experience with Pentax DA* and WR lenses i know that i can shoot in very bad weather and be “ZEN”. My favorite subject is Frogs, i’m often shooting along the shore of ponds, so my gear gets muddy and wet most of the time. Up to now it copes with the climate very well.
Well, it’s always a big part of the decision when you consider buying a new lens. I was hoping that this lens would deliver good IQ at 300mm for occasional tame wildlife, showing wildlife in their habitat and at the ZOO (i like to go at different ZOO we have around here). The lens deliver good results in the field especially in the center, i prefer to use it between f/6.3 and f/8 at the longer settings (200mm to 300mm) but I wouldn’t call the IQ tack sharp at these focal lengths. For my general shooting i have no problem to stop it down to f/11-13 at closer range for more intimate landscape photos, especially at focal lengths below 200mm. Sure it’s not in the same league as the lenses i’ve used in the past in that range like the Canon 70-200mm/4 L, Fuji XF 55-200mm or Pentax DA*50-135mm/2.8, but it certainly can compete with the Canon 70-300mm IS (non-L). The corners at the longer focal length are not up to the center but it’s less important since most of the time I will shoot it at wider apertures for wildlife where the corners are not as important.
There is still some CA visible at 300mm at f/8 in high contrast situations but it’s easy to correct it in LR.
Here we go with some real life photos:
BTW, i tested my lens to see if the centering was good and it looks like i have a very good copy in that department.
How does it perform in close-up range with an extension tube
I always try my lenses with extension tubes to see how they perform and if they can be useful for “close-up” shots, especially for Frog photos. The Pentax DA 55-300mm WR alone already focus at 1.40 meter which gives me a 0.28x repro ratio. After some test around my house it performs like my Fuji XF 55-200mm with extension tubes …. it’s not worth it. The corners suffers a lot, my guess is that the image circle that these lenses produce was really made for APS-C sensor and by putting an extension tube the corners IQ drops too much. Most of the lenses i’ve owned over the years were FF lenses or Medium Format lenses, so the corners were always very good when using extension tubes because of their bigger image circle.
Handling in the field
What i found is that you need to support the lens on a solid support or have a fast enough shutter speed when using it from around 200mm to 300mm settings to obtain sharp results and it’s probably why i read on the internet that it was soft at the long end. Because when zoomed in that range it is more prone to vibrations than the other telephoto zoom lenses that i’ve owned (the ones in the first paragraph). Even when using it on a solid tripod if there is some wind or you press the shutter button with your finger when it’s zoomed all the way to 300mm it will be enough to cause vibrations and resulting in a soft photo (even if using the MLU with the 2 second delay). So you have to be more careful in the field when using it at the longer end of the range and that’s the reason i just ordered a remote release. Compared to Pro lenses that doesn’t extend like the DA* 50-135 or the Canon 70-20mm lenses which are stiffer because of that and also they are made more out of metal, the weight helps in windy conditions. When using it handheld if you use a good telephoto shooting technique the lens will deliver good details.
Other than that i really like how it handles and it feels good with my K50. I really like the feeling of the focusing ring, it’s easy to obtain focus when using it in MF with the help of the LV. The only complaint i have is that the focusing ring turns when in AF, so watch your fingers ! I found that my copy needed a +1 adjustment for the AF, good to have that kind of adjustment available in the camera ! AF certainly needs good light to be fast and accurate at the same time, especially at the long end, this might be due to my K50, a K3 would certainly deliver better results.
After some use i can say that the lens will not suffer from Zoom creep, the zooming ring is stiff enough to prevent that, probably a bonus from the WR seals !
It’s a good lens for what it is but if you’re looking for Pro grade IQ …. it’s not the lens to buy. It’s quite good up to about 200mm but after that there is a drop in IQ, you will have to stop it down to around f/6.3-8 to get good sharpness again in the center. If you’re looking for a lightweight telephoto zoom lens, WR and with good IQ in most of it’s range and are willing to stop it down a little …. then it’s a good choice. It will never deliver the same beautiful images that my DA*50-135mm was giving me but it does exactly what i was hoping for when i bought it. As a final point, I will buy another lens in the same range but with better IQ like a DA*60-250mm or the new DFA 70-200mm or even a Canon 70-300mm IS L (we never know) and this lens will be my lightweight telephoto lens.
This morning I went to a local pond where there is many adult Bullfrogs at close range. Some are more tolerant than others, I just need to find a Bullfrog in a beautiful setting and that will let me close. What I liked about this adult male American Bullfrog was the moss on the shore and the perfect reflection.
This morning I went to one of my favorite place for photographing Green Frogs and Bullfrogs. It’s a local Parc with several ponds from small to big, it’s a Frog paradise and photographer paradise 🙂
To get that low view of this Bullfrog I positioned my tripod in the water until I got the framing I wanted.
It’s been a long winter and I was happy to see my first frogs this week ! I was able to photograph my first Green Frogs in one of my favorite pond. I hope that this summer will be great and that I will get some great shots !
