Hi from california, not sure on medium format

Hey everyone,
First timer user long time viewer. Ive been using my k3 for a while and love the images that it produces especially with the pentax hd 16-85 wr lens. until recently i never gave much thought on moving to either full frame or medium format till i was looking at pictures i use to take with 35mm film, along with those awesome shots ive been admiring from mike in the medium format section.

With that in mind, im deciding to move on up to 645 system but not sure what lens and camera i should start out with.

Should i go with the 645d or the 645z?

Which lens should i start out with to get started?

A little bit about my shooting style:
I do landscapes,
mix between day and night,
i love taking pictures of moving water, waterfalls, beaches/sunsets, mountains and cliffs,
Main focal points that i use with my k3 are 16 mm, 26mm, 35mm, 55mm, 100mm, and 300mm

Thank you in advance, and appreciate being part of a great community.

If you can afford the 645Z, that is an absolute no brainer.

Welcome to the forum, +1 on the 645Z, I've heard many a good word and seen many good images from this camera, both here on the forum and elsewhere.

Hi and welcome to the forum!

If you can afford it, go for the 645Z. It's not that the 645D is bad, the Z is so much more. Live view, flip screen, video and there's "no" delay from exposure to preview.

Here's my upgrade path. I also came from the K-3 and bought a 645D 1.5 years ago. I also got a new DFA 55/2.8. Then I started to buy cheap used lenses, A35/3.5, A75/2.8 and A120/4 Macro. Approximately Field of view wise on APS that is: 17, 27, 37 and 60 mm. Similar to what you use today, except the 100 and 300 mm. If you can live with manual focus, they are bargains, with exceptional high quality.

Then I added some FA-lenses (also second hand, used ones): FA150/2.8 and the zoom FA45-85/4.5. They are also great lenses, but a little more expensive, due to the AF.

Then I discovered that 35 mm was not wide enough for some landscapes and architecture: A new DA25/4 was the remedy for that.

On the long end, I got a real bargain A*300/4, then a A200/4, and finally after some searching a FA400/5.6. Just to be sure I also added the RC 1.4 and RC 2.0.

When I found one A*600/5.6, I tried it, but it was to heavy for me.

Comparing to your current 100 and 300 mm on K-3, I would recommend the (F)A200/4, FA400/5.6 and the RC1.4. That should give you approx. the same Field of view that you use today, on the long end.

Don't forget to buy a good bag/ backpack, and a real sturdy tripod. MF gear is heavy.

Looking forward to your photos here on PF.

(Ooops, I forgot the DFA 90/2.8 Macro... Well, well, the severe LBA must have gotten to my memory.)

Thank you. This helps a lot. Especially with the comparison between focal lengths. Gives me some time to think about it before i make the purchase at the beginning of the year.

Now to decide if i should start with the 35mm or the 55mm?

Im trying to resist the lba urge... Although resistance is futile....

thx and I stumbled in here eventually, lol.

To the OP, there has never been a better time to get a 645D, especially for landscape shooting where burst and processing speed are not crucial. Prices are extremely reasonable and low ISO IQ of the D is certainly comparable to the Z. But if you can afford it, why not get the latest and fastest model?

Welcome and good luck shopping!

Well that does make it look enticing. I never really do take high iso photos, and i do use a tripod most of the time

This might be an odd question, but was never able to find an accurate answer on the internet. Generally how large are the raw and jpeg file sizes of the 645d and the 645z?

on the D, i typically see 45-75MB per DNG file. Never generated a jpg, so i can't answer that one.

Santa is likely going to bringing me a Z, so my D is on eBay. That said, I may have both at the same time to shoot some comparisons.
