Yes, I have been there multiple times but not with my 645D. I'm hopping to do a trip there it the fall to capture some of the nice colours that occur. It's a very popular destination but unfortunately miserable in the summer due to an abundance of bugs.
LOL..tell me about it. One summer vacation I got eaten alive by the bugs there. Other than that, it truly is a wonderful place and would love to go there in the Fall.

Nice work, what lenses do you recommend for portraits on the 645D ? I have high hopes for the 90mm 2.8 that was announced.
I can't speak for Edward, but my favorite portrait lens on the 645D is the Pentax 150mm f2.8 (which gives a focal lens of approx. 120mm in 35mm terms. It's sharp wide open, but not so much so that it renders individuals harshly...and the bokeh is very nice. Somehow I feel the resulting focal length of the new 90mm (being 72mm in 35mm terms), is too short for portraits.

Agreed, + if this new 90mm is not a macro lens, then i don't think it will be a deal-breaker...

What has me perplexed is that of all the focal length or kinds of lenses Pentax could have made for their next 645 lens release, I could think of many others that are needed as opposed to the new 90mm, even if it is a f2.8 macro (in my opinion). For now we have the fantastic 120mm f4 macro which is one of the finest performing Pentax 645 lenses. We have an excellent portrait lens in the 150mm f2.8 (effective 120mm in 35mm terms on the 645D). The new 90mm is effectively 72mm (in 35mm terms), a focal length in my opinion that is neither here nor there. I bet many would have been delighted with a T/S lens for the 645D...possibly a 30mm one which would have given a effective focal length of 24mm (in 35mm terms). This 30mm T/S 645 lens beside being T/S would be a new focal length for Pentax 645 and even if not T/S, would at least given a new wide angle to consider and maybe at a price point less expensive than the new 25mm.

My guess is Pentax's priority with new 645 lenses is making them weather sealed, even if that means releasing lenses in common focal lengths which there is already other similar 645 lenses (but that are of the older non weatherproof design). This is a good approach but I personally believe new lens releases should be more creative.

All the work in this thread is amazing. I can see that the 645D has certainly done well in all your respect hands. The colors and detail are just mind-blowing! The black and whites are staggering.

Keep up the good work and the sharing!

How many 72mm lens do you know of? How is that not creative? There is no 645 90mm lens.

I would recommend the 120mm macro. It is a fairly typical lens for portraiture and there is effectively no minimum focus distance, which is an issue for tight head shots. The Pentax 67 105mm f/2.4 makes another interesting choice. Personally, I love a normal lens for portraiture and did a series using the D FA 55mm and I think the 90mm would be excellent as well--the typical portrait focal lengths make the model too flat for my taste. (There really is no such thing as a portrait lens.)

How about an example or two? I would love to see some of your work here on this thread with various lenses.

Amen, give me a 30mm T/S for 645...given the 645D was designed with primarily outdoor landscape photography in mind, I don't see any use for the 90mm in my case and won't be getting it, nor do I desire to have it. In fact, I'd trade a 30mm T/S for the 25mm anyday...even pay the same price or a little more if the optics were good. I would use that lens all the time. Focus bracketing is just one more thing to have to worry about 'messing up' when shooting the fast changing light of landscapes.

Ok, to change the pace of things . . . . Here is another completely inappropriate use of 645D . . . .

Thanks, larkis. I used a 150mm f/2.8 lens for these shots. I would recommend this lens for tight headshots. The 90 is more of a standard lens in 645 format. Hope this helps.

I agree with Dave. It would also be nice to have a portrait leaf-shutter lens so I could shoot fill flash on-location at 1/500s with a larger aperture. The 645D's flash sync is only 1/125s with the focal-plane shutter. I currently use a 645 75mm f/2.8 leaf-shutter lens and a 67 165mm f/4 leaf-shutter lens with an adapter for fashion shoots outdoors.

Focal lengths for a given purpose are of course a personal choice, especially for portraits. As great a lens as the 120 macro I, I don't find it's the most flattering lens for subtle portraits although they will certainly be razor sharp. I much prefer the 150 f2.8 for portrait purposes.

As for a focal length of 72mm, almost any focal length # in mm that hasn't been used for a Pentax 645 lens is going to be unique, but what I meant is it's an unimaginative focal length to pick as the next release. I'm certtain if you took a poll of 645D uses as to whether they would prefer a 90mm f2.8 645 lens as the next lens release vs. say a 30mm 645 T/S llens, I suspect the 30mm would garner more votes. I"m not saying a 90mm isn't a nice lens to eventually release...just that instead if replacing current 645 lenses with similar WR counterparts, maybe lenses that aren't part of the 645system yet.

Lastly keep in mind we already have the 75mm f2.8...a gem of a little lens, although granted it needs to be stopped down to achieve good resolution. Again we all have personal likes (and dislikes) when it comes to lenses....there is no right or wrong,

Ednguyen,

In a word...Stunning! Wonderful use of the new 55mm. I love to see when lenses are often used in settings and environments that many don't normally associate the lens with. I honestly love all three and each has elements that illustrate your photographic imagination with style and flair, but never loosing sight of the elements that make the model attractive. Nice work!
