Bonsoir,

I received today a notification from the shop where I ordered the long awaited PENTAX smc DA* 60-250mm f/4 ED (IF) SDM lens. The lens has been shipped and should arrive at the beginning of next week :!:

After 2 years of delays from Pentax, 5 days for delivery seem short :)

Stay tuned :!:

1- Unboxing

Bonjour,

At last, after 2 years of delays and many, many months of patience, the Pentax smc DA* 60-250mm f/4 ED (IF) SDM was delivered today :!:

First impression: as for the other DA* family lenses, we are dealing with truly pro gear. Solid, heavy, impressive.

On the box, the following disclaimer
Quote:
When this lens is mounted on an *ist D series, K100D, or K110D camera,
autofocus is driven by the camera motor, not the supersonic motor in the lens.

It seems good news for *ist D series, K100D and K110D owners.

Here are some pictures of the out the box experience

Image

Image

Image

Image

More to come: stay tuned ;)

(Sorry for the quality of the pictures: they were taken with a Canon IXUS 85 IS)

2- First hands-on

The smc DA* 60-250mm f/4 ED (IF) SDM is an impressive piece of manufacturing. It's heavy, dense, solid.

Image

It shares the same rings as the SMC DA* 16-50mm F2.8 ED AL [IF] SDM and the SMC DA* 50-135mm F2.8 ED [IF] SDM : one green, another gold

What a name! This lens is packed with so much technology!
    SMC = super multi coating
    ED = Extra-low Dispersion
    IF = Internal Focus
    SDM = Supersonic Direct-drive Motor

The lens comes with a rear cap, a front cap (of a new and better kind, with inner handling), a hood, a tripod mount and a soft case.

Image

Image


There are 3 rings: a first ring is for manual focus, the second for zooming. Both rings are large and comfortable. The third and last one is closer to the camera and allows position shifting when the lens is mounted on a tripod.

Image Image


Due to its heavyness, the 60-250 requires great care when fixing and unfixing it to the K10D. That's not easy, since the fixed part between the two ring is not very large. The usual orange dot is here.

When fixed, the center of gravity is no longer on the K10D, but on the lens. The lens features a tripod mount, close to center of gravity. The tripod mount could set apart, with a 1 ¢ coin.

Image Image

Image Image


When the tripod mount is fixed, the camera and the lens are well centered on the tripod.

Image

Shifting the position is easy with the third ring: here is the result. A screw secures the position.

Image


Contrary to the 50-135 but as the 16-50, the lens moves outside.

Image

Image


A dedicated button switches the auto-focus on and off and is logically connected with the AF selector on the K10D (continuous, single, off). Once again, Pentax ergonomics are great.

Image

The SDM motor is quiet and fast. Actually so quiet that I strongly recommend to set the bip on for focus, through MENU > Preferences > Sound > Focus.

A small windows gives the distance in metric and imperial units.

Image


All this comes at a price. The weight of the K10D and the 60-250mm combined reaches 1.9 kg / 4.2 lb. Because the center of gravity is on the lens, operating the camera with one hand is not that easy. You may use both hands or, better, you may require the BG2 grip, pushing the weight up to 2.1 kg / 4,6 lb! Another consequence is the need of a stronger bag.

Needless to remind that K10D firmware needs to be updated to 1.30.

Stay tuned :!:

Wow congrads again on your purchace Rei!! It looks like a very impressive lens. I look forward to your practice shots with it.

Your review was great but I only have one question for you. As you know I ask a lot of questions. This may be a dumb question to ask but why is it that a lens that size has an Af motor in it. The K10D like many other models of pentax all have AF motors in the camera's. Is it because of the size of the lens it self? Does the body motor lack enough power to focus such a large lens?

It is an important question. Actually, this is an SDM lens, with built-in Supersonic Direct-drive Motor, which proves to be fast and silent.

The lens is also compatible with non-SDM ready cameras. On the box, the following disclaimer claims
Quote:
When this lens is mounted on an *ist D series, K100D, or K110D camera, autofocus is driven by the camera motor, not the supersonic motor in the lens.

Since I own a K10D, I use the SDM feature only and can't test the other one.

More to come :!:

Humm interesting.. Let me know how that goes because if it works with the K10D then it should work with the K200D

3- First pictures

Weather wasn't as good as expected and rather rainy. So I took the first pictures from my flat.

Left in °C and right in °F
Image Image

All the pictures were taken at f/5.6 1/250s iso100. For each picture, I show clock-wise the whole picture, a bottom-left crop and a center crop.

60mm
Image
Image Image

140mm
Image
Image Image

200mm
Image
Image Image

250mm
Image
Image Image

That gives a first idea of the quality of the lens, even if the sun was missing. I see no chromatic aberration and no color fringe.

Stay tuned for sunnier pictures :!:

4- DA* 60-250mm versus DA* 50-135mm

All the pictures were taken at f/5.6 1/250s iso100 and are un-processed.

For each picture, I show on the left 60-250 and on the right 50-135, from top to bottom the whole picture, a bottom-left crop and a center crop.

50mm Left 60-250 and right 50-135
Image Image
Image Image
Image Image

60mm Left 60-250 and right 50-135
Image Image
Image Image
Image Image

135mm Left 60-250 and right 50-135
Image Image
Image Image
Image Image

200mm Left 60-250 and right 50-135
Image Image
Image Image
Image Image

250mm Left 60-250 and right 50-135
Image Image
Image Image
Image Image

Finding differences on quality is difficult. Maybe there's some slight purple fringing on the 60-250 at 60mm.

All the pictures are available in this :arrow: dedicated Picasa album for closer examination.

Bonjour Mystic,

The following image means the lens doesn't offer the focal length.

Image

For instance, the 60-250mm doesn't feature 50mm and the 50-135mm doesn't feature 250mm.

However, I wanted to provide the full scope of both lenses.

Feel free to have a look at the :arrow: dedicated Picasa album for closer examination :)

Best regards,

5- Depth of Field Test

The weather being not so nice :? , I proceed to some depth of field test, fisrt in-house and then outdoor.

Rear - f/4.0 1/15s iso400 250.0 mm
Image

Front - f/4.0 1/15s iso400 250.0 mm
Image

Comparison
Image Image

Now, let's go outdoor with nice flowers :) The choice of the focus area was done with the focus dial set to SEL and then, selecting the specific dot through the view-finder with the 4-way pad.

f/5.6 1/500s iso100 250.0 mm
Image

f/5.6 1/500s iso100 250.0 mm
Image

Don't expect macro photography closer than 1 meter / 3.3 ft. Consider instead the :arrow: Pentax DA* 16-50mm f2.8 ED/AL (IF) SDM.
